Embodiment 1

[0061] 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.

[0062] 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

[0064] 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.

[0065] 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

[0067] 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.

[0068]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 coumoxystrobin-containing bactericidal composition. The active components are composed of a first active component coumoxystrobin and a second active component phosethyl-Al in a weight ratio of 1:20-20:1. The composition can be prepared into agriculturally accessible water-dispersible granules, wettable powder, suspending agents and suspended seed coatings. The invention has the advantages of reasonable components, favorable bactericidal effect and low reagent cost; and the activity and bactericidal effect of the composition are not simple superposition of activities of the components. Compared with the existing single preparation, the composition not only has obvious bactericidal effect, but also has obvious synergistic action. The composition decelerates the generation of resistance, has the advantages of low preparation residue level, no pollution for crops, and high safety, conforms to the safety requirements for pesticide preparations, and has obvious effect on preventing and treating downy mildew of vegetable, epidemic disease of vegetable, seedling-stage cataplexis of vegetable and cotton, downy mildew of fruit tree, and peronophythora.

Description

[0001] The patent application for the present invention is a divisional application of the following patents. [0002] Name of invention: a bactericidal composition containing syringstrobin; [0003] Application date of the original case: 20110831; [0004] Original application number: 201110253025.9. technical field [0005] The invention relates to a fungicidal composition containing syringstrobin and belongs to the technical field of compound pesticides. Background technique [0006] 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. I...
