False smut disease caused by Ustilaginoidea virens (Cooke) (Takahashi) is a grain disease of rice that converts whole grain into powder (smut balls) form. Disease infestation leads to sterile spikelets and reduction in 1000 grain weight. Considering the importance of disease the experiment was carried out to assessment of IDM module with Propiconazole and Carbendazim in rice through on field trials (OFT) against false smut disease in Kabirdham district of Chhattisgarh. The experiment was conducted in two consecutive years Kharif season 2014-15 and 2015-16 at different location of farmer’s field by supervision of Indira Gandhi Krishi Vishwavidyalaya, Krishi Vigyan Kendra, Kabirdham (Chhattisgarh) as an on farm trial for control the false smut of rice. The experiment was observed by calculation of No. of infested Panicle/m2, Disease Incidence (%), No of smut bolls/ infected panicle and yield data with cost: benefit ratio. The use of Propiconazole 25 EC @ at heading stage (50% Panicle emergence) stage increased yield by % with reduced the No. of infested Panicle/m2, by compare to farmer practices(Carbendazim and others fungicides used at recommended dose) no yield changes with % panicle infestation. Propoconazole gave good result in all respective parameters with low cost and high benefit compare to farmer practices. | Assessment of IDM modules with some fungicides for rice false smut disease in Chhattisgarh, India
