Abstract

The invention relates to a high-efficiency and low-toxic compound insecticidal composition containing lufenuron and its application. The insecticidal composition is composed of lufenuron, acetamiprid, auxiliary agents and excipients respectively, and is formulated into an emulsifiable concentrate, wherein the weight percentage of lufenuron and acetamiprid is 0.1-30:0.5-60. The insecticidal composition can produce relatively high synergistic effect, overcome and delay the resistance of pests, expand the spectrum of control, have high insecticidal speed, reduce the cost of medication, and reduce toxicity. The invention can prevent and control homopteran pests occurring on crops, especially can be used for preventing and controlling wheat aphids, and its effect is obviously higher than that of a single agent.

Description

technical field [0001] The invention relates to an insecticidal composition and its application, in particular to an insecticidal composition with lufenuron and acetamiprid 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 ...
