Miticide and pesticide composition containing bifenazate and spirotetramat

Abstract

The invention relates to a miticide and pesticide composition which comprises the effective components of bifenazate and spirotetramat. The mass ratio of the two effective components is (1-80):(1-50), the preferable mass ratio thereof is (1-50):(1-25), and the optimal mass ratio thereof is (1-35):(1-20). After relevant auxiliary agents and packing materials are added, the miticide and pesticide composition can be processed into the dosage forms of cream, emulsion in water, suspending agent, wettable powder and water dispersible granules. The miticide and pesticide composition can be used for preventing and treating various mites comprising red spiders, yellow spiders, rust louses, yellow tea mites, tetranychus cinnabarinus, bimaculate tetranychidae, and the like and various sucking insects comprising aphids, thrips, plant louses, mealybugs, white flies, scale insects, and the like for various fruit trees comprising citrus trees, apple trees, grapes, tropical fruit trees, pear trees, and the like, tea trees, various crops comprising cotton, soybean, hop, potato, and the like and vegetables.

Description

Technical field: [0001] The invention relates to a compound of an insecticidal and acaricidal composition containing bifenazate and spirotetramat. technical background: [0002] The English common name of bifenazate is bifenazate, which is a new type of hydrazine ester compound. It is a specific acaricide, which is active during the active stage of spider mites, and can also prevent the egg stage of pests such as Tetranychus urticae. Laboratory studies have shown that it is non-toxic to predatory beneficial mites. Low toxicity to mammals, short residual period. [0003] As a new hydrazine ester professional acaricide, bifenazate has the risk of high cost and gradually increasing resistance. And because of its non-systemic properties, even if the duration of efficacy can reach 30 days, the rainfall after application has a great influence on the efficacy. Reasonable mixing with different types of acaricides, especially acaricides with systemic effect, is conducive to fully...
