Description

Technology Field

[0001] The present invention relates to the field of plant disease control technology, and specifically to five fungicide compositions and their application in the control of Fusarium diseases in crops. Background Technology

[0002] Fusarium (Fusarium spp.) is a fungus distributed worldwide that causes various diseases in plants, such as root rot, stem rot, flower rot, and ear rot, leading to wilting and death of crops and affecting yield and quality. Common Fusarium crop diseases include rice blast, wheat red mold, corn ear rot, cucurbit wilt, and root rot in various crops.

[0003] Due to recent changes in climate and cultivation practices, wheat red mold caused by the Fusarium graminearum complex is posing a serious threat to the safe production of wheat. Unlike other crop diseases, the red mold pathogen produces mycotoxins such as deoxynivalenol (also known as emetic toxin, DON) and zearalenone (ZEA) in infected wheat, posing a serious threat to human and animal safety. Consequently, this disease has been designated as a "Class 1 crop pest" by the Ministry of Agriculture and Rural Affairs. Furthermore, due to large-scale crop rotation between wheat and corn in China, corn ear rot caused by the Fusarium graminearum complex is showing an worsening trend, drawing significant attention from major productivity agriculture and grain procurement departments.

[0004] In addition to Fusarium graminearum, rice blast caused by the Fusarium fujikuroi complex is also a global fungal disease. In China, with the widespread adoption of intensive seedling cultivation techniques such as mechanical transplanting and broadcast sowing, the occurrence of blast has become increasingly common, with incidence rates reaching 100% in some regions, resulting in severe losses in production.

[0005] Fusarium can also cause wilt diseases in various fruits and vegetables; for example, banana wilt disease caused by Fusarium oxysporum causes large-scale wilting and death of bananas, resulting in massive losses for banana farmers and becoming a "cancer" on the banana industry. In addition, wilt diseases caused by Fusarium oxysporum in cucurbit crops, tomatoes, etc., are seriously hindering the healthy development of the industry.

[0006] Therefore, continuous and effective control of Fusarium diseases in crops is of significant importance for the effective supply of agricultural products and the assurance of quality safety in China.

[0007] Due to the current shortage of highly resistant crop varieties, chemical control still predominates for crop Fusarium disease control.

[0008] Currently, triazole fungicides are widely used to control Fusarium diseases in crops. As sterol biosynthesis inhibitors, triazole fungicides inhibit the synthesis of ergosterol in pathogens, thereby inducing changes in membrane-associated cell functions and exerting fungicidal and fungicidal effects. For example, Tebuconazole (chemical name (RS)-1-p-chlorophenyl-4,4-dimethyl-3-(1H-1,2,4-triazole-1-ylmethyl)pent-3-ol) can be used to control various crop diseases such as rust, red mold, powdery mildew, net blight, and root rot. Metconazole: The chemical name 5-(4-chlorophenyl)-2,2-dimethyl-1-(1H-1,2,4-triazole-1-ylmethyl)cyclopentanol can be used to control various diseases in cereal, barley, and legume crops, and it has excellent protective and curative properties along with a long duration of effect. However, due to the long-term use of the agent, Fusarium diseases develop resistance to this type of agent, which affects the control efficacy of the agent.

[0009] Succinate dehydrogenase inhibitor (SDHI) fungicides, such as pydiflumetofen, can be used to control crop diseases caused by Fusarium, such as Fusarium head blight. Pidiflumetofen, chemical name: 3-(difluoromethyl)-N-methoxy-1-methyl-N-[(RS)-1-methyl-2-(2,4,6-trichlorophenyl)ethyl]pyrazole-4-carboxamide, is a new generation succinate dehydrogenase inhibitor (SDHI) developed by Syngenta. This agent acts on respiratory chain complex II to block ATP synthesis and inhibit the growth of pathogens, thereby inducing their death and ultimately achieving the goal of plant disease control. Penflufen, chemical name: 5-fluoro-1,3-dimethyl-N-[2-(4-methylpent-2-yl)phenyl]-1H-pyrazole-4-carboxamide, is an SDHI-class fungicide developed by Bayer. This agent acts on respiratory chain complex II to inhibit ATP synthesis in pathogens and possesses antiseptic, prophylactic, and curative effects. Currently, it is primarily used as a seed treatment; after application, the agent penetrates the germinating seeds and is delivered to the entire plant through the xylem, thereby providing protection. However, succinate dehydrogenase inhibitor fungicides have a single site of action, and the risk of resistance is continuously increasing due to their widespread use.

