Blast (Magnaporthe grisea (Hebert) Barr.) is a serious constraint in rice cultivation especially in the mid hills of Himachal Pradesh where ‘neck blast’ phase causes huge yield losses. A field trial was conducted during 2009 and 2010 for the evaluation of fungicides against this serious menace. Two sprays of fungicides namely, metominostrobin 20 SC, tricyclazole (Beam 75 WP), isoprothiolane (Fuji-One 40 EC), propiconazole (Bumper 25 EC) and carbendazim (Bavistin 50 WP) were applied at booting and at 5 to 10% panicle emergence stage. Though all the fungicides significantly reduced the neck blast incidence, tricyclazole and isoprothiolane proved highly effective resulting in 87.9 and 83.8% reduction in neck blast and 33.8 and 29.9% increase in grain yield over check, respectively. Metominostrobin, propiconazole and carbendazim were also found quite effective.
