Complex bactericide for mainly treating grey mould disease, early blight and powdery mildew

Abstract

The invention relates to a pesticide, in particular to a complex bactericide for mainly treating grey mould disease, early blight and powdery mildew, which is used for preventing and controlling the grey mould disease, early blight, powdery mildew, downy mildew and late blight of vegetable and fruit crops. The complex bactericide consists of active ingredients, a filler and/or an auxiliary agent, wherein the active ingredients consist of boscalid and methoxyl acrylate bactericide in the weight ratio of 1-100:1-100. The complex bactericide can also be prepared into wettable powder or water dispersible granules for use. The complex bactericide has the advantages of high quick acting performance, novel action mechanism and capability of effectively suppressing and delaying the occurrence and development of germ resistance to the medicament; and a preparation process has the advantages of simplicity, low cost, wide disease prevention spectrum and high biological safety.

Description

technical field [0001] The invention relates to a pesticide, in particular to a compound fungicide for mainly treating gray mold, early blight and powdery mildew, which is used for preventing and treating gray mold, early blight, powdery mildew, downy mildew and late blight of fruits and vegetables. Background technique [0002] Botrytis cinerea, early blight, powdery mildew, downy mildew and late blight are all common crop diseases of fruit and vegetable crops, and their pathogenic bacteria have a great impact on fruit and vegetable crops and cause serious harm. At present, the medicaments for the prevention and treatment of the above-mentioned crop diseases can be mainly classified as follows: [0003] Protective fungicides: such as mancozeb, thiram, chlorothalonil, etc. These agents have a broad bactericidal spectrum and a wide range of applications, but these agents not only cannot effectively protect new branches and leaves, but also have a general control effect . ...
