Abstract

The invention discloses a pesticide composition containing dinotefuran and pyrethroid, and relates to the field of pesticides, dinotefuran and pyrethroid are reasonably compounded, a thickening agent is added, polyethylene glycol is used as a hydrophilic chain segment, L-lysine diisocyanate is taken as a connection point, lauryl amine polyoxyethylene ether containing a long hydrophobic chain segment is taken as a chain extender and n-tetradecanol is taken as an end-capping reagent so that a comb-shaped water-based associative thickener with a hydrophobic chain segment on the side chain is synthesized. The problems that an existing pesticide is prone to flocculation in the storage and use process, and the pesticide cannot be kept in a stable suspension state are solved. Hydrophilic groups of the associated thickening agent and water form hydrogen bonds, flowing of water is limited, hydrophobic groups are associated with each other to form micelles, the hydrophobic groups at the tail ends of the micelles can also adsorb surrounding micelles, the micelles are intertwined, the viscosity of the system is increased, molecules are in multipoint association, the thickening effect is remarkably improved, and thus the purpose of keeping the pesticide in a stable suspension state is achieved.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a pesticide composition containing dinotefuran and pyrethroids. Background technique [0002] Dinotefuran is the latest generation of super neonicotinoid insecticides. Its chemical structure is quite different from that of existing neonicotinoid insecticides. Its tetrahydrofuranyl group replaces the previous chloropyridyl and chlorothiazolyl groups. Contains halogen elements, has a wider insecticidal spectrum, has the characteristics of contact killing, stomach poisoning, strong systemic absorption of roots, high quick-acting effect, and long-lasting effect, and has excellent control effect on piercing and sucking mouthparts pests. It is mainly used to control wheat Aphids, leafhoppers, planthoppers, whiteflies and their resistant strains on various crops such as rice, cotton, vegetables, fruit trees, tobacco leaves, etc., and are effective against Coleoptera, Diptera, Lepidoptera and H...
