Problems solved by technology

[0007] At present, due to the long-term use of a single agent, it is easy to cause resistance to plant diseases and the purpose of treatment cannot be achieved. The use of a compound fungicidal composition can effectively delay the development of disease resistance and reduce the frequency and amount of pesticide use. It has become a comprehensive important means of disease control
[0008] No one has reported the compound bactericidal composition containing bromothalonil and prochloraz at present

Abstract

The invention relates to a bactericidal composition containing bromothalonil and prochloraz, wherein the weight percentage of the bromothalonil to the prochloraz is 1-40:1-30. The bromothalonil and the prochloraz have obvious synergistic action and persistent effects after compounding and are mainly used for controlling anthracnosis on fruit trees and vegetables. The composition has the advantages of high efficiency, low toxicity, low pollution and low residue, remarkably reduces the usage amount and the usage times of medicaments, reduces the cost, slows down the drug resistance of diseases,and is suitable for large-scale popularization and use.

Description

Technical field: [0001] The invention belongs to the technical field of pesticide sterilization, and in particular relates to a bactericidal composition compounded of bromothalonil and prochloraz, which is used for preventing and treating anthracnose of fruit trees and vegetables. technical background: [0002] Bromothalonil, the English name is (bromothalonil), the chemical name is 2-bromo-2 bromomethylglutaronitrile, and the structural formula is: [0003] [0004] Bromothalonil technical is a low-toxic fungicide according to the Chinese classification standard of pesticide toxicity. Effective against anthrax. Widely applicable to fruit trees, grapes, vegetables, cotton, peanuts, watermelon, tobacco, tea trees, flowers and other crops, to prevent and control anthracnose, scab, scab, powdery mildew, rust, blight, damping-off, rhizome Rot, canker, bacterial wilt, angular spot and other fungal and bacterial diseases. The application method is flexible, and foliar spray,...
