Embodiment 1

[0037] Example 1: 50% pyraclostrobin·benzamid water dispersible granules (active ingredient ratio 1:1)

[0038] Weigh 25% pyraclostrobin original drug, 25% benzamid original drug, 4% NNO (alkyl naphthalene sulfonate formaldehyde condensate), 2% pull open powder BX (sodium dibutyl naphthalene sulfonate ), 2% K-12 (sodium lauryl sulfate), 15% ammonium sulfate, starch added to 100%. According to the proportion of the formula, the original drug, additives, fillers, etc. are mixed evenly, and the powder is obtained after jet crushing, mixed with a certain amount of water, granulated in a granulator, and then dried and sieved to obtain a granular product.

Embodiment 2

[0039] Example 2: 50% pyraclostrobin·benzamid water dispersible granules (active ingredient ratio 1:4)

[0040] Weigh 10% pyraclostrobin original drug, 40% benzamidr original drug, 3.5% NNO (alkyl naphthalene sulfonate formaldehyde condensate), 2.5% pull open powder BX (sodium dibutylnaphthalene sulfonate ), 3% K-12 (sodium lauryl sulfate), 15% ammonium sulfate, starch added to 100%. According to the proportion of the formula, the original drug, additives, fillers, etc. are mixed evenly, and the powder is obtained after jet crushing, mixed with a certain amount of water, granulated in a granulator, and then dried and sieved to obtain a granular product.

Embodiment 3

[0041] Example 3: 55% pyraclostrobin·benzamid water dispersible granules (active ingredient ratio 1:10)

[0042] Weigh 5% pyraclostrobin original drug, 50% benzamid original drug, 3.5% NNO (alkyl naphthalene sulfonate formaldehyde condensate), 2.5% pull open powder BX (sodium dibutyl naphthalene sulfonate ), 3% K-12 (sodium lauryl sulfate), 15% ammonium sulfate, starch added to 100%. According to the proportion of the formula, the original drug, additives, fillers, etc. are mixed evenly, and the powder is obtained after jet crushing, mixed with a certain amount of water, granulated in a granulator, and then dried and sieved to obtain a granular product.

Abstract

The invention relates to a sterilizing composition containing pyraclostrobin and zoxamide in a weight ratio of (100:1)-(1:100), and also relates to application of the sterilizing composition in plasmopara viticola. The sterilizing composition has an obvious synergetic effect to plasmopara viticola and the sterilizing effect is improved; the frequency of application can be effectively reduced, so that the cost of application can be reduced, and the environmental pollution and pesticide residue can be reduced; acting sites are increased, which is beneficial to overcoming and delaying of drug resistance of germs. The composition has no obvious adverse influence on tested crops, and the tested crops have normal leaf color and growing condition; the safety is high, and the safety requirement of pesticide preparations is met.

Description

technical field [0001] The invention relates to an agricultural composition and an agricultural fungicide, in particular to an agricultural composition and an agricultural fungicide for preventing and treating grape downy mildew. Background technique [0002] Grape downy mildew is a multi-cycle disease caused by the fungus Plasmopara viticola, and the number of propagules and propagators is the dominant factor for the occurrence and prevalence of the disease. Downy mildew poses a serious hazard to grape development and production. Due to the rapid propagation and spread of downy mildew, it is very destructive to the infected plants, often causing a decrease in yield and quality, resulting in important losses of crops. [0003] Zoxamide, CA name: 3,5-dichloro-N-(3-chloro-1-ethyl-1-methyl-2-oxopropyl)-methylbenzoic acid amine. Benzamid is a benzamide protective fungicide discovered by Rohm and Haas, with a novel mechanism of action. Benhexamid prevents nuclear division by b...
