The chloroform extract of Polygonum minus Huds. was found to exhibit inhibitory effect against Fusarium oxysporum . 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. | Nội dung Text Controlling the incidence of fusarium oxysporum . lycopersici in tomato by application of the newly formulated botanical fungicide Polymin 40 EC
