Problems solved by technology

However, the development cost of new active ingredients is high, the development cycle is long, and the speed of pest resistance can never be compared
Other methods, such as crop layout adjustment, rotation of different pesticides, etc., are difficult to achieve obvious effects in actual operation.

Abstract

The invention relates to a desinsection composite which has synergy and contains Pyriproxyfen and Abamectin, belonging to the technical field of pesticide. The compounded active pesticide is prepared by the Pyriproxyfen and the Abamectin which have proportion by weight of 0.1:10-50:0.1. The desinsection composite overcomes the deficiencies of the prior art and shows remarkable synergy. When less dosage of the desinsection composite is applied for treating the pests such as bemisia tabaci, rice fulgorid, rice leaf roller, chilo suppressalis, yellow rice borer, thrips, aphids, trialeurodes vaporariorum, leafhopper and diamond back moth, excellent contact insecticide property, stomach toxicity and ovicidal effect are shown.

Description

technical field [0001] The invention relates to a compound composition with insecticidal activity, in particular to an insecticidal composition containing pyriproxyfen and abamectin with synergistic effect, and belongs to the technical field of pesticides. Background technique [0002] At present, there are various compositions for killing harmful arthropods in the prior art. However, in some actual use processes, the effect is always unsatisfactory. Such as the invention patent (CN 1244343A) "composition for killing harmful arthropods" applied by Sumitomo Chemical Industry Co., Ltd. in China on February 16, 2000, which contains at least one selected from 1-(tetrahydrofuran-3-yl) Methyl-3-methyl-2-nitroguanidine and 3-[(2-chloro-5-thiazolyl)methyl]-5-methyl-4-nitroiminotetrahydro-1,3,5 - Compounds of oxadiazine and pyriproxyfen (also known as pyriproxyfen, chemical name is 4-phenoxyphenyl-(RS)-2-(2-pyridyloxy)propyl ether) as active ingredients.