[0010] Fludioxonil (chemical name: 4-(2,2-difluoro-1,3-benzodiox-4-yl)pyrrole-3-carbonitrile), a pyrrole fungicide, is a commonly used agent for controlling diseases such as wheat stem rot, rice blast, and tomato wilt. This agent primarily inhibits the growth of fungal mycelia by activating the histidine kinase signaling pathway of pathogens. As a seed treatment agent, it is mainly used to control various seed-borne and soil-borne pathogens such as Alternaria, Fusarium, Cephalosporium, Rhizoctonia, and Penicillium. However, according to current research, pathogenic fungi easily develop resistance to this agent, significantly affecting the control efficacy of the agent (Oiki et al., 2022. Wide distribution of resistance to the fungicides fludioxonil and iprodione in Penicillium species. PLOS ONE 17 (1); Dowling et al., 2021. Characterization of high fludioxonil resistance in Botrytis cinerea isolates from calibrachoa flowers. Phytopathology, 111(3): pp.478-484; Wen et al., 2022. Biological and molecular characterizations of field fludioxonil-resistant isolates of Fusarium graminearum. Pesticide biochemistry and physiology, 184: DOI10.1016 / j.pestbp.2022.105101.).

[0011] Prochloraz (chemical name: N-propyl-N-[2-(2,4,6-trichlorophenoxy)ethyl]-imidazole-1-carboxamide) is a broad-spectrum fungicide that exhibits distinct control effects against diseases caused by Ascomycetes and imperfect fungi in various crops. Carbendazim (chemical name: benzimidazole-2-ylcarbamate) is a broad-spectrum, low-toxicity fungicide that primarily interferes with the process of cell mitosis and is effective against some pathogens of the Ascomycetes and most pathogenic fungi of imperfect fungi. Thiophanate-methyl (chemical name: 1,2-bis(3-methoxycarbonyl-2-thiouredo)benzene) is a broad-spectrum, low-toxicity fungicide that possesses conduction-resistant properties. This agent achieves an inhibitory effect on pathogen growth by acting on the β-tubulin of pathogenic fungi to inhibit cell division.

[0012] Azoxystrobin (chemical name: (E)-2-{2-[6-(2-cyanofenoxy)pyrimidine-4-yloxy]phenyl}-3-methoxyacrylate) is a methoxyacrylate fungicide that kills fungal cells by inhibiting mitochondrial respiration through the inhibition of electron transfer between cytochromes bc1 in fungal cells. This agent has excellent control effects against various crop diseases caused by pathogens of the Ascomycota, Basidiomycota, Flagellates, and Deuteromycota subphyla. It is highly efficient and broad-spectrum, exhibiting excellent activity against powdery mildew, rust, waterlogging disease, net blight, downy mildew, and blast in grains, rice, peanuts, grapes, potatoes, fruit trees, vegetables, coffee, and turfgrass, and can be used for foliar spraying, seed treatment, and soil treatment. Trifloxystrobin (chemical name: (E)-methoxyimino-{(E)-α-[1-(α,α,α-trifluoro-m-tolyl)ethylideneaminoxy]-o-tolyl}acetate is broad-spectrum and long-lasting in efficacy, possessing protective, curative, and eradicative activities against most diseases caused by pathogenic fungi, including Ascomycetes, Basidiomycetes, Oomycetes, and Deuteromycetes. It exhibits no cross-resistance with currently existing fungicides. Fluoxastrobin (chemical name: {2-[6-(2-chlorophenoxy)-5-fluoropyrimidine-4-yloxy]phenyl}(5,6-dihydro-1,4,2-dioxazine-3-yl)methanone O-methyloxime) has broad-spectrum fungicidal activity and exhibits very good activity against diseases of almost all fungi (Ascomycetes, Basidiomycetes, Oomycetes, and Deuteromycetes), such as rust, waterlogged disease, net blight, powdery mildew, and downy mildew. Picoxystrobin (chemical name: (E)-3-methoxy-2-{2-[6-(trifluoromethyl)-2-pyridyloxymethyl]phenyl}acrylate belongs to broad-spectrum anaerobic fungicides.Pyraclostrobin (chemical name: N-[2-[[1-(4-chlorophenyl)pyrazole-3-yl]oxymethyl]phenyl]-N-methoxycarbamate) possesses protective and therapeutic effects, as well as water absorption conductivity and rain resistance, and has a relatively wide range of applications. Phenaminstrobin (chemical name: (E,E,E)-N-methyl-2-[((((1-methyl-3-(2,6-dichlorophenyl)-2-propenyl)imino)oxy)methyl)phenyl]-2-methoxyiminoacetamide) has a broad fungicidal spectrum, high activity, and possesses preventive and therapeutic effects. It exhibits excellent control efficacy against various plant diseases caused by flagellates, zygomycetes, ascomycetes, basidiomycetes, and imperfect fungi, and shows outstanding control effects against powdery mildew and rust.

