Problems solved by technology

However, long-term continuous application of a single variety of fungicides or unscientific use of pesticides has led to increasingly serious disease resistance; at the same time, due to excessive use of pesticides, it has led to problems such as environmental pollution and increased pesticide costs for farmers, which is not conducive to the sustainable development of agriculture.

Embodiment 1

[0033] Weigh 10% valerocin, 10% pyraclostrobin, 4% alkylphenol polyoxyethylene ether phosphate, 3% phenethylphenol polyoxyethylene ether phosphate, 5% sodium alkyl sulfate, 0.5% carboxyethyl cellulose, 3% polyethylene glycol, 0.4% methyl sorbate, 2% octanol, and deionized water are added to 100% by weight. The above raw materials are mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to a particle size of D 90 A 20% suspension concentrate of valerosamine pyraclostrobin was prepared after the micron was less than 10 microns.

Embodiment 2

[0035] Weigh 2% Valilecin, 3% Dimethomorph, 2% Lauryl Polyoxyethylene Ether Phosphate, 3% Sodium Lignosulfonate, 2% Alkylphenol Formaldehyde Resin Polyoxyethylene Ether, 1.5% Bentonite, 2% urea, 0.3% potassium sorbate, 1% hexanol, and deionized water are added to 100% by weight. The above raw materials were mixed and dispersed by high-speed shearing for 30 minutes, and then sanded with a sand mill to a particle size of D 90 After the micron is less than 10 microns, a 5% suspension concentrate of dimethomorph can be prepared.

Embodiment 3

[0037] Weigh 8% valilecin, 40% iprodione, 3% polycarboxylate, 5% sodium lignosulfonate, 3% alkylnaphthalene sulfonate, 0.5% xanthan gum, 5% propylene glycol, 0.3% Potassium sorbate, 1% hexanol, and deionized water are added to 100% by weight. The above raw materials were mixed and dispersed by high-speed shearing for 30 minutes, and then sanded with a sand mill to a particle size of D 90 After less than 10 microns, a 48% Valeroxan·Iprodione suspension was prepared.

Abstract

The invention belongs to the field of pesticides and relates to a bactericidal composition containing valifenalate. The bactericidal composition containing valifenalate comprises an active ingredientA and an active ingredient B at a ratio of parts by weight of 1:30-30:1, wherein the active ingredient A is valifenalate; and the active ingredient B is pyraclostrobin, dimethomorph, iprodione or propamocarb. The invention provides the bactericidal composition containing valifenalate and the application of the bactericidal composition. The bactericidal composition is efficient, low in toxicity andlong in lasting period, and can reduce generation of pesticide resistance of diseases, and a dose can be reduced.

Description

technical field [0001] The invention belongs to the field of pesticides, and relates to a bactericidal composition containing valhexamine, in particular to a bactericidal composition containing valhexamine for preventing and treating downy mildew and an application thereof. Background technique [0002] Valifenal, the English name is Valifenalate, the chemical name is N-(isopropoxycarbonyl)-L-valyl-(3RS)-3-(4-chlorophenyl)-R-alanine methyl ester, It belongs to amino acid derivatives, has strong systemic activity, and has high biological activity against plant diseases caused by oomycetes. It mainly plays the role of protection, treatment and eradication on the surface and body of plants. [0003] Pyraclostrobin, the English name is Pyraclostrobin, the chemical name is methyl (N)-[[1-(4-chlorophenyl)pyrazol-3 base)-oxygen]-0-methoxy]-N-methyl Oxyurethane. The compound is a new broad-spectrum fungicide of methoxyacrylate developed by BASF, and has the functions of protection...
