Problems solved by technology

[0005] Fluoramide is mainly used to prevent and control crop diseases caused by basidiomycete pathogens. The bactericidal spectrum is relatively narrow, and it has good systemic and therapeutic effects. Due to the high price of this product, there are not many single-dose applications, and the marketization is not ideal.

Abstract

The invention relates to a bactericidal composition containing prochloraz and flutolanil and application thereof. The weight ratio of the prochloraz to the flutolanil is 2-40:3-60. The composition can be applied to disease control of cereal crops, melons, fruits or vegetables and other crops. The bactericidal composition containing prochloraz and flutolanil is wide in application range, good in effect, low in cost, low in residuals and safe to users, livestock, environment and the like.

Description

(1) Technical field [0001] The present invention relates to a bactericidal composition and its use, in particular to a bactericidal composition containing prochloraz and fluoroamide, which is mainly used for the prevention and treatment of cereal crop diseases. (2) Background technology [0002] In recent years, due to single and unscientific drug use, many crop diseases have become resistant to the currently used pesticides, such as powdery mildew, rice blast, gray mold, anthracnose, etc., which have become one of the most difficult problems in chemical control. one. At the same time, the increase in the frequency and dosage of medication not only increases the burden on farmers, but also affects food and environmental security. [0003] Prochloraz is a high-efficiency, broad-spectrum, low-toxic fungicide with multiple functions such as systemic conduction, prevention, protection and treatment. It works by inhibiting the biosynthesis of sterols, and has systemic conduction...