[0013] Long-term use of pesticides allows pathogens to easily develop resistance, affecting their control efficacy. Therefore, the research and development of appropriate pesticide combinations for controlling Fusarium diseases in crops is particularly important. The problem to be solved

[0014] The objective of the present invention is to provide a high-efficiency, low-toxicity, and environmentally friendly fungicide composition that is highly effective against crop diseases caused by Fusarium, while simultaneously delaying drug resistance and extending the service life of the drug. means of solving the problem

[0015] It can delay resistance and extend the lifespan of the drug.

[0016] To achieve the above objective, the present invention adopts the following technical solution.

[0017] In a first aspect of the present invention, the present invention provides a sterilizing composition, wherein the active ingredient of the composition comprises a compound ZJS178 represented by the structural formula (I) and a triazole-based sterilizing agent.

[0018] (I)

[0019] The above compound ZJS178 is a new compound previously prepared by the research team of the present invention, and its chemical name is ethyl 2-cyano-3-amino-3-[4-(N-ethyl-N-methylamino)phenyl]acrylate, and its synthesis route is as follows.

[0020]

[0021] The compound is a cyanoacrylate-based fungicide that acts on Fusarium type I myosin (motor protein) to cause the pathogen to lose its growth momentum, thereby killing the pathogen. According to research, ZJS178 has a novel structure and a unique mode of action, exhibits no cross-resistance with triazole-based agents, is effective against diseases caused by Fusariums, and possesses both protective and therapeutic effects.

[0022] Since ZJS178 and triazole fungicides have different mechanisms of action, the present invention combines the two to achieve a significantly higher control effect against Fusarium diseases in crops compared to a single agent, reduces the amount of single agent used, delays the development of drug resistance in pathogens, extends the service life of the fungicide, and helps reduce costs.

[0023] Preferably, the mass ratio of compound ZJS178 to triazole-based disinfectant in the composition is 50:1 to 1:50.

[0024] The above triazole-based disinfectants include, but are not limited to, tebuconazole, metconazole, micerobutanil, diphenoconazole, triadimefon, epoxyconazole, diniconazole, prothioconazole, propiconazole, etc.

[0025] Preferably, the triazole-based disinfectant is tebuconazole or metconazole.

[0026] Furthermore, preferably, the mass ratio of compound ZJS178 to triazole-based fungicide in the composition is 15:1 to 1:15.

[0027] According to research, compound ZJS178 and triazole fungicides exhibit synergistic effects under specific mixing ratio conditions, thereby enhancing the efficacy of controlling Fusarium diseases. For example, against Fusarium oxysporum, compound ZJS178 and triazole fungicides exhibit enhanced efficacy when mixed in a mass ratio of 8:1 to 1:8. Against Fusarium fujikuroi, compound ZJS178 and triazole fungicides exhibit enhanced efficacy in inhibiting metconazole-susceptible Fusarium fujikuroi when mixed in a mass ratio of 4:1 to 1:5, and the two components exhibit enhanced efficacy in inhibiting metconazole-resistant Fusarium fujikuroi when mixed in a mass ratio of 5:1 to 1:3.

