Linseed is an economically important oilseed crop, which is subjected to infection by a host of several pathogens which are responsible for low productivity. Fusarium oxysporum f. sp. lini causing Fusarium wilt is one of the most important disease in hot and dry conditions and yield losses upto 80%. Trichoderma grows on the rhizosphere and on the surface of the roots, thereby provides disease control and enhances root growth. The present investigation was different formulated of Trichoderma such as T. viride 5% in chalk powder, T. viride 10% in chalk powder, T. viride 15% in chalk powder, T. viride 5% in talc powder, T. viride 10% in talc powder, T. viride 15% in talc powder, T. viride 5% in charcoal powder, T. viride 10% in charcoal powder, T. viride 15% in charcoal powder, T. viride capsule and T. viride tablet used to address the problem of linseed wilt. Out of the eleven different formulation tested, Trichoderma viride charcoal powder base 10% was found superior control 14.36 % and yield upto 115 gm/plot followed by Trichoderma viride 15% in charcoal powder control wilt disease 11.46 % and yield 102 gm/plot to reduce the incidence of linseed wilt and maximum yield loss in chalk powder and also found maximum wilting percent and less control wilt disease on chalk powder, talc powder base formulations.
