Abstract

The invention discloses an insecticidal composition containing nitenpyram and indoxacarb and a preparation method of the insecticidal composition. The composition is prepared through mixing the nitenpyram, the indoxacarb, a carrier, a wetting agent, a dispersing agent and other addition agents according to a certain proportion. The preparation method comprises the following steps of: A, respectively weighing an indoxacarb active compound, a nitenpyram active compound, the wetting agent, the dispersing agent, the addition agents and the carrier according to a certain proportion; B, respectively milling the indoxacarb active compound, the nitenpyram active compound, the wetting agent, the dispersing agent, the addition agents and the carrier, uniformly mixing all the fine powder of the indoxacarb active compound, the nitenpyram active compound, the wetting agent, the dispersing agent, the addition agents and the carrier, and crushing the mixed fine powder in a high-speed crusher so as to obtain a mixture; and C, taking out the mixture obtained in the step B, crushing the mixture in jet mill so as to obtain an amine preparation containing the nitenpyram and the indoxacarb. The drug effect is improved, the service life of the nitenpyram and the indoxacarb is prolonged, the usage quantity of agricultural chemicals is reduced, the environmental pollution is effectively alleviated, the food safety is improved, and damage to beneficial organisms is reduced.