[0028] Preferably, the mass ratio of compound ZJS178 to triazole-based disinfectant in the composition is 8:1 to 1:8.

[0029] More preferably, the mass ratio of compound ZJS178 and the triazole fungicide is mixed in a ratio of 2:1 to 1:3.

[0030] Furthermore, the above-mentioned sterilization composition further includes auxiliary components necessary for pesticide formulations, and the mass ratio of the active component in the composition is 1 to 90%. The above-mentioned auxiliary components are carriers and adjuvants commonly used in pesticides.

[0031] Preferably, the mass percentage of the active ingredient in the composition is 15 to 40%.

[0032] In accordance with methods known to those skilled in the art, the sterilizing composition of the present invention may be prepared in various formulations that are agriculturally acceptable for actual application, and includes water-dispersible granules, suspensions, aqueous emulsions, microemulsions, and suspensions for seed treatment.

As solvents, xylene, toluene, cyclohexanone, and solvent oils (S-150, S-180, S-200) can be selected. As stabilizers, triphenyl phosphite, epichlorohydrin, and acetic anhydride can be selected. Xanthan gum, polyvinyl alcohol, bentonite, and aluminum magnesium silicate can be selected as thickeners. Methanol, benzoic acid, and sodium benzoate can be selected as preservatives.

[0036] The following are adjuvants that can be used for the microemulsion type: As emulsifiers, calcium dodecylbenzenesulfonate (pesticide emulsifier 500#), pesticide emulsifier 700#, pesticide emulsifier 2201#, Span-60#, Tween-80-60#, TX-10, pesticide emulsifier 1601, pesticide emulsifier 600#, and pesticide emulsifier 400# can be selected.

[0038] The present invention further provides the application of the above fungicide composition in the control of crop diseases caused by Fusarium.

[0039] Furthermore, the above Fusarium refers to plant pathogenic Fusarium and mainly includes Fusarium graminearum complex, Fusarium fujikuroi complex, Fusarium oxysporum and Fusarium moniliforme, etc.

[0040] Furthermore, the above crop diseases include wheat red mold, rice blast, and strawberry wilt.

[0041] Specifically, in the application for controlling wheat red mold disease, the fungicide composition is used at the early stage of heading and flowering of wheat, and the agent is used again at intervals of 6 to 7 days.

[0042] In a second aspect of the present invention, the present invention provides a high-efficiency sterilization composition, wherein the active ingredient of the composition comprises a compound ZJS178 represented by the structural formula (I) and a succinate dehydrogenase inhibitor-based sterilizer.

[0043] (I)

[0044] The above compound ZJS178 is a new compound previously prepared by the research team of the present invention, and its chemical name is ethyl 2-cyano-3-amino-3-[4-(N-ethyl-N-methylamino)phenyl]acrylate, and its synthesis route is as follows.

[0045]

[0046] The compound in question is a cyanoacrylate-based fungicide that acts on the myosin type I of Fusarium. Myosin type I is a motor protein of pathogens that hydrolyzes ATP to convert biological energy into mechanical energy, thereby providing power for life activities such as growth, infection, and toxin synthesis. ZJS178 specifically acts on the myosin type I of Fusarium to cause the pathogens to lose their growth power, thereby killing the pathogens.

[0047] ZJS178 has a novel structure and a unique mechanism of action. Studies show that ZJS178 does not exhibit cross-resistance with succinate dehydrogenase inhibitors (SDHI), is effective against diseases caused by Fusariums, and possesses both protective and therapeutic effects.

[0048] Although ZJS178 and SDHI-based fungicides have different mechanisms of action, their sites of action are related; therefore, the present invention combines these two to significantly enhance the fungicidal effect, delay the development of drug resistance in pathogens, and reduce control costs. Specifically, SDHI-based fungicides can effectively inhibit ATP synthesis in pathogens, and rationally combining ZJS178 and SDHI agents allows for the simultaneous blocking of ATP synthesis and motor protein activity. This is akin to simultaneously blocking the pathogen's "gasoline" and "engine," thereby achieving the effect of inhibiting pathogen growth with high efficiency and delaying the pathogen from developing resistance to either agent.

