Widely used in vegetable downy mildew, blight, seedling damping-off disease, tobacco black shank disease and other disease caused by the flagella bacteria. Without considering the premise of pathogenic fungi resistance, its efficacy is much higher than the current widely used medicine such as metalaxyl, Cymoxanil, fosetyl, oxadixyl. 

If alone used, it has a relatively high risk of resistance, so often associated with other protective fungicide to retard the generation of resistance.
