Description

[0001] This application is a divisional application of application number CN201910072438.3, filed on January 25, 2019, and entitled “An Insecticide Composition Containing Flufenacet and a Bio-Source Insecticide” Technical Field

[0002] The invention belongs to the technical field of pesticides and relates to an application of an insecticide composition containing flubendiamide and a bio-source insecticide in preventing and controlling crop pests. Background Art

[0003] Crop pests and diseases are among my country's major agricultural disasters. They are numerous, impactful, and frequently erupt. Their scope and severity often cause significant losses to my country's national economy, particularly agricultural production. Common crop pests and diseases in my country include the rice leaf roller, the striped stem borer, the beet armyworm, the diamondback moth, the rice planthopper, powdery mildew, the corn borer, the cotton bollworm, wheat rust, the cotton aphid, rice sheath blight, rice blast, the wheat aphid, the wheat spider mite, locusts, and wheat head blight. These pests have become significant pests and diseases that severely impact agricultural production. Long-term use of chemical pesticides has led to varying degrees of resistance to a variety of chemical insecticides, including organochlorines, organophosphates, carbamates, and pyrethroids. This has significantly reduced the effectiveness of these pesticides, forcing farmers to increase pesticide dosages to improve their effectiveness, which in turn reduces the safety of agricultural products.

[0004] Flufenac, a new compound independently developed by our company, belongs to the benzamide class of insecticides. It effectively activates insect ryanodine (muscle) receptors, leading to excessive release of calcium ions from intracellular calcium stores, causing paralysis and death. It has high activity against lepidopteran larvae, a broad spectrum of insecticides, and long-lasting efficacy. This active ingredient exhibits significant selectivity differences between mammalian and insect ryanodine receptors, significantly enhancing its safety for mammals and other vertebrates.

[0005] Biopesticides are pesticides that use biological metabolites as their primary insecticide ingredients. They are extracted and developed through artificial fermentation processes to kill pests. These pesticides pose minimal environmental risk and are less likely to leave residues, making them a key area of ​​modern pesticide development. Common biopesticides include avermectin, spinosad, spinetoram, Bacillus thuringiensis, avermectin, avermectin benzoate (emamectin benzoate), sucrose octacarboxylate, Beauveria bassiana, Metarhizium anisopliae, nuclear polyhedrosis virus, cytoplasmic polyhedrosis virus, and granulovirus.

[0006] In the actual production process of agricultural production, the most likely problem of pest control is the generation of insect resistance. Compounding of ingredients with different mechanisms of action is a very common method for controlling resistant pests. Different ingredients are compounded, and according to the actual application effect, it is judged whether a certain compounding is synergistic, additive or antagonistic, especially the compounding with very obvious synergistic effect and high co-toxicity coefficient is even less. Through research by the inventor, it is found that after compounding flubendiamide with biogenic insecticide, good synergistic effect can be produced, and the relevant report about the compounding of flubendiamide and biogenic insecticide is not yet disclosed.

[0224] Indoor active cases

[0225] The present invention utilizes a method that combines laboratory toxicity testing with field trials. First, through laboratory toxicity testing, the co-toxicity coefficient (CTC) of two agents mixed in a certain ratio is determined. A CTC of less than 80 indicates antagonism, a CTC of greater than 120 indicates synergism, and a CTC between 80 and 120 indicates additive effect. Based on this, field trials are then conducted.

[0226] Test method: Use the leaf immersion method. Soak the leaves in the drug solution for 5 seconds, then take them out and dry them naturally. Place them in an insect box and then inoculate the test larvae. Raise them at 25°C. Repeat 4 times per treatment, with 20 test larvae per replicate. Set up a blank control at the same time. Check the number of dead insects after 48 hours, calculate the mortality rate and the adjusted mortality rate, and calculate the toxicity regression equation and LC. 50 If the control mortality rate is greater than 10%, the test is considered invalid. The calculation formula is as follows:

[0227]

[0228] LC 50 The agent with a relatively small value is the standard agent, and its toxicity index TI is 100.

[0229]

[0230] Toxicity index of mixture TTI=TI A ×P A +TI B ×P B

[0231]

[0232] Where: P A 、P B are the proportions of active ingredients A and B in the composition, respectively.

[0233] A is flubendiamide.

[0234] B is avermectin.