[0049] Preferably, the mass ratio of compound ZJS178 to succinate dehydrogenase inhibitor-based disinfectant in the composition is 50:1 to 1:50.

[0051] Preferably, the mass ratio of compound ZJS178 to succinate dehydrogenase inhibitor-based disinfectant in the composition is 9:1 to 1:9.

[0052] According to research, compound ZJS178 and succinate dehydrogenase inhibitor fungicides exhibit a synergistic effect under specific mixing ratio conditions, thereby enhancing the effectiveness of Fusarium disease control. When the mass ratio of compound ZJS178 to succinate dehydrogenase inhibitor fungicides in the composition is 7:1 to 1:5, it enhances the effectiveness of inhibiting Fusarium graminearum and Fusarium fujikuroi.

[0053] Furthermore, the high-efficiency sterilization composition further includes a pesticide-acceptable carrier and an adjuvant. The mass ratio of the active ingredient in the composition is 1 to 90%.

[0054] Preferably, the mass ratio of the active ingredient in the composition is 10-40%.

[0062] Furthermore, the above Fusarium refers to plant pathogenic Fusarium and mainly includes Fusarium graminearum complex, Fusarium fujikuroi complex, Fusarium oxysporum and Fusarium moniliforme, etc.

[0063] Furthermore, crop diseases caused by Fusarium include, but are not limited to, wheat red mold and rice blast.

[0065] In a third aspect of the present invention, the present invention provides a disinfectant composition, wherein the active ingredient of the composition comprises a compound ZJS178 represented by the structural formula (I) and a pyrrole-based disinfectant.

[0066] (I)

[0068]

[0069] The compound is a cyanoacrylate-based fungicide that acts on Fusarium's type I myosin (motor protein) to cause the pathogen to lose its growth momentum and kill the pathogen.

[0070] Compound ZJS178 has a novel structure and a unique mode of action, and does not exhibit cross-resistance with pyrrole-based agents such as fludioxonil. Since ZJS178 and pyrrole-based disinfectants have different mechanisms of action, the present invention combines the two to expand the range of bactericidal activity and enhance the bactericidal effect, as well as delay the development of drug resistance in pathogens.

[0143] Example 1: Synthesis of Compound ZJS178

[0144] Step 1: Synthesis of intermediate b

[0145]

[0146] 7.0 g of raw material a (CAS number: 67710-36-5) and 150 mL of dichloromethane were placed in a reaction flask. Under an ice bath, 11.7 g of Boc acid anhydride was added, followed by the slow addition of 6.0 g of triethylamine and 3.3 g of DMAP. The mixture was stirred continuously under an ice bath for 0.5 hours, then heated to room temperature and stirred for another 5 hours. After the reaction was complete, 1 M hydrochloric acid was added to the reaction mixture, and the organic layer was separated and washed once each with distilled water and saturated saline solution. The organic layer was dried with anhydrous Na2SO4 and concentrated to obtain 9.6 g of intermediate b, which was used directly in the next step of the reaction without further purification.

[0147] Step 2: Synthesis of intermediate c

[0148]

[0149] 9.6 g of intermediate b, 120 mL of ethanol, and 24 mL of water were added to a reaction flask and heated to 90°C. Then, 3.7 g of iron and 12 mL of saturated ammonium chloride solution were added, and the reaction was continued for 4 hours. After the reaction was finished, diatomite was added and the mixture was filtered. The filtrate was concentrated, water was added, and the mixture was extracted three times with ethyl acetate. The organic layers were combined and concentrated, then separated by column chromatography (the eluent consisted of ethyl acetate and petroleum ether, in a volume ratio of 1:2). 4.5 g of intermediate c was obtained, with a yield of 51.1%.

