Abstract

Seed treatment by Pseudomonas aeruginosa RsB29 controlled Fusarium-wilt and charcoal rot disease of chickpea both in vitro and in vivo. Antifungal compounds produced by this strain also inhibited growth of the pathogens, Fusarium oxysporum f. sp. ciceri and Macrophomina phaseolina. The antifungal compound was purified through TLC and HPLC and on spectral analysis indicated the presence of crotonyl group, secondary amine, aryl and α, β unsaturated ketone, diazo, ether and thioether groups.
