Problems solved by technology

[0005] The long-term practical application shows that at present, many varieties of bactericidal products are used on wheat. Due to long-term use, the diseases on wheat have become resistant to pesticides, resulting in increased dosage, reduced control effect, shortened duration, and increased agricultural products and food. Safety risk, not conducive to environmental sustainable development

Abstract

The invention relates to a metconazole bactericide and application thereof. Active ingredients of the metconazole bactericide are metconazole and special emulsifier, wherein the weight ratio of metconazole to special emulsifier is 1:70 to 70:1, the weight content of metconazole in the bactericide is 10%, the special emulsifier is a mixture of a wetting agent and a dispersing agent, and the weight ratio of the wetting agent to the dispersing agent is 1:10 to 10:1. The metconazole bactericide is used for preparing pesticide preparations for preventing plant diseases, and particularly used for preparing pesticide preparations for controlling diseases of the same field including wheat rust, powdery mildew, gibberellic disease, damping off, bacterial blight and bacterial leaf stripe. Compared with the prior art, the metconazole bactericide is processed into a product by using a nanoscale rod type sanding machine through a special compound emulsifier, the product grain size is averagely 2 microns or below, it is judged according to effects of actual production application of 10% of metconazole bactericide, the pesticide effect is obviously improved, the pesticide use amount is reduced, per mu use amount against wheat rust is 20-30 g, and sterilization efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a metconazole fungicide and its application. Background technique [0002] Metconazole (Metconazole), chemical name: 5-(4-chlorophenyl)-2,2-dimethyl-1-(1,2,4-triazol-1-ylmethyl)-cyclopentene, CA registration number: 125116-23-6, molecular formula: C 17 h 22 ClN 3 O, structural formula: [0003] [0004] The mechanism and characteristics of metconazole: C-14 demethylase inhibitor in ergosterol biosynthesis. Although the mechanism of action is the same as other triazole fungicides, the activity spectrum is quite different. Both isomers have bactericidal activity, but the activity of the cis form is higher than that of the trans form. The fungicidal spectrum of metconazole is very broad and its activity is excellent. Compared with traditional fungicides, the dosage is extremely low and the range of cereal plant diseases is very wide. [0005] The long-term practical ap...
