Bioefficacy of botanicals against Fusarium solani isolate, causing root rot of papaya under pot condition

Abstract

Fusarium solani has been reported as a major constraint in the successful cultivation of Papaya, as it caused root rot disease which reduced the yield up to 60-95 percent. The present paper depicts the antifungal activity of some plant extracts on the progress of Fusarium solani. The five different botanicals viz; Garlic creeper (Adenocalymma alliaceum), Neem (Azadirachta indica), Garlic (Allium sativum), Tulsi (Ocimum sanctum) and Makoi (Solanum nigrum) at 10% concentration were evaluated against a different isolate of Fusarium solani (Fs-I to Fs-V) under pot condition. The results revealed that all the plant extracts significantly inhibit root rot incidence on papaya in comparison to the control. Across the aqueous plant extract, garlic creeper was seen most cogent against all the isolates of Fusarium solani as it shows maximum inhibition percent (53.00%) and minimum inhibition percent (45.70%) over control followed by Neem, Garlic, and Tulsi. The maximum inhibition percent of (24.20%) and minimum inhibition percent of (16.40%) over control was recorded by Makoi and considered as the least effective botanicals against the pathogen.
