Effect of fungicides and bioagents on root rot/wilt complex of pea in Lahaul valley -A cold desert area of Himachal Pradesh in north western Himalayas

Seed treatment with carbendazim (25%) + mancozeb (50%) gave best management of pea root/wilt complex followed by Bavistin (carbendazim), Raxil (tebuconazol) and carbendazim + mancozeb and also resulted in highest green pod yield during 2007 and 2008. Similar trend was observed in number of pods per plant. But during 2009 and 2010, seed treatment with Vitavax Power (carboxin 37.5%+ thiram 37.5%) @ 2.5 g/kg gave maximum disease control (64.3%) and resulted in highest green pod yield (46.5% yield increase). Seed treatment with carbendazim @ 2.5 g/kg resulted in 56.5% and 22.8% disease control and increase in yield during 2009 and 2010, respectively. Trichoderma viride @ 1.0% gave better control than 4.0% as seed treatment.
