Abstract
The invention discloses a compounded insecticidal composition containing trifluorobenzene pyrimidine. The compounded insecticidal composition contains an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from trifluorobenzene pyrimidine, the active ingredient B is any compound selected from thiamethoxam, imidacloprid, nitenpyram, buprofezin, thiacloprid, clothianidin, acetamiprid and dinotefuran, and the weight ratio of the active ingredient A to the active ingredient B is (1: 80) to (80: 1). The composition disclosed by the invention has a synergistic effect on a variety of pests which endanger agricultural production, so that the dosage of a pesticide is reduced, the residual quantity of the pesticide on crops is reduced, the environmental pollution is alleviated, the composition is safe to human and livestock, the environmental compatibility is good, and the drug resistance for the pests is difficult to generate.
Description
technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a compound insecticidal composition containing trifluoropyrimidine on crop pests. Background technique [0002] Trifluoropyrimidine is a new type of pyrimidine insecticide, which has good control effect on rice planthopper. [0003] However, in the actual process of agricultural production, the most likely problem in pest control is the generation of pest resistance. The compounding of ingredients from different varieties is a very common way to control resistant pests. Different ingredients are compounded, and according to the actual application effect, it is judged whether a certain compound is synergistic, additive or antagonistic. In most cases, the compounding effect of pesticides is an additive effect, and there are very few compoundings that really have a synergistic effect, especially those with a very obvious synergistic effect and a high co-toxicit...
