Problems solved by technology

But dinotefuran, like many chemical insecticides, long-term, continuous, single-use, will produce resistance
Moreover, due to the long-term use of high-content original drug compounding, not only the drug effect is not good, but the cost is high, and it is easy to cause phytotoxicity, and the dosage forms of dinotefuran insecticide products currently used in the pesticide market mainly include wettable powder, Powders and Granules

Abstract

The invention relates to an insecticidal composition containing dinotefuran and emamectin benzoate. According to active ingredients of the insecticidal composition, a weight ratio of the dinotefuran to the emamectin benzoate is (10-25):(3-10), preferably is (7-15):(3-5). According to the known technology in the technical field, the conventional aid and filling agent are added into the insecticidal composition containing the dinotefuran and the emamectin benzoate to prepare wettable powder, water dispersible granules, a suspending agent, an aqueous emulsion or a microemulsion. According to the insecticidal composition, compared with high-content complexed insecticides, the insecticidal composition has the advantages that after the dinotefuran and the emamectin benzoate are compounded within the insecticidal content range, an insecticidal effect is increased obviously without reduction due to the increase of the content of a synergist, and the cost is reduced; and compared with a formula of low-content compounded insecticides, the insecticidal composition containing the dinotefuran and the emamectin benzoate are obvious in insecticidal effect.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to an insecticidal composition containing dinotefuran and emamectin benzoate. Background technique [0002] For a long time, all liquid pesticides and solid pesticides with considerable solubility in organic solvents, whether they are insecticides, acaricides, fungicides or herbicides, are mostly used in the form of powder or emulsifiable concentrate . According to statistics, the production of powders and emulsifiable concentrates in my country accounts for two-thirds of the total output of pesticides. Pesticide powders and pesticide emulsifiable concentrates have always been important formulations of pesticide preparations. However, due to the drift of the pesticide powder and the pesticide emulsifiable concentrate contains a large amount of flammable organic solvents that are harmful to humans, animals and the environment. Make in production, storage and use process, produce p...
