Abstract

The invention provides a neonicotinoid insecticide, comprising the following components in parts by mass: 15-30 parts of thiamethoxam; 10-20 parts of cyclopyrid; 8-12 parts of diflubenzuron; ecdysone 0.1-2 parts; emulsifier 1-3 parts; disintegrant 0.3-0.9 parts; dispersant 0.8-2 parts; antifreeze agent 0.2-0.8 parts; carrier 60-120 parts. The neonicotinoid insecticide of the present invention contains a variety of active ingredients, which can improve the control effect; has a long duration; contains non-single active ingredients, and is not easy to produce drug resistance; can prevent and control a variety of different types of pests that occur in combination, thereby It can reduce the dosage of medicine, save the cost and reduce the pollution to the environment.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a neonicotinoid insecticide. Background technique [0002] Pesticides are the main method of controlling pests in agriculture. However, due to the irrational use of pesticides, pests can develop resistance to pesticides. For example, diamondback moth has developed resistance to more than 50 insecticides, even benzoylthioureas, insect growth regulators, spinosads, and Bt, which were previously considered difficult to develop resistance, have also developed resistance. . The emergence of pest resistance has increased the difficulty of pest control, and increasing the amount of pesticides used in the field not only increases the burden on farmers, but also is the key source of a series of problems such as human and animal poisoning, pesticide residues, etc., and also makes many hard-won new varieties of pesticides lose efficacy. [0003] Neonicotinoid insecticides are a class of high-e...
