Antifungal activity of different strains of
Fungicides requirements are excellent potency against a variety of plant pathogens and safety, not only for humans, animals, and host plants but also for the ecosystems. Fungicides of microbial origin, which are synthesized biologically, have been demonstrated to be not only specifically effective on the target organisms but also inherently biodegradable 1 . Microbial products are so complex in their chemical structures that one compound may have two or more totally different chemical moieties which can interact with different receptors 2 .
Antagonistic activity was also observed for
The purpose of this study was to examine the antifungal activity of
Materials and Methods
Isolation of cultures
Five strains of
Test organisms and culture media
Test fungi were isolated on potato dextrose agar (PDA) (peeled potato 250 g, dextrose 20 g, agar 15 g, distilled water 1 L) medium from their respective hosts collected from experimental farm of Banaras Hindu University, Varanasi, India. The cultures were further purified by single spore isolation technique and maintained at 25±2 ° C on PDA slants. 7-10 days old culture were used in the experiment. The fungi included in the present study are

Five strains of
The biological control of soil-borne pathogens with antagonistic bacteria, particularly
Pseudomonads represents the major group of non-differentiating microorganisms that produce antibiotics such as phycocyanin, pyrolnitrin and pseudomonic acid, was investigated in
The presented data exhibit the antifungal activity of
