Problems solved by technology

Agricultural control refers to the promotion of disease-resistant cotton varieties. However, in recent years, there are many types of spider mites that damage cotton, and the changes are rapid and diverse. Generally, disease-resistant cotton varieties will lose their disease resistance within a few years after promotion. In addition, there are certain contradictions between disease-resistant varieties and high-yield, high-quality traits, and the area of ​​biological control is still very small, so the production is still dominated by chemical control
In agricultural production, attention should be paid to the application of pesticides that have both effects on spider mite. Some existing products have developed resistance, and some have been eliminated due to other reasons. Therefore, according to the occurrence and control of cotton diseases, it is necessary to develop high-efficiency, broad-spectrum pesticides. , low toxicity, safety, delayed resistance, long service life and effective against spider mite new insecticide

Abstract

The invention discloses an insecticidal compound agent for preventing and curing cotton red spiders, comprising the effective components of diafenthiuron and biphenthrin with the weight ratio of 1-5 to 1 and the preferable weight ratio of 2-4 to 1. After the two effective components are compounded, the insecticidal compound agent has the advantages of perfect efficacy, good durability, obvious synergism, safety to cotton, simple using and low cost and is a novel effective insecticide for killing cotton red spiders.

Description

technical field [0001] The invention relates to an insecticidal pesticide, in particular to a compounded insecticidal pesticide. Background technique [0002] Cotton spider mites are a type of pest that commonly occurs in cotton areas in various parts of my country and cause serious damage. Cotton spider mites mainly suck nutrient juice on the back of cotton leaves. At the beginning of the damage, there are many white spots on the front of the leaves. After a few days, the petioles turn red. In severe cases, the leaves will fall and the stalks will collapse, which looks like a fire, resulting in a large area of ​​reduced or no harvest. [0003] At present, the control of cotton spider mites in agricultural production is mainly based on agricultural control, biological control and chemical control. Agricultural control refers to the promotion of disease-resistant cotton varieties. However, in recent years, due to the large number of species of spider mites that damage cotton ...
