Abstract

The invention provides a fenoxycarb insecticidal composition, which comprises fenoxycarb and a second insecticidal ingredient; wherein the weight ratio of fenoxycarb to second insecticidal ingredient is 80: 1-1: 80, and the second insecticidal ingredient is preferably thiamethoxam, or emamectin benzoate, or a combination of thiamethoxam and emamectin benzoate. The provided fenoxycarb insecticidal composition has the advantages that the synergy effect is obvious, LC50 can be obviously reduced, pesticide amount is reduced, and the insecticidal composition has characteristics of wide insecticidal spectrum, high efficiency, low toxicity, low prevention and treatment cost.

Description

technical field [0001] The invention relates to an insecticide, in particular to an insecticidal composition containing fenoxycarb. Background technique [0002] The insecticidal mechanism of traditional pesticides is generally poisonous, with high toxicity and poor safety. At present, organophosphorus pesticides are gradually being banned and restricted, and pyrethroid pesticides are gradually declining in market share due to resistance problems. [0003] Insect growth regulators can disrupt the normal growth and development of insects, reduce the viability and death of individual insects, thereby achieving the purpose of preventing pests and protecting crops. They have the characteristics of low toxicity, low pollution, and safety for humans, animals and beneficial insects. Among them, fenoxycarb ([2-(4-phenoxy-phenoxy)ethyl] ethyl carbamate, Fenoxycarb) is a non-terpene carbamate compound, which has stomach toxicity and Juvenile hormone insecticides with contact killing ...
