The resistance to cucumber target spot disease varies from place to place. It is recommended to use difenoconazole and propiconazole (or tebuconazole or bromiostrobin or pyraclostrobin or prochloraz manganese salt or trifloxystrobin, etc.) + bacterial pesticide (thiazole zinc or kasugamycin or Zhongshengmycin).
?The above measures can also prevent and control cucumber spot disease, cucumber black spot disease, cucumber anthracnose, and cucumber bacterial diseases.
If it is a greenhouse, it is recommended to control the humidity and use aerosols to control the disease on rainy days.
Focus on prevention and comprehensive prevention and control. Alternate pesticide ingredients and do not use the same pesticide ingredients continuously. This is the principle of plant protection.
