Embodiment 1

[0057] Weigh 30% syringstrobin, 50% dimethomorph, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 3% pull open powder BX (sodium dibutylnaphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% diatomite, 5% glucose, and kaolin are added to 100% by weight. 80% syringstrobin·dimethomorph water-dispersible granules are prepared by the conventional method for preparing water-dispersible granules from the above-mentioned raw materials, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

[0058] The formula is used to prevent and control cucumber downy mildew. The dosage per mu is 10g, diluted with 50kg of water and sprayed, and the control effect is 92.5% after 7 days of application. The dosage per mu of 20% syringstrobin suspension concentrate is 20g and that of 50% dimethomorph water dispersible granule is 40g per mu. Using the same method, the control effects after...

Embodiment 2

[0060] Weigh 10% syringstrobin, 40% metalaxyl, 3% TERSPERSE 2700, 3% diffusing agent NNO, 2% pull open powder BX, 1% K-12, 1% carboxymethylcellulose, 3% urea, Diatomaceous earth is added to 100% by weight. 50% syringstrobin·metalaxyl water dispersible granules were prepared by the conventional method for preparing water dispersible granules from the above raw materials, that is, mixing, ultrafine airflow pulverization, mixing and granulation.

[0061] The formula is used to prevent and control grape downy mildew. It is diluted with water 2500 times and sprayed, and the control effect is 91.1% 10 days after application. 20% syringstrobin suspensible concentrate was used at 2000 times and 20% metalaxyl wettable powder was used at 500 times by the same method, and the control effects were 78.5% and 76.4% respectively 10 days after the drug.

Embodiment 3

[0063] Weigh 20% syringstrobin, 10% metalaxyl, 4% TERSPERSE 2700, 2% diffusing agent NNO, 2% pull open powder BX, 2% K-12, 3% corn starch, 5% ammonium sulfate, concave-convex Rod clay is added to 100% by weight. 30% syringstrobin-methylaxyl water-dispersible granules were prepared from the above-mentioned raw materials through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

[0064]The formula is used to prevent and treat pepper blight, the dosage per mu is 15g, diluted with 50kg of water and sprayed, and the control effect is 92.5% after 10 days of application. The dosage of 20% syringstrobin suspending agent per mu is 20g and that of 10% metalaxyl WP is 50g per mu. Using the same method, the control effects after 10 days of application are 78.2% and 82.6% respectively.

Abstract

The invention discloses a germicide composition containing coumoxystrobin, which comprises effective active ingredients consisting of a first active ingredient and a second active ingredient, wherein the first active ingredient is coumoxystrobin, the second active ingredient is a bactericide preventing and treating oomycete diseases and selected from dimethomorph, metalaxyl, metalaxyl-M, benalaxyl, propamocarb, fosetyl aluminium, cymoxanil, cyazofamid or fluopicolide, and the weight ratio of the first active ingredient to the second active ingredient is 1:20-20:1. The composition can be prepared into water dispersible granules, wettable powder, suspending agents and flowable concentrates for seed coating permitted in agriculture. The composition disclosed by the invention has reasonable components, a good bactericidal effect and low medication cost, and the activity and the bactericidal effect of the composition are not the simple sum of the activity of each component. Compared with the existing single preparation, the composition also has an obvious synergistic effect in addition to an obvious sterilizing effect, the generation of resistance is retarded, the residual quantity of the preparation is small, and the composition has no pollution on crops, has good safety and meets the requirement on the safety of the pesticide preparation. The germicide composition disclosed by the invention has obvious prevention and treatment effects on vegetable downy mildew, vegetable epidemics, vegetable and cotton seedling damping off, fruit tree downy mildew and peronophythora litchii.

Description

technical field [0001] The invention relates to a fungicidal composition containing syringstrobin and belongs to the technical field of compound pesticides. Background technique [0002] Methoxyacrylic fungicides are newly developed fungicide varieties in recent years and are a major milestone in the field of fungicides. Methoxyacrylate fungicides have a unique mechanism of action, which prevents ATP synthesis in cells by locking the electron transfer between cytochrome b and c1, thereby inhibiting mitochondrial respiration and exerting antibacterial effects. Effective against strains resistant to 14-demethylase inhibitors, benzamides, dicarboxamides and benzimidazoles. It has protection, treatment, eradication, penetration and systemic activities, and can degrade quickly in plants, soil and water. Although this type of fungicide has a unique mechanism of action, the pathogenic bacteria develop resistance to it very quickly, and the cost of use is high, which limits the la...
