| physicochemical properties |
The original drug is a white granular crystal, stable at room temperature, with a thiol odor, a density of 1.398 (43.5 ° C), a melting point of 41.5 to 43.5 ° C, a vapor pressure of 2.5 mPa (25 ° C), and a solubility of 1.2 mg/L in water. It is soluble in most organic solvents. |
| purpose |
It is a thiophosphate insecticide with contact, stomach poison and fumigation effects. The residual period on leaves is not long, but in soil it is longer, so it has a better control effect on underground pests. At the recommended dose, it is not harmful to most crops, but sensitive to tobacco |
