Synthesis method
O-chloroaniline is prepared by reduction of o-nitrochlorobenzene. For the preparation method of cyanuric chloride, see s-triazine herbicides. In the presence of an acid-binding agent, o-chloroaniline reacts with cyanuric chloride at 85°C to prepare diprofen.
Purpose
1. Mainly used to prevent and control rice blast, anthracnose, downy mildew, scab of melons, and gray mold of various crops.
2.Broad-spectrum, systemic fungicide. It is mainly used for foliar spray and has special effects on Alternaria, Cercospora, Botrytis, Botrytis and other fungi. It can prevent and control rice blast, flax leaf spot, melon anthracnose, downy mildew, scab, tobacco brown spot, tomato leaf spot and gray mold of various crops. The usage concentration is generally 400-500 times liquid spray of 50% wettable powder, and the recommended dosage is 16.8-33.6g active ingredient/100m2.
