tailieunhanh - Evaluation of different soil amendments and germplasm / varieties against tomato bacterial wilt caused by Ralstonia solanacearum

Bacterial wilt caused by Ralstonia solanacearum (Smith) Yabuuchi is one of the most destructive diseases of tomato (Lycopersicum esculentum), causing accountable losses of about 10-90 per cent. Present investigations on the disease (R. solanacearum) were carried out during 2014-15 to fulfill the objectives defined, at the Department of Plant Pathology, College of Agriculture, VNMKV, Parbhani. A total of 10 organic amendments evaluated (pot culture) as pre- sowing soil applications were found effective against R. solanacearum. However, significantly highest seed germination was recorded with vermicompost ( %), followed by karanj cake ( %), neem seed cake ( %) and compost (); whereas, significantly highest reduction in average incidence (PEM and wilt ) was recorded with vermicompost (), followed by karanj cake (), neem seed cake ( %) and compost (). Under artificial epiphytotic conditions (root zone drenching method), all the 14 tomato entries evaluated exhibited different reactions against R. solanacearum. However, six entries (Tom-21, Tom-4, Tom17, Tom-13, S-22 and PKM-1) were moderately resistant with average wilt incidence in the range of to per cent; four entries (Tom-15, Tom-11, Tom-27 and Tom-7) were moderately susceptible with average wilt incidence in the range of to per cent and four entries (Tom-8, Tom-18, Tom-2 and Pusa Ruby) were susceptible with average wilt incidence in the range of – per cent. | Evaluation of different soil amendments and germplasm / varieties against tomato bacterial wilt caused by Ralstonia solanacearum
