For anthracnose, it is suggested to use bromothalonil or difenoconazole propiconazole or prochloraz manganese salt or prochloraz (note that excessive dosage of propiconazole, prochloraz or prochloraz manganese salt will inhibit growth) or dicyanoanthraquinone or pyraclostrobin.

Prevention first, comprehensive prevention and control. Use pesticide ingredients alternately, and don't use the same pesticide ingredients continuously. This is the principle of plant protection.
