Problems solved by technology

[0005] Grape downy mildew is one of the most serious diseases of grape leaves. When the disease is severe, the diseased leaves are scorched and fall early, and sometimes even the leaves of the vineyard are damaged and fall off, which can lead to poor growth of new shoots, difficulty in fruit development and ripening, and a serious decline in yield.

Embodiment Construction

[0020] The present invention is illustrated by the following specific implementation examples, but is not limited to these examples. Percentages in all formulations are by weight.

[0021] 1. Composition preparation

[0022] (1) Preparation of suspoemulsion

[0023] A. Prepare acetoallicin water emulsion first, add acetoallicin to emulsifier and other additives, stir evenly, add to water phase, use high-shear emulsifier to cut evenly, and then set aside. B. Add dikestrobin, wetting and dispersing agent, thickener, preservative, antifreeze, and water according to the ratio, use a high-speed shearing machine to cut evenly, put it into the dispersion disc of the sand mill, and sand it to the particle size The diameter is below 5 microns, and the finished suspension concentrate is obtained. C. After mixing A and B in proportion, shear evenly to obtain a suspoemulsion.

[0024] Formulation example 1: 12% dikestrobin, 36% ethyl allicin, 2% rosin grafted EO-PO block copolymer, 3%...

Abstract

The invention discloses a bactericidal composition containing dikestrobin and acetostrobin. The film component is 0.5%-15%, and the rest are additives and water, and the percentage concentration is weight percentage. The fungicidal composition has a technically feasible composition ratio, and shows a good synergistic effect on the prevention and treatment of grape downy mildew, and can effectively reduce the risk of resistance of grape downy mildew to dikestribin , is an ideal grape fungicide composition.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a bactericidal composition containing dikestrobin and acetoallin. technical background [0002] Dikestrobin (test code ZJ0712), a new type of methoxyacrylate fungicide, is a new type of fungicide with high efficiency, low toxicity and low residue created by the Zhejiang Base of the National Southern Pesticide Innovation Center (namely Zhejiang Research Institute of Chemical Industry) . A large number of laboratory and field efficacy tests of this product have shown that it is effective against powdery mildew (such as melon powdery mildew, apple powdery mildew, etc.), rust (such as apple rust, pear rust, etc.), downy mildew (grape and Cucumber downy mildew, etc.), anthracnose (such as cucumber, watermelon and mango anthracnose, etc.) all show excellent control effects, have the advantages of broad bactericidal spectrum and high activity, and have protective and therapeutic e...
