Example Embodiment

[0056] Example 1

[0057] Weigh 30% syringomycin, 50% dimethomorph, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), Add 3% BX (sodium dibutyl naphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% diatomaceous earth, 5% glucose, and kaolin to 100% by weight. The above-mentioned raw materials are prepared by conventional methods for preparing water dispersible granules, namely mixing, ultra-fine jet pulverization, mixing, and granulation steps to prepare 80% syringomycin·dimethomorph water dispersible granules.

[0058] The formula is used to prevent and treat cucumber downy mildew. The dosage is 10g per mu, and the spray is diluted with 50kg of water. The control effect is 92.5% 7 days after the medicine. The dosage of 20% syringomycin suspension is 20g per mu and the dosage of 50% dimethomorph water dispersible granules is 40g per mu. Using the same method, the control effect of 7 d...

Example Embodiment

[0059] Example 2

[0060] Weigh 10% syringomycin, 40% metalaxyl, 3% TERSPERSE 2700, 3% diffusing agent NNO, 2% powder BX, 1% K-12, 1% carboxymethyl cellulose, 3% urea, The diatomaceous earth is added to 100% by weight. The above-mentioned raw materials are prepared by conventional methods for preparing water-dispersible granules, namely mixing, ultra-fine jet pulverization, mixing, and granulation steps to prepare 50% syringosin-methyl-metalaxyl water-dispersible granules.

[0061] This formula is used to prevent and treat grape downy mildew. It is diluted and sprayed with water by 2500 times, and the control effect is 91.1% after 10 days. The 20% syringomycin suspension is 2000 times and the 20% metalaxyl wettable powder is 500 times, using the same method, the control effect is 78.5% and 76.4% 10 days after the medicine.

Example Embodiment

[0062] Example 3

[0063] Weigh 20% syringomycin, 10% metalaxyl, 4% TERSPERSE 2700, 2% diffusing agent NNO, 2% spreading powder BX, 2% K-12, 3% corn starch, 5% ammonium sulfate, bump The clay is added to 100% by weight. The above-mentioned raw materials are prepared by conventional methods for preparing water-dispersible granules, namely mixing, ultra-fine jet pulverization, mixing, and granulation steps to prepare 30% syringomycin·methoxalin water-dispersible granules.

[0064] The formula is used to control pepper blight. The dosage is 15g per mu, and the spray is diluted with 50kg water. The control effect is 92.5% 10 days after the medicine. The dosage of 20% syringomycin suspension is 20g per mu and the dosage of 10% metalaxyl wettable powder is 50g per mu. Using the same method, the control effect of 10 days after administration is 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...
