Abstract

The invention discloses a pest killing composite containing thiamethoxam and imidacloprid, as well as a preparation method and application thereof. The pest killing composite is characterized by containing the thiamethoxam, the imidacloprid and other adjuvant, wherein the weight ratio of the thiamethoxam to the imidacloprid is 0.1-30:0.1-60. The pest killing composite can be applied to prevent and treat various piercing and sucking type pests. The composite is safe, environment-friendly, low in cost and good in effect. The indoor toxicity test and the test of pesticide effectiveness in fields prove that the compound of the two composites has obvious effect on target pests. In addition, as reports about the blending of the thiamehoxam and the imidacloprid do not exist at home and abroad, the invention is provided.

Description

technical field [0001] The invention belongs to the field of pesticide compounding, and relates to an insecticidal composition and its application, in particular to a fungicidal composition with thiamethoxam and imidacloprid as main active ingredients and its application. Background technique [0002] In the actual process of agricultural production, the application of chemical agents is the most effective means of controlling plant diseases and insect pests, but the most likely problem caused by chemical control of pests is the generation of pest resistance. Moreover, long-term continuous high-dose application of a single chemical insecticide is likely to cause a series of problems such as drug residues and environmental pollution. Reasonable compounding or compounding of chemical insecticides can expand insecticidal spectrum, improve control effect, prolong application period, reduce dosage, reduce phytotoxicity, reduce residue, and delay the occurrence of drug resistance ...
