Abstract

The invention provides an acaricide comprising effective components of: acequinocyl, and at least one selected from abamectin, ivermectin, methylamino abamectin benzoate, and milbemectin. A mass ratio of the at least one selected from abamectin, ivermectin, methylamino abamectin benzoate, and milbemectin to acequinocyl is 50:1-1:50. According to the invention, through the formulation of the effective components, a synergetic effect of the acaricide is effectively improved, and a controlling effect of the acaricide against target pest mites is substantially improved. Because the acaricide has an excellent synergetic effect, the potency of the acaricide is improved, field dosage of the acaricide is reduced, pesticide residue and harm to beneficial living things are effectively reduced; and controlling cost and environment pollution are reduced. According to the invention, action mechanisms of the effective components of the acaricide are fully utilized, such that a synergetic effect is achieved by using the two components, and drug resistance of the pest mites can be effectively retarded or overcome.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, in particular to an acaricide and its application. Background technique [0002] Acarids belong to the class Arthropoda. Herbivorous mites mainly include spider mites, panonychia, gall mites, rust mites, etc. They are common pests that harm vegetables, fruit trees, cotton and other crops, often causing devastating disasters. Agriculturally important pest mites are particularly prone to drug resistance due to their short reproductive cycle, large reproductive capacity, low mobility, and high degree of self-fertilization. [0003] At present, the control of pests of the Arthropoda phylum is becoming more and more difficult. This is mainly due to the resistance of pests to the insecticides used and the impact on the environment caused by increased concentrations of insecticides. In order to avoid impact on the environment, it is necessary to reduce the amount of chemical insecticides used. H...
