Frogeye leaf spot (FLS), caused by Cercospora sojina Hara, is a vital disease of soybean [Glycine max (L.) Merrill] in most soybean growing countries of the world. Lesions of frogeye leaf spot on leaves begin as small, gray, water-soaked spots and develop into gray to brown spots surrounded by narrow, dark reddish-brown margins. These spots were circular to angular in shape and vary in size. As the lesions age, the central areas become ash gray to light brown. In vitro evaluation of seven fungicides viz., tebuconazole, prochloraz + tebuconazole, azoxystrobin + tebuconazole + prochloraz, pyroclostrobin + mefentrifluconazole, tebuconazole + sulphur, carbendazim + mancozeb and hexaconazole, completely inhibited the growth of Cercospora sojina at 50ppm concentration.
