Abstract

The invention provides a pymetrozine-containing insecticidal composition. The active ingredients of the insecticidal composition consist of flubendiamide, monosultap and pymetrozine, wherein the weight ratio of the flubendiamide to the monosultap to the pymetrozine is (2-15) to (15-80) to (1-23). The pymetrozine-containing insecticidal composition disclosed by the invention has an obvious synergistic effect and a lasting effect which are higher than the single using effect, according to the formula of the Sunyunpei cotoxicity coefficient, the cotoxicity coefficient of the insecticidal composition in each ratio is 170.89-279.00 and is larger than 120, the composition has obvious synergistic and lasting control effects, the insecticidal spectrum is widened, and the composition has high activity on rice planthopper, tryporyza incertulas, Chilo suppressalis, rice leaf folder, brassicaceous vegetable plutella xylostella, aphid and sugarcane pests. According to the insecticidal composition disclosed by the invention, the application dosage of each active substance is greatly reduced, and due to the increase of the monosultap with the weight which accounts for 15-80 percent of the total weight, the cost of the composition is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to an insecticidal composition containing pymetrozine. Background technique [0002] my country is a large agricultural country, and needs to use only 7% of the world's arable land to grow crop products that feed 21% of the world's population, so crop products must be high-yielding to meet the needs. However, crops are often harmed by diseases, insect pests and weeds, which reduce production and income, and insect pests have a greater impact on crops. Therefore, pesticides and pesticides play an important role in ensuring high yield and high harvest of crops. [0003] In the selection of pesticide varieties, it is necessary to choose pesticide varieties that are friendly to the environment, have high efficiency, low toxicity and low residue. Due to the single use of a certain insecticide, pests are likely to develop resistance, resulting in poor control effects, resulting in a ...
