Compound pesticide of chlorantraniliprole and chlorpyrifos

Abstract

The invention belongs to the technical field of compound pesticides, and particularly relates to a compound pesticide of chlorantraniliprole and chlorpyrifos. The compound pesticide is compounded reasonably according to respective characteristics of the chlorantraniliprole and the chlorpyrifos, a combination ratio with obvious synergic action is screened out through a series of indoor biological tests and field experiments, and the compound pesticide comprises the following components in percentage by weight: 0.5 to 2.5 percent of the chlorantraniliprole, and 32.5 to 35 percent of the chlorpyrifos. The compound pesticide of the chlorantraniliprole and the chlorpyrifos has the optimal cooperative and synergistic action, has the co-toxicity coefficient to chilo suppressalis of 310.4 to 518.0, has the advantages of wide insecticidal spectrum, quick response and good lasting effect, greatly reduces the production and using costs of the pesticide, reduces the cost per acre by about 30 to 40 percent compared with that of the single use of the chlorantraniliprole, has good effects of controlling rice insect pests such as the chilo suppressalis, brown planthoppers, cnaphalocrocis medinalis and the like, and has no untoward effect on the growth development of rice.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, in particular to a compound pesticide of chlorantraniliprole and chlorpyrifos. Background technique [0002] Rice is the main variety of food crops in my country. It has a large planting area, with an annual planting area of ​​about 400 million mu. There are many types of diseases, insects, and weeds. According to the statistics of the agricultural department, the output is lost every year due to diseases, insects, and weeds. Greater than 20-30%. The amount of pesticides used to prevent and control rice diseases, insects, and weeds accounts for about 50% of the annual use of pesticides in my country. The main pests that harm rice, as far as the national rice planting areas are concerned, the main pests are the rice borer, rice planthopper, rice leaf roller, etc., and the annual occurrence area is about 1 billion mu, and the area of ​​pesticide control reaches 1 billion to 1.2 billion ...

AI Technical Summary

Problems solved by technology

[0008] The practice of chlorantraniliprole in the control of rice pests shows that it is effective against young larvae of Lepidoptera pests, poorly against older larvae, and ineffective against other types of pests, such as rice planthoppers

At the same time, the cost of medication is very high. For 20% chlorantraniliprole gel suspension (Kangkuan), 10 grams of medication per mu costs about 16 yuan.