[0150] Step 3: Synthesis of intermediate d

[0151]

[0152] 0.19 g of sodium hydride was added to 20 mL of tetrahydrofuran under an ice bath, followed by the addition of 1.0 g of intermediate c. The mixture was then heated to room temperature and stirred for 30 minutes. Then, 0.74 g of ethyl iodide was added and stirred overnight at room temperature. After the reaction was complete, water was added to terminate the reaction, and the mixture was extracted three times with ethyl acetate. The organic layers were combined and concentrated, then separated by column chromatography (the eluent consisted of ethyl acetate and petroleum ether, in a volume ratio of 1:5). 0.52 g of intermediate d was obtained, with a yield of 48.0%.

[0153] Step 4: Synthesis of intermediate e

[0154]

[0155] 0.11 g of sodium hydride was added to 10 mL of tetrahydrofuran under an ice bath, followed by the addition of 0.5 g of intermediate d, and the mixture was heated to room temperature and stirred for 30 minutes. Then, 0.40 g of methyl iodide was added and the mixture was stirred overnight at room temperature. After the reaction was complete, water was added to terminate the reaction, and the mixture was extracted three times with ethyl acetate. The organic layers were combined and concentrated, then separated by column chromatography (the eluent consisted of ethyl acetate and petroleum ether, in a volume ratio of 1:5), yielding 0.34 g of intermediate e, with a yield of 65.5%.

After the reaction was finished, an aqueous solution of saturated sodium bicarbonate was added and extracted twice with ethyl acetate. The organic layers were combined and concentrated, then separated by column chromatography (the eluent consisted of ethyl acetate and petroleum ether, in a volume ratio of 1:2), yielding 0.22 g of compound ZJS178, with a yield of 93.2%.

[0159] Example 2: Measurement of indoor toxicity of ZJS178 and tebuconazole combination against wheat red mold pathogen

[0160] Test subjects: Tebuconazole-susceptible (TS) and TR-resistant (TR) wheat red mold fungi (*Fusarium graminearum*) isolated from packaging. After identifying morphology, pathogenicity, and drug resistance, the test strains were preserved in this laboratory for use.

[0161] Test agent: ZJS178 was synthesized in Example 1; tebuconazole (provided by Zhejiang Chemical Research Institute).

[0162] Test Method: The mycelial growth rate method of the <Agricultural Industry Standard of the People's Republic of China NY / T 1156.2-2006> was referenced. For each agent, five dose treatments were established based on the content of the active ingredient, and the pathogen growth inhibition rate was set to be between 10% and 90%. The above-mentioned wheat red mold pathogen was inoculated onto PDA medium, and after waiting until the colony filled 2 / 3 of the culture dish, a mycelial disc was created from the edge of the colony using a 5 mm diameter punch. The mycelial disc was then transferred to the center of a pre-prepared agent-containing medium plate using an inoculation needle, and after incubation in a 25°C incubator for 3 days, the colony diameter of each treatment was measured using calipers with the cross-cross method, and the corrected inhibition percentage was calculated. Subsequently, the EC50 value of each agent was calculated through linear regression analysis between the probability value of the inhibition rate and the logarithm of the continuous concentration, and each treatment was repeated 4 times. ZJS178 is set as the standard drug, and the contingent toxicity factor (CTC) is calculated according to the following formula.

[0163] Actual Toxicity Index (ATI) = (EC50 of Standard Agent / EC50 of Test Agent) × 100;

[0164] Theoretical Toxicity Index (TTI) = Standard Drug Toxicity Index × Percentage of Standard Drug in Mixed Composition + Test Drug Toxicity Index × Percentage of Test Drug in Mixed Composition;

[0165] Co-toxicity Factor (CTC) = (ATI / TTI) × 100%;

[0166] If the CTC value is less than 80, the drug combination exhibits an antagonistic effect; if it is between 80 and 120, it exhibits an additive effect; and if it is greater than 120, it exhibits an effect-enhancing effect.

[0167] The test results are shown in Table 1 and Table 2.

[0179]

[0180] Table 4: Results of indoor toxicity measurements of ZJS178 and metconazole combinations against metconazole-resistant rice blast pathogens (MR).