[0235] Example 61: Combined toxicity of a mixture of flubendiamide and avermectin against cabbage aphids

[0236] Test pests: Cabbage aphids

[0237] Experimental agents: flufenac technical and avermectin technical, both provided by Hailier Pharmaceutical Group Co., Ltd.

[0238] Experimental design: The median lethal concentration (LC50) of flufenacet technical, avermectin technical and their mixtures in different ratios was determined through experiments. 50 ) and co-toxicity coefficient to determine the type of combined action of the mixture of flubendiamide and avermectin against cabbage aphids.

[0239] Table 1 The results of toxicity test of the mixture of flubendiamide and avermectin to cabbage aphids

[0240]

[0241]

[0242] As can be seen from Table 1, the co-toxicity coefficients of fluchlorfenapyr and avermectin against cabbage aphids are greater than 80 when the weight ratio of fluchlorfenapyr and avermectin is 1:80-80:1, indicating that the two exhibit additive or synergistic effects when mixed within the range of 1:80-80:1, and no antagonistic effect occurs; when the weight ratio of fluchlorfenapyr to avermectin is 1:50-50:1, the co-toxicity coefficients are greater than 120, indicating that the two exhibit synergistic effects within this mixing weight ratio range; when the weight ratio of fluchlorfenapyr to avermectin is 1:20-10:1, the co-toxicity coefficients are greater than 170, indicating that the two exhibit significant synergism within this mixing weight ratio range; when the weight ratio of fluchlorfenapyr to avermectin is 1:5-5:1, the co-toxicity coefficients are greater than 200, indicating that the synergistic effect of the two is more prominent within this mixing weight ratio range.

[0243] The inventors have found through experiments that when the mixing ratio of flufenacet and avermectin is 1:3, 1:2, 1:1, 2:1, and 3:1, it has a significant synergistic effect on the prevention and control of Lepidoptera and Homoptera insects of various crops, such as diamondback moth, whitefly, leafhopper, rice leaf roller, striped stem borer, rice planthopper, cotton bollworm, Spodoptera litura, aphids, mites, and thrips. The synergistic effect is obvious, and the co-toxicity coefficient is greater than 120.

[0244] Field efficacy cases

[0245] The experimental drugs were developed and provided by the R&D center of Hailier Pharmaceutical Group Co., Ltd., and the control drugs were selected from 10% flubendiamide suspension, 5% avermectin emulsifiable concentrate, 10% spinosad suspension, 25% ethyl spinetoram water dispersible granules, and 3% emamectin microemulsion, all of which were self-prepared preparations.

[0246] Example 62: Field efficacy test of a mixture of flubendiamide and active ingredient B for controlling Plutella xylostella.

[0247] Test agents and field treatments: The test agents and dosages are shown in Table 2; each treatment was repeated 4 times.

[0248] Test method: According to the test design, the area of ​​each treatment area is 15m 2 , replicated four times, in randomized block arrangements. Baseline insect populations were investigated before application, and control efficacy was assessed 1, 3, and 7 days after application. Five random sampling points were selected, with larval populations of each instar at five selected sites. Each treatment was applied once, and the remaining insect population was assessed 1, 3, and 7 days after application.

[0249] Data Analysis:

[0250] Pest reduction rate (%) = (pest population before treatment - pest population after treatment) / pest population before treatment × 100

[0251] Corrected control efficacy % = (insect population reduction rate in treated area - insect population reduction rate in control area) × 100 / (100 - insect population reduction rate in control area)

[0252] Test results: See Table 2.

[0255]

[0256] Table 2 shows that flufenacet mixed with active ingredient B effectively controls Plutella brassicae. One day after application, the control efficacy ranged from 71.54% to 73.01%, higher than that achieved with a single dose, but the effectiveness was modest. Three days after application, the efficacy was 81.09% to 89%, and seven days after application, it was 86.95% to 90.55%, both higher than with a single dose, and meeting the efficacy indicators.

[0257] Within the scope of experimental drug use, there is no adverse effect on the safety of target crops.

[0259] Test agents and field treatments: The test agents and dosages are shown in Table 3; each treatment was repeated 4 times.

[0260] Test Method: Four replicates were applied per treatment, using the designed dosage. Before application, five sampling points were selected, with two cabbages marked at each point to determine the baseline insect population. Live insect counts were determined on the marked cabbages one, three, and seven days after application. The insect population reduction rate and corrected control efficacy were calculated.

