Management of Root/Collar Rot Disease in Soybean Konde S. A., Raut B.T., Panzade D.S., Ingle S.H. Department Of Plant Pathology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola-444 104 (Ms) Abstract Root/collar rot is a destructive disease of soybean in India. Seed treatment and soil applications with fungicides, bioagents and its combinations were found effective in reducing the root/collar rot disease incidence in the pot and field conditions and increased grain yield. In pot experiment,seed treatment with Thiram +carbendazim (2+1 g kg -sup;1) was effective in reducing root/collar rot disease followed by Thirarn (3 g kg sup;1) and Thiram +T.viride (1.5+ 4 g kg sup;1) showing 50.43,45.38,and 41.29 percent disease reduction and maximum germination were also recorded in the same treatments. Under field experiment, seed treatment with carbendazim + Thiram (1+2 g kg sup;1) was effective in reducing root/collar rot disease followed by Thiram (3 g kg sup;1), carbendazim (1 g kg sup;1) and soil application of Trichoderma viride + T. harzianum (1+1 kg ha sup;1), showing 74. 64, 72.81, 66.65 and 66.00 per cent disease reduction. Highest grain yield i.e. 1808 kg ha sup;1 in soil application of T. viride + T. harzianum (1 + 1 kg ha sup;1), was recorded as compared to 1298 kg ha sup;1 in check. Highest seed weight per plant (8.65 g) and 100 seed weight (14.75 g) were also recorded in the same treatment. Top Keywords Root rot, collar rot, soybean.. Top | | |
