Abstract

Tomato crop is affected by many fungal diseases of which early blight caused by Alternaria solani (Ell. & Mart.)Sor. is an important destructive foliar disease. In the present study, aqueous extract of ten plants were screened for in vitro antifungal activity against A. solani by poisoned food technique (PFT), dry mycelial weight (DMW) and spore germination method (SGM). For PFT and DMW, five different concentrations viz., 10%, 20%, 30%, 40% and 50% were tested, while spore germination method 50% concentration only was tested. Prosopis juliflora and Punica granatum showed significant antifungal activity in all the methods. Mycelial growth inhibition increased significantly with increase in the concentration of the extract in PFT and DMW. Highest spore germination inhibition was observed in P. juliflora (92%), followed by P. granatum (85%). Present study indicates the potential of these two plants for further work on development and standardization of eco-friendly herbal formulation for the disease management.
