Solvability in water is very little, can be dissolved in the organic solvents such as benzene, dimethylbenzene, kerosene, toluene, acetone, chloroform, trichloroethanes.Solvability in the time of 25 ℃ (g/kg) is: acetone 400, benzene 500, ethanol 45, toluene 400.
Tetramethrin has quick down effect to sanitary insect pests such as mosquito, flies, but lethal poor performance has anabiosis, and use therefore will be mixed with the medicament of other good disinsection effect.
But its action effect is also very single, after large-scale application, resistance risk is also very high.
Summary of the invention
The object of the present invention is to provide a kind of water dispersible granules that contains tetramethrin and application thereof; said composition active ingredient is beta-cypermethrin and tetramethrin; wherein the weight ratio of beta-cypermethrin and tetramethrin is; beta-cypermethrin: tetramethrin=1:5-1:10; farthest alleviated the problem of current pest resistance to insecticide; thereby reduced the consumption of agricultural chemicals; also alleviated the impact for environment; the trend that meets future society environmental protection, composition of the present invention is received best crop protection effect.
Technical scheme of the present invention is:
A water dispersible granules that contains tetramethrin, active ingredient is beta-cypermethrin and tetramethrin, wherein the weight ratio of beta-cypermethrin and tetramethrin is, beta-cypermethrin: tetramethrin=1:1-1:10.
As preferably, the weight ratio of beta-cypermethrin and tetramethrin is, beta-cypermethrin: tetramethrin=1:2-1:4.
The water dispersible granules that contains tetramethrin of the present invention, it consists of following component by weight percentage:
