Efficacy of Fungicides for the Control of Bakanae Disease of Rice

Six fungicides were studied by poison food technique, the fungicides varied considerably in their toxicity to the pathogen. Bavistin, emisan-6 and benomyl were the most inhibitory with ED₅₀ values of O.80, 0.87 and 1.51 ppm, respectively. The five fungicides, namely bavistin, emisan-6, benomyl, indofil M-45 and captan used for seed soaking, significantly reduced the seed-borne inoculum. Although none of them provided complete eradication but significantly reduced the disease incidence in field and significantly increased the yield.