[0181]

[0182] As shown in Tables 3 and 4, ZJS178 has a very strong inhibitory effect on the mycelial growth of metconazole (MR) and susceptible (MS) rice blast pathogens. The 3:1, 2:1, 1:1, 1:2, and 1:3 combinations of ZJS178 and metconazole exhibit an amplifying effect against both resistant and susceptible strains.

[0183] Example 4: Measurement of indoor toxicity of ZJS178 and tebuconazole combination against strawberry wilt pathogens

[0184] Test subjects: Strawberry wilt pathogen (Fusarium oxysporum) isolated from diseased strawberries in the field. The test strains were preserved in this laboratory after morphological and pathogenic identification.

[0185] Test agent: ZJS178 was synthesized in Example 1; tebuconazole (provided by Zhejiang Chemical Research Institute).

[0186] The bioassay method was referenced in Example 2.

[0187] The test results are shown in Table 5.

[0188] Table 5: Results of indoor toxicity measurements of the ZJS178 and tebuconazole mixture against strawberry wilt pathogens

[0189]

[0190] As can be seen from the results in Table 5, the combination of ZJS178 and tebuconazole has an effect-enhancing effect and can significantly improve the antibacterial effect of the drug against strawberry wilt pathogens.

[0225] Example 6: Measurement of indoor toxicity of ZJS178 and pidiflumethofene combination against wheat red mold

[0226] Test Subject: Wheat red mold pathogen (Fusarium graminearum). It was isolated from the field and identified as Fusarium graminearum using biological methods such as morphology and pathogenicity. It was preserved in this laboratory for use.

[0227] Test agent: ZJS178 is the synthetic of Example 1, pidiflumetofen (Syngenta Nantong Crop Protection Co., Ltd., commercial product).

[0228] Test method: The mycelial growth rate method of the <Agricultural Industry Standard of the People's Republic of China NY / T 1156.2-2006> was referenced. For each agent, five dose treatments were established according to the content of the active ingredient, and the pathogen growth inhibition rate was set to be between 10% and 90%. The above wheat red mold pathogen was inoculated onto a PDA medium, and after waiting until the colony filled 2 / 3 of the culture dish, a mycelial disc was made from the edge of the colony using a 5 mm diameter punch, and the mycelial disc was transferred to the center of a pre-prepared agent-containing medium using an inoculation needle. After incubation in a 25°C incubator for 3 days, the colony diameter (cm) of each treatment group was measured using calipers with the cross-cross method, and the corrected inhibition percentage was calculated. Then, the EC50 value of each agent was calculated through linear regression analysis between the probability value of the inhibition rate and the logarithm of the continuous concentration, and each treatment was repeated 4 times. ZJS178 is set as the standard drug, and the contingent toxicity factor (CTC) is calculated according to the following formula.

[0229] Actual Toxicity Index (ATI) = (EC50 of Standard Agent / EC50 of Test Agent) × 100;

[0230] Theoretical Toxicity Index (TTI) = Standard Drug Toxicity Index × Percentage of Standard Drug in Mixed Composition + Test Drug Toxicity Index × Percentage of Test Drug in Mixed Composition;

[0231] Co-toxicity Factor (CTC) = (ATI / TTI) × 100%;

[0232] If the CTC value is less than 80, the drug combination exhibits an antagonistic effect; if it is between 80 and 120, it exhibits an additive effect; and if it is greater than 120, it exhibits an effect-enhancing effect.

[0233] The test results are shown in Table 7.

[0335] Test agents: ZJS178 was synthesized in Example 1, and thiophanate-methyl was provided by the Zhejiang Chemical Research Institute.

[0336] Test Method: The mycelial growth rate method of the <Agricultural Industry Standard of the People's Republic of China NY / T 1156.2-2006> was referenced. For each agent, five dose treatments were established based on the content of the active ingredient, and the pathogen growth inhibition rate was set to be between 10% and 90%. The above watermelon wilt pathogen was inoculated onto PDA medium, and after waiting until the colony filled 2 / 3 of the culture dish, a mycelial disc was created from the edge of the colony using a 5 mm diameter punch. The mycelial disc was then transferred to the center of a pre-prepared agent-containing medium plate using an inoculation needle, and after incubation in a 25°C incubator for 3 days, the colony diameter of each treatment was measured using calipers with the cross-sectional method, and the corrected inhibition percentage was calculated. Subsequently, the EC50 value of each agent was calculated through linear regression analysis between the probability value of the inhibition rate and the logarithm of the continuous concentration, and each treatment was repeated 4 times. ZJS178 is set as the standard drug, and the contingent toxicity factor (CTC) is calculated according to the following formula.

