Sterilization composition

Abstract

The invention relates to a bactericidal composite which takes diacetone amine copper and cymoxanil as effective components. The mass percentages of the two effective components are: 1 to 60 percent of the diacetone amine copper and 1 to 40 percent of the cymoxanil; the weight ratio of the two effective components is equal to 1 to 5 : 1. The composite can be processed into a wettable powder and a deflocculant and has good control effects on vegetable diseases of cucumber downy mildew, etc. The composite is characterized by simple production technology, low control cost, being safe for crops and environment, etc.

Description

Technical field The invention belongs to the technical field of pesticides, and particularly relates to a bactericidal composition using copper diacetoneamine and cymoxanil as effective ingredients. Background technique In recent years, with the increase in the planting area of ​​fruit trees and vegetables in my country, especially the large-scale promotion of vegetable cultivation techniques in protected areas, the incidence and incidence of crop diseases have increased significantly. Apple rot disease and early leaf fall disease are characterized by a high incidence and mass-occurrence in most areas of our country. The direct consequences of the disease are less severe, resulting in a reduction in production, and the more severe can cause damage to the garden. Vegetable diseases such as cucumber downy mildew and tomato blight have become the number one killer in vegetable cultivation in protected areas, often causing rotten leaves, rotten fruits, and even death of the whole pla...

Problems solved by technology

The frequent occurrence of diseases makes the frequency of use of fungicides increase continuously, and the high frequency of application makes the bacteria more and more resistant, thus causing a vicious circle

Organic synthetic fungicides have high activity, rapid action, and most of them have the characteristics of therapeutic effect. They often achieve better control effect in the early stage of use, but the disadvantage is that bacteria are easy to develop resistance to them.

Inorganic fungicides, such as copper preparations, are the earliest fungicides and one of the longest-used fungicides. Accumulation in plants, thus causing phytotoxicity to crops, and most of them only have protective effect, but poor therapeutic effect
