    Product Description

    Pencycuron is a phenylurea fungicide.1 It is active against the plant pathogenic fungi G. graminis, R. oryzae, and R. solani, but not P. intermedium or P. irregulare, when used at concentrations of 1 and 10 µg/ml. In plant studies, pencycuron (125, 250, and 500 ppm) reduces the incidence of R. solani-induced sheath blight on rice.2

    WARNING This product is not for human or veterinary use.
