Pears, persimmons, peaches, plums, apples, roses and other crops are sensitive to chlorothalonil, which may cause phytotoxicity or rust spots on fruits when used. Therefore, it cannot be used on these crops.

Since chlorothalonil has no systemic properties, it mainly forms a protective layer on the surfaces of leaves, fruits, stems, etc. Therefore, the concentration should not be increased arbitrarily during use, otherwise, phytotoxicity will easily occur.
