Problems solved by technology

The drug has no knockdown activity and will not cause direct toxicity to insects, but once the insects come into contact with the drug, they will immediately block the stylet and stop feeding, and eventually starve to death, and this process is irreversible

Abstract

The invention relates to a pesticide composition which is characterized by containing MTMC and pymetrozine with increased effect and effective dose, wherein preference of the weight ratio of the MTMC and the pymetrozine is 50:1 to 1:10; the better preference is 20:1 to 1:10; the specially better preference is 15:1 to 1:1; and the best preference is 11:1 to 1:1. The pesticide composition can be used for preparing dosage forms of missible oil, microemulsion agents, wettable powder agents, water dispersible granules agents, granular agents or suspending agents according to methods known by technicists in the technical field.

Description

technical field [0001] The invention relates to a synergistic pesticide composition, in particular to a synergistic pesticide composition containing amecarb and pymetrozine. Background technique [0002] Metolcarb (metolcarb) belongs to a certain selective fast-acting substituted benzene carbamate insecticide, which has contact killing and fumigation effects on pests, and also has a certain systemic effect. The mechanism of action is to inhibit acetylcholinesterase, causing insects Paralyzed to death. The drug has strong knockdown power and short duration of effect, usually only 3-4 days. It is mainly used to control rice planthoppers and black-tailed leafhoppers that are resistant to malathion, and has good control effects on both adults and nymphs. With good quick effect, it can also be used to control rice leaf roller, tea tree aphid, small green leafhopper, landrace and tortoise shell insect, first-instar nymph of whitefly, citrus gall mite, cotton aphid, cotton bollwo...
