Abstract:

The chloroform extract of Polygonum minus Huds. was found to exhibit inhibitory effect against Fusarium oxysporum f.sp. lycopersici under laboratory conditions. Hence a new botanical fungicide (Polymin 40 EC) was formulated from the chloroform extract of Polygonum minus Huds. Polymin 40 EC to control the pathogen under in vivo conditions. Various concentrations of Polymin 40 EC were evaluated for their performance on seed infection, germination and vigour of tomato and it was found that Polymin 40 EC at 2% concentration increased the germination and vigour with the significant reduction in seed infection. Application of Polymin 40 EC increased the activity of plant defense enzymes such as peroxidase (PO), polyphenol oxidase (PPO), phenylalanine ammonia lyase (PAL) and phenol content of tomato plant. Application of two percent Polymin 40 EC was found to be effective in controlling the incidence of Fusarium oxysporum f.sp. lycopersici in tomato plant.
