Sphinx® Star WDG Fungicide Product Overview & Infographic
Sphinx® Star WDG is a preventive and local systemic water dispersible granule fungicide for the control of late and early blight in potatoes and late blight and botrytis rot on tomatoes.
It is a combination fungicide consisting of dimethomorph and chlorothalonil, both with different modes of action. Dimethomorph, a translaminar product with local systemic properties, disrupts fungal cell-wall formation, reduces reinfestation through its antisporulation activity and has also exhibited some curative activity. Chlorothalonil is a non-systemic foliar fungicide with protective action. However, Sphinx® Star WDG is best applied as a prophylactic treatment.
