Second, the application of tea for export products in our province
Our province is a big tea producing province. Because of the heavier pests on tea trees, the amount of medicine used is larger. In recent years, the problem of pesticide residues has been plaguing the province's tea exports, resulting in a sharp decline in tea prices, seriously affecting the enthusiasm of tea farmers in our province. The use of low-toxic, low-residue pesticides to control tea tree pests and diseases is one of the key measures to solve this problem.
Uranus is a very comprehensive and excellent insecticidal and acaricidal agent for controlling pests on tea. In the EU pesticide residue testing program, its maximum allowable residue limit is 5.00 mg/kg, while cypermethrin allows Limited to 0.02 mg / kg, so Uranus is used at the correct dose without worrying about residual problems.
