The original drug is light yellow transparent liquid, boiling point (107Pa) 112~114 ℃; Relative density (20 ℃)1. 054; Vapor pressure (20 deg C) 0.12; Flash point without cross resistance. Field application has a good control effect on late blight and downy mildew, and the dosage is 2~38 times lower than other fungicides, if the concentration of 50~100 mg/L treatment of potato late blight has a prominent control effect, and the medication period is flexible, long duration. Treatment of grape, cucumber and melon with the same concentration of the agent also had excellent control effect.
O-ethylphosphoryl dichloride was prepared by the reaction of phosphorus oxychloride with ethanol, and then reacted with 1-methylpropanethiol in the presence of an acid binding agent to obtain sulfur-line phosphorus.
broad-spectrum, contact type nematicide, no fumigation effect. The activity of root knot nematode and perforated nematode was higher, and the activity of cyst nematode was poor. Also has insecticidal effect, can control a variety of crops armyworm larvae, tobacco leaf moth, potato tuber moth.
