Specifications: 97%TC, 95%TC, 48% EC, 40% EC

The Chlorpyrifos TC is white crystalline solids, stable at room temperature, sulfur odor, density: 1.398 (43.5 °ś), melting point 42.5~43.5°ś, steam pressure 2.7mPa (25 °ś), 25 °ś when the solubility in water is 1.4mg/l, propylene alcohol is 650g/l, benzene is 7.9kg/kg, Chloroform 6.3kmg/kg, methanol 450g/kg is soluble in most organic solvents and is corrosive to copper and brass.


Chlorpyrifos have the effect of touch, gastric toxicity and fumigation. The residual period on the leaves is not long, but the residual period in the soil is longer, so the control effect of underground pests is better, and there are drug damage to tobacco.

Suitable for rice, wheat, cotton, fruit trees, vegetables, tea trees on a variety of chewing and puncture type mouthpiece pests.
