Abstract

The invention belongs to the field of pesticide insecticidal/acaricidal compositions, in particular to a cyflumetofen-containing insecticidal/acaricidal composition. Aiming at the practical problems that the using amount of a pesticide is large, cost is high, the resistance of pests is easy to generate due to reuse, and the like in the conventional singly used propargite and pyridaben for preventing and controlling harmful acarids, the invention provides the cyflumetofen-containing insecticidal/acaricidal composition. The technical scheme is that: the cyflumetofen-containing insecticidal/acaricidal composition comprises active ingredients A and B, wherein A is cyflumetofen, and B is one of the pyridaben and the propargite. The insecticidal/acaricidal composition has the advantages that: after the cyflumetofen is compounded with the propargite or the pyridaben, the insecticidal/acaricidal composition has obvious synergy and persistent prevention and control effects; the using amount of the pesticide is reduced, the residual amount of the pesticide on crops is reduced, and environmental pollution is abated; and the insecticidal/acaricidal composition is safe for human and animals and has high environmental compatibility, and the pesticide resistance of the harmful acarids is difficult to generate.

Description

technical field [0001] The invention belongs to the field of pesticide insecticidal and acaricidal compositions, in particular to an insecticidal and acaricidal composition containing cyflumetate. Background technique [0002] Cyflumetofen, English name Cyflumetofen, trade name Danisraba, is a new type of acyl acetonitrile acaricide developed by Japan Otsuka Chemical Company, which has no cross-resistance with existing insecticides. In 2007, it was approved to be registered and sold in Japan for the first time. It is used for fruit trees, vegetables, tea trees and other crops and flowers to prevent and control the main mites that parasitize on plants. It is effective against eggs and adults of spider mites, and is more active against nymphs. [0003] Pyridaben, the chemical name is 2-tert-butyl-5-(4-tert-butylbenzylthio-4-chloro-3(H)-pyridazin-3-one, is a heterocyclic acaricide It is widely used in the production of cotton, peach, apple, pear, citrus, tea, etc. to prevent ...