[0261] Data Analysis:

[0262] Pest reduction rate (%) = (pest population before treatment - pest population after treatment) / pest population before treatment × 100

[0263] Corrected control efficacy % = (insect population reduction rate in treated area - insect population reduction rate in control area) × 100 / (100 - insect population reduction rate in control area)

[0264] Test results: See Table 3.

[0265] Table 3 Results of efficacy test of flufenacet and active ingredient B mixed to control cabbage beet armyworm

[0266]

[0267]

[0268] As shown in Table 3, the mixture of flubendiamide and active ingredient B can effectively control cabbage beet armyworm. One day after the test agent was applied, the control effect was not ideal, with a control effect of 65.44% to 72.34%; three days after the application, the control effect began to be more significant than that of a single agent, with a control effect of 80.54% to 86.85%; seven days after the application, the control effect was significantly better than that of a single agent, with a control effect of more than 90%.

[0269] The test results showed that the test agent had moderately fast-acting efficacy against beet armyworm, but exhibited strong long-lasting efficacy. Furthermore, compared to a single dose, the test agent demonstrated significantly superior control three days after application. Within the test range, the agent demonstrated no adverse effects on target crops.

[0280] Example 65: Efficacy test of a mixture of flubendiamide and active ingredient B for controlling rice planthoppers.

[0281] Test agents and field treatments: The test agents and dosages are shown in Table 5; each treatment was repeated 4 times.

[0282] Test Methods: The experimental plots were arranged in randomized blocks, with four replicates per treatment. The parallel jump method was used to investigate the efficacy of the pesticide. Ten sites were surveyed per plot, with two rice clumps surveyed at each site. The rice clumps were patted or shaken, and the number of planthoppers floating on the water between the rice clumps was counted. The base population was surveyed before application, and the number of remaining planthoppers was surveyed 3, 7, and 14 days after application. The planthopper counts before and after application were used to calculate the population reduction rate and control efficacy of each treatment.

[0283] Data Analysis:

[0284] Pest reduction rate (%) = (pest population before treatment - pest population after treatment) / pest population before treatment × 100

[0285] Corrected control efficacy % = (insect population reduction rate in treated area - insect population reduction rate in control area) × 100 / (100 - insect population reduction rate in control area)

[0286] Table 5 Results of efficacy test on the mixture of flubendiamide and active ingredient B for controlling rice planthoppers

[0291] Test method: Mark 10 eggplant plants in each plot and investigate the base number of thrips before spraying; investigate the number of thrips remaining on each plant 1 day, 3 days, and 7 days after spraying.

[0292] Calculation method of drug efficacy:

[0293] Pest reduction rate (%) = (pest population before treatment - pest population after treatment) / pest population before treatment

[0294] ×100

[0295] Corrected control efficacy % = (insect population reduction rate in the treated area - insect population reduction rate in the control area) / (100 - insect population reduction rate in the control area) × 100

Within the test range, the drug demonstrated no adverse effects on target crops.

[0301] Example 67: Efficacy test of a mixture of flubendiamide and active ingredient B for controlling apple and peach borer.

[0302] Experimental agents and field design: The experimental agents and dosages are shown in Table 7. Each treatment was replicated 4 times.

[0303] Application time and method: The experiment was carried out on June 1, 2018 at the Hailier Laixi test base with a one-time application of pesticides.

[0304] Survey Method: Survey two fruit-bearing trees per plot. Inspect 200 fruits around the crown and in the middle and upper parts of each tree, recording the number of fruit with eggs and insects, and calculating control effectiveness. Survey the base number before application and again six and 12 days after application. Also observe whether the pesticide has harmed the apple trees.

[0305] Calculation method of drug efficacy:

[0306] Control effect % = ((number of newly infested fruits in the control area - number of newly infested fruits in the treatment area) / number of newly infested fruits in the control area) × 100

[0307] Test results: See Table 7.

[0308] Table 7 Results of efficacy test of flubendiamide mixed with active ingredient B against apple and peach borer

[0309]

[0310]

[0311] As shown in Table 7, the combination of flufenacet and active ingredient B effectively controls apple and peach borer. Six days after application, the control efficacy was above 80%, exceeding that of either agent alone. Twelve days after application, the control efficacy was above 85%, significantly exceeding that of either agent alone. Field efficacy demonstrated that the combination of flufenacet and active ingredient B was more effective against apple and peach borer than either agent alone, with a longer-lasting effect. Within the test range, the combination had no adverse effects on target crops.
