Abstract

The invention discloses a desinsection composition containing nitenpyram and imidacloprid. The desinsection composition has higher cooperative synergism and has the characteristics of overcoming and delaying insect drug resistance, preventing spectrum enlargement, high desinsection speed, low drug cost, and the like. The desinsection composition is prepared from nitenpyram, imidacloprid, and proper quantities of pesticide addition agents or carriers, wherein the nitenpyram and the imidacloprid are used as active ingredients, and the weight ratio of the nitenpyram to the imidacloprid is 0.1-40:0.1-40. The desinsection composition can be widely applied to crops such as grain crops, rice, cotton, vegetables, fruit trees, and the like to prevent various injurious insects.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition with nitenpyram and imidacloprid as active ingredients. technical background [0002] The loss of crop yield due to pests and diseases of crops is immeasurable, and chemical control is the main way to control the occurrence of pests and diseases. For this reason, it is necessary to apply a large amount of pesticides for pest control every year to recover the loss of crop yield. In recent years, the harm of insect pests on crops such as rice, fruit trees, vegetables, flowers and various economic crops has become more and more serious, and due to the abuse of pesticides, the resistance of pests to pesticides has become more and more serious, causing pest control. The effect decreases every year. Therefore, there is still a need for pesticide varieties with better pest control effects. [0003] Nitenpyram has the characteristics of high efficiency, low tox...
