Chlorothalonil has a preventive effect on many plant diseases. Chlorothalonil has good adhesion on plant surfaces and is not easily washed off by rain, so it has a relatively long efficacy period, generally 10 days. However, it has no systemic conductive effect and will not be absorbed from the sprayed parts and root system, so spraying should be uniform and thorough. Usually, spraying with 600-1000 times dilution of 75% chlorothalonil wettable powder can effectively control rose black spot, poplar black spot, chrysanthemum brown spot, peony brown spot, rubber tree anthracnose, clivia anthracnose, cherry brown spot shot hole disease and so on. Chlorothalonil has a certain irritating effect on human skin and eyes, and corresponding protective measures should be taken during use.

Spraying with 1000-2000 times dilution of 50% Xiaojunling wettable powder can effectively control rose black spot, rose powdery mildew, rose branch blight, rose gray mold, rose crown gall, tulip blight, lily leaf blight, chrysanthemum mosaic disease, salvia mosaic disease, lawn brown patch, lawn stem rot as well as various root rots, stem rots and so on.
