| Abstract/Description: | High incidence (32.6 to 37.5 %) of stem canker during 2009-10 followed by a moderate (6.8 to 7.5 %) and low (2.5 to 2.8 %) level during 2010-11 and 2011-12 respectively were recorded in Kanpur and Fatehpur districts of Uttar Pradesh. Trichoderma harzianum isolates, 1 & 2 and Trichoderma viride isolates, 1, 2 & 3 completely overgrew Rhizoctonia solani mycelial growth by > 65 %. Bacillus subtilis DTBS-5 and DTBS-4 and Pseudomonas fluorescens pf-3 and pf80 inhibited R solani by > 50 % and were significantly superior to other isolates. Selected B subtilis and P fluorescens reduced stem canker by 45.5 to 63.6 % and black scurf by 55.8 to 76.4 % under field conditions. Highest tuber yield (33.1 t/ha) in P fluorescens pf3 treatment on par with B subtilis DTBS-5 (33.0 t/ha) and pencycuron (32.5 t/ha) was recorded. Trichoderma spp was moderate in reducing the disease and increasing the tuber yield |
