Description :
Wide variety of economically important crops was affected by vascular wilt disease which is caused by Fusariumoxysporum. Wilt disease caused by F. oxysporum was one of the main reasons for reduction in yield of Vignaradiata (mung beans). The use of synthetic fungicides not only degrades environment and health but also lead to the development of fungicide resistant phytopathogens. To overcome these harmful effects, pyocyanin can be used as one of the alternatives. Pyocyanin pigment extracted from Pseudomonas aeruginosa MH038270 was examined for activities that inhibit the growth of phytopathogenic fungus in vitro. The antiphytopathogenic effect of pyocyanin was tested on the germination of F. oxysporum infected mung beans and purified pyocyanin had inhibitory effect on fungus. It was found that the seeds treated with pyocyanin showed better growth than the non-treated seeds.
