Thirteen fungicides were tested in vitro against Phytophthora drechsleri f. sp. cajani by poisoned food technique. Zineb, copper oxychloride, metalaxyl, thiram and captan inhibited mycelial growth completely even at 250 ppm concentration. Man-cozeb checked the growth completely at 1000 ppm Seven selected fungicides were tested in disease sick plot. Metalaxyl when sprayed at 30th and 45th day after sowing resulted in maximurn reduction in stem blight incidence.
