Fungicidal management of blast disease (Pyricularia grisea) of rice

Author(s):

Abstract:
Field experiment was conducted to find out an effective fungicide to manage the blast disease of rice at AICRIP, RRTTS, Chiplima during kharif season of 2016 and 2017. A number of chemicals were used for both seed treatment and spraying and all of them were found effective to manage the disease as compared to untreated control. Among 11 treatments, seed treatment with tricyclazole 75 WP @ 3g/kg seed followed by 2 spraying of tricyclazole 75 WP @ 0.6 g/l recorded minimum leaf blast severity and neck blast incidence in terms of per cent disease index (PDI) with highest BC ratio of 1.71. It was closely followed by seed treatment with carboxin 37.5% + thiram 37.5% @ 2.5 g/kg seed and 2 foliar spraying of isoprothiolane 40 EC @ 1.5 ml/l. Both the treatments were statistically at par with each other with respect to leaf blast infection, neck blast incidence as well as yield.
