Abstract

Three different application methods of Trichoderma harzianum viz., seed treatment, soil application and combination with fungicides were against wilt disease of tomato caused by Fusarium oxysporum f. sp. lycopersici. Among the different seed treatment methods (bio-priming during and after imbibitions, seed coating, wheat bran based (WBB) and talc based formulations, tested maximum seed germination (78.33%) and disease control (66.53%) were observed in bio-priming during imbibitions. Among the delivery of different formulations (bagasse+T. harzianum 10 and 5%, WBB, talc based, farm yard manure based) of T. harzianum in soil significantly lowered disease incidence (17.67%) and maximum disease control (77.82%) was recorded in WBB formulation which was statistically at par with bagasse+T. harzianum 10% (20.00 and 74.89%). Among combination treatments, a combination of FYM+T. harzianum 50 g/kg (SA)+carbendazim 2 g/kg (ST) proved superior to higher germination (84.33%) and disease control (86.60%)).
