Abstract:
Tomato is one of the commercial vegetable crops, being affected with many diseases, among which early blight caused by Alternaria solani has become the constraint resulting in huge yield losses. Continuous usage of chemical methods leads to environment, soil and water pollution. Whereas biological control of diseases is long lasting, inexpensive, eco-friendly and harmless to target organisms. Apart from native and commercial bio-control agents, botanicals viz., Trichoderma viride, Trichoderma harzianum, Pseudomonas fluorescens, neem oil and neem leaf extract were also screened against the pathogen. All treatment shows the antifungal activity against the pathogen. Trichoderma harzianum was most effective in disease severity (24.67%) followed by P. fluorescens (25.33%), Trichoderma viride (31.33%), Datura leaf extract (32.67%), Neem leaf extract (36.67%) compare to treated and untreated control (20.33% and 40.33%) respectively.
