Problems solved by technology

Although methoxyacrylate fungicides have a good bactericidal effect, the current production and use costs are relatively high
In addition, long-term single use will also have a great risk of resistance
At present, there is no relevant report on the compounding of penconazole and methoxyacrylate fungicides

example 1

[0029] Bioassay example 1: Toxicity determination of penconazole combined with trifloxystrobin, kysstrobin, pyraclostrobin or fluoxastrobin against cucumber powdery mildew

[0030] Test object: Cucumber powdery mildew (Sphaerotheca fuliginea)

[0031] The potted method was used in this experiment. Sowing cucumber powdery mildew-sensitive varieties, take cucumber seedlings that have grown to 2 true leaf stages, and treat 5 pots for each treatment, and number them for later use. On the basis of the preliminary test, set 5-7 series of mass concentrations according to the activity of the drug. Spray the liquid medicine evenly on the leaf surface until it is completely moistened, and wait for the liquid medicine to dry naturally for later use. And the treatment containing only solvent and surfactant but no active ingredient was set as blank control. 24 hours after the application, the powdery mildew spore suspension was inoculated. The preparation method of the spore suspension...

[0062] Bioassay Example 2: Toxicity determination of penconazole combined with azoxystrobin, kresoxim-methyl or picoxystrobin against rice blast

[0063] Test object: rice blast fungus (Pyricularia oryzae Cav)

[0064] In this experiment, the potted method was adopted, and the seeds of rice blast-susceptible varieties were selected. After accelerated germination, 20 seeds were sown in each pot, and when they grew to the stage of 3 leaves and 1 heart, the rice seedlings with the same growth were selected and numbered for later use. According to the drug activity, set 5-7 serial mass concentrations. Spray the liquid medicine evenly on the leaf surface until it is completely wet, and wait for the liquid medicine to dry naturally for later use. 5 pots were treated for each treatment, and the treatment containing only solvent and surfactant but no active ingredient was set as a blank control. After 24 hours of chemical treatment, the inoculated spore suspension was evenly sprayed...

example 3

[0084] Bioassay example 3: Toxicity determination of the combination of penconazole and pyraclostrobin or oxastrobin against gray mold of cucumber

[0085] Test object: Cucumber Botrytis cinerea Pers.

[0086] The potted method was used in this experiment. Cucumber gray mold susceptible to sowing varieties, grown in pots to the stage of 2 true leaves, numbered for later use. On the basis of the preliminary test, set 5-7 series of mass concentrations according to the activity of the drug. For each treatment of 4 pots, spray 10ml of the medicinal solution evenly on the leaves until they are completely wet, and wait for the medicinal solution to dry naturally for later use. And the treatment containing only solvent and surfactant but no active ingredient was set as blank control. After 24 hours of chemical treatment, a crop sprayer was used to evenly spray and inoculate the conidia suspension of Botrytis cinerea on cucumber leaves. The preparation process of the conidia suspe...

Abstract

The invention relates to a sterilizing composition. Effective components of the sterilizing composition include penconazole (A) and a methoxyl acrylates bacteriostat (B) which is kresoxim-methyl, azoxystrobin, pyraclostrobin, metominostrobin, trifloxystrobin, picoxystrobin, picoxystrobin, fluoxastrobin, enestroburin, kresoxim-phenmethyl or SYP, wherein the mass ratio of A and B is 50:1-1:50. The mixing of A and B has obvious synergistic function and is used for preventing and killing diseases of fruit trees, cotton, wheat, rice, colza, vegetables, flowers and other plants, particularly for preventing and killing fungoid diseases.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a compound bactericidal composition containing a methoxyacrylate bactericide and penconazole. Background technique [0002] Triazoles have played an important role in the control of powdery mildew, scab, white rot, rice blast, gray mold and other diseases. However, the ensuing pathogenic bacteria resistance problem is becoming more and more prominent. The resulting frequent application of pesticides has caused increased burden on farmers and increased environmental pollution. In addition, triazole agents can inhibit the growth of crops, and there are potential safety concerns in use. [0003] Penconazole, English common name Penconazole, chemical name 1-[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolane-2-methyl]-1-hydrogen -1,2,4-triazole is a relatively new triazole fungicide, which inhibits or interferes with the development of spores and haustoria and the growth of mycelium by inh...
