Blast disease caused by Pyricularia grisea, is one of the most devastating diseases of rice in most rice producing areas of the world. In Nepal, the disease causes 10%-20% yield reduction in susceptible varieties, but in severe case, it goes up to 80%. Chemicals are commonly applied for controlling rice blast disease, but when chemicals are used indiscriminately, they also pose a serious threat to the environment. An experiment was conducted to check the efficacy against neck blast disease of rice variety “DY-69” (a Chinese variety) with Hexaconazole 5 SC, Tricyclozole 76 WP and Kasugamycin 3% SL as chemical fungicides while with Trichoderma viridae as biological agent during June to November 2014 in experimental plot with four replications at Plant Pathology Division of Nepal Agricultural Research Council, Lalitpur. The treatments were applied two times .. View More»
