Abstract

The invention relates to a pyridaben- and clothianidin-containing pesticide composition for preventing and controlling psylla chinensis, namely a composition of wettable powder, a suspending agent and water dispersible granules prepared from the pyridaben, the clothianidin and auxiliaries such as a wetting agent, a disperser, a filler and the like, and a method for preventing and controlling the psylla chinensis by using the pyridaben- and clothianidin-containing composition. The pyridaben and the clothianidin are mixed according to a ratio of 1:2-2:1 and the mixture is particularly effective on adults and nymphs of the psylla chinensis. The pyridaben- and clothianidin-containing pesticide composition can be used for preventing and controlling the psylla chinensis for pears, also can be widely used for preventing and controlling bemisia tabaci gennadius, aphid and nilaparvata lugens for vegetables, cotton and rice, and has high application value and remarkable economic and social benefits.

Description

(1) Field of invention: [0001] The present invention relates to a compound containing 2-tert-butyl-5-(4-tert-butylbenzylthio)-4-chloro-2H-pyridazin-3-ketone (hereinafter referred to as pyridaben (pyridaben)] and E-1- (2-Chloro-1,3-thiazole-5-methylene)-3-methyl-2-nitroguanidine [hereinafter referred to as clothianidin (clothianidin)], wetting agent, dispersant, filler, etc. Suspension concentrates, water dispersible granules and wettable powder compositions made of formulations. [0002] Simultaneously, the present invention relates to a method for controlling pear psyllid by using the composition of pyridaben and clothianidin. The composition can also be widely used for controlling whitefly, aphid and rice planthopper in vegetables, cotton and rice, and has great application value and remarkable economic and social benefits. (2) Technical background: [0003] Pyridaben (pyridaben), also known as fastaben, is a heterocyclic acaricide widely used in the production of citrus...
