FIELD EVALUATION OF NEW FUNGICIDES AGAINST RICE (ORYZA SATIVA) DISEASES

Abstract

Rice crop is attacked by various pathogens in the field which are responsible for low yield. In order to control the diseases new chemicals were tested in the field against rice blast, bacterial leaf blight of rice and brown leaf spot in rice. All chemicals were found effective for reducing diseases incidence and improved paddy yield as compared to control with varying degree. Susceptible variety Basmati C-622 was planted in puddled field. Heavy dose of NPK @ 150:85:00 (Kg/ha)was applied to encourage disease to increase blast incidence. Gem Star Super 325 SC & TC @ 296.4 mL/ha was the most effective treatment against Paddy Blast while in case of bacterial leaf blight of rice basmati 2000 was test variety. Nativo75 WG @160.55gm/ha was highly effective against bacterial blight whereas Score 250EC@ 308.5mL/ha outclassed all the tested fungicides against brown leaf spot of rice on basmati super variety.
