Abstract:

Trichoderma harzianum, a biological control agent seems to be suitable for management of plant pathogens. In dual culture, antagonistic activity of T. harzianum was effective against Sclerotium rolfsii showing 66.60 percent inhibition, Fusarium solani with 56.70 percent inhibition and 30.90 percent inhibition against Fusarium oxysporum. The formulation study states that it can be also promoted in liquid formulation which has higher shelf life and stress protection. Paraffin oil, soy bean oil, combination of paraffin oil and glycerol (1:1), paraffin oil and soybean oil (1:1), soya bean oil and glycerol(1:1), were used. Absence of colonies of Trichoderma harzianum was observed in soybean oil and glycerol (1:1) at 42nd day, whereas on 49th day Trichoderma showed nil growth in paraffin oil and glycerol (1:1). On 56th day paraffin oil and soybean oil showed nil growth of Trichoderma. Paraffin oil showed higher activity of Trichoderma harzianum with 20 x107cfu/ml followed by soybean oil with 2.1x106 cfu/ml at 56th day.