[0337] Actual Toxicity Index (ATI) = (EC50 of Standard Agent / EC50 of Test Agent) × 100;

For each drug, five dose treatments were established according to the content of the active ingredient. The aforementioned wheat red mold pathogen was cultured on PDA medium. After waiting until the colony filled two-thirds of the culture dish, a mycelial disc was created from the edge of the colony using a 5 mm diameter punch. The mycelial disc was then transferred to the center of the pre-prepared drug-containing PDA medium using an inoculation needle and incubated in a 25°C incubator. Each treatment was repeated four times. The colony growth status of the control group was observed, and the colony diameter (cm) of each treatment group was measured using calipers via the cross-cross method to determine the corrected inhibition percentage. The EC50 value of each drug was calculated through linear regression analysis between the probability value of the inhibition rate and the logarithm of the continuous concentration, and the Co-Target Toxicity (CTC) was calculated according to the Sun Yunfei method.

[0348] Calculation of Efficacy: The size of the colony is represented by the average of the two cross-sectional diameters of each colony. The colony growth inhibition rate is calculated using the following formula: Colony Growth Inhibition Rate % = (Blank Control Colony Growth Diameter - Pharmacological Treatment Colony Growth Diameter) × 100 / Blank Control Colony Growth Diameter.

[0391] Example 17: Measurement of indoor toxicity of ZJS178 and azoxystrobin combination against tomato wilt pathogens

[0392] Test subjects: Tomato wilt pathogen (F. oxysporum f. sp. lycopersici) isolated from diseased tomatoes. After identifying the morphology and pathogenicity of the test strains, they were preserved in this laboratory for use.

[0393] Test agent: ZJS178 was synthesized in Example 1; azoxystrobin was provided by the Zhejiang Research Institute of Chemical Engineering.

[0394] Test method: The mycelial growth rate method of the <Agricultural Industry Standard of the People's Republic of China NY / T 1156.2-2006> was referenced. For each agent, five dose treatments were established according to the content of the active ingredient, and the pathogen growth inhibition rate was set to be between 10% and 90%. The above tomato wilt pathogen was inoculated onto a PDA medium, and 50 μg / ml salicyl hydroxyloxamic acid (SHAM) was added to the medium to inhibit the alternative respiration of the pathogen. After waiting until the colony filled 2 / 3 of the culture dish, a mycelial disc was made from the edge of the colony using a 5 mm diameter punch, and the mycelial disc was transferred to the center of a pre-prepared agent-containing medium plate using an inoculation needle. After incubation in a 25°C incubator for 3 days, the colony diameter of each treatment was measured using calipers with the cross-cross method, and the corrected inhibition percentage was calculated. Next, the EC50 value of each drug is calculated through linear regression analysis between the probability value of the inhibition rate and the logarithm of the continuous concentration, and each treatment is repeated 4 times. ZJS178 is set as the standard drug, and the co-toxicity coefficient (CTC) is calculated according to the following formula.

[0395] Actual Toxicity Index (ATI) = (EC50 of Standard Agent / EC50 of Test Agent) × 100;

[0396] Theoretical Toxicity Index (TTI) = Standard Drug Toxicity Index × Percentage of Standard Drug in Mixed Composition + Test Drug Toxicity Index × Percentage of Test Drug in Mixed Composition;

[0397] Co-toxicity Factor (CTC) = (ATI / TTI) × 100%;

[0398] If the CTC value is less than 80, the drug combination exhibits an antagonistic effect; if it is between 80 and 120, it exhibits an additive effect; and if it is greater than 120, it exhibits an effect-enhancing effect.

[0399] The test results are shown in Table 22.
