Status and incidence of False Smut Disease in rice and their chemical management

Author(s): Sumit Kumar Pandey, Prahlad Masurkar and RK Singh
Abstract: Rice (Oryzae sativa) is the most staple food crop in world. False smut of rice (Ustilaginoidea virens) is one of the major emerging and destructive disease especially in high yielding rice varieties. The incidence of flowering of infected tillers was found ranging from 5 % to more than 50 % in different varieties like Sarjoo 52, NDR 359, HUR- 12. The experimental result revealed that the chemicals Amistar Top (azoxystrobin 18.2 %+ difenoconazole 11.4 % w/w SC) Folicur was found most effective where percentage of infective spikelet’s per m2 reduced to 10.75%. In the term of percentage of infected spikelets/panicle, the treatment with Amistar Top (azoxystrobin 18.2 %+ difenoconazole 11.4 % w/w SC) recorded the lowest percentage i.e. 6.35 % which was at par with the treatment Folicur (tebuconazole 250 EC). The grain yield obtained from each plot it was found that the treatment with Amistar Top (azoxystrobin 18.2 %+ difenoconazole 11.4 % w/w SC) gave the highest grain yield/plot (49.64 q/ha) which was at par with the Folicur (tebuconazole 250 EC) i.e. 48.92 q/ha
