Insecticide composition containing spinetoram

Abstract

The invention discloses an insecticide composition containing spinetoram and belongs to the technical field of injurious insect chemical prevention. The effective component A is spinetoram and the effective component B is one of silafluofen, wherein a weight ratio of the component A to the component B is 1: 20 to 20: 1; in addition to the effective components, the insecticide composition further comprises auxiliaries and filler, wherein the effective components A and B account for 15-50% of the total weight of the insecticide, the auxiliaries account for 20-30% of the total weight of the insecticide, and the balance is the filler. The insecticide composition can be prepared into wettable powder, suspending agents and the like. The insecticide composition disclosed by the invention has relatively good preventing and treating effect on rice planthopper, aphids, vegetable bemisia tabaci, cnephalocrocis medinalis, stem borers and the like. Compared with a conventional preventing and treating agent, the dosage can be reduced, the environmental pollution can be reduced, and the residue of agricultural products can be reduced. The drug resistance of a single insecticide can be delayed, the insecticide composition has the advantage of being long in lasting period. Compared with a single preparation, the cost can be lowered.

Description

technical field [0001] The invention belongs to the technical field of pest chemical control, and relates to an insecticide composition containing spinosyn. Background technique [0002] There are many kinds of rice pests. The "two-migrating" pests (rice planthopper, leaf roller) are important pests in rice production, and rice planthoppers (brown planthopper, brown planthopper, and white-backed planthopper) are a kind of insect with strong migratory ability. (Except for SBPH), rice pests with extremely fast reproduction speed, causing the base of rice clusters to be dark brown, abnormal heading, and 1000-grain weight reduction. Leaf blight and black-streaked dwarf are one of the main pests of rice. For a long time, the control of rice planthoppers has mainly relied on imidacloprid, buprofezin, organophosphorus and their compounding agents. The use of highly toxic organophosphorus pesticides has been banned. Due to long-term single and continuous use, brown planthoppers and...

AI Technical Summary

Problems solved by technology

Spinosad has a good control effect on leaf rollers, but the speed of action is slow and the cost per mu is high. The combination of ethyl spinosad and flusalthrin uses different mechanisms of action to take into account the two kinds of pests. It can effectively control rice planthoppers and leaf rollers, and it is a comprehensive pest resistant pesticide variety
