Abstract

A synergistic composite insecticide for preventing and treating rice borer and beet noctuid contains iurfenuron, chlorpyrifos, assistant and excipient.

Description

technical field [0001] The invention relates to an insecticidal composition and its application, in particular to an insecticidal composition with lufenuron and chlorpyrifos as main active ingredients and its application. Background technique [0002] Lufenuron (Lufenuron), chemical name: N-[[[2,5-dichloro-4-(1,1,2,3,3,3-hexafluoropropoxy)phenyl]amino]carboxyl]- 2,6-Difluorobenzamide. It is developed by the Swiss company Syngenta, CAS: 103055-07-8, and its 5% emulsifiable oil product is called Meiqu. [0003] Lufenuron is a benzoylurea acaricide and insecticide, an insect growth regulator, and an inhibitor of chitin synthesis. It is mainly used to control beet armyworm, Spodoptera litura, Cabbage armyworm, Diamondback moth, Cotton bollworm, Bean pod borer, Melon silk borer, Tobacco budworm, Thrips, Rust mites, Citrus leafminer, Planthopper, etc. It has stomach poisoning and contact killing effects, and has a unique insecticidal mechanism: it has good effects in inhibiting...
