FOUZIA YAQUB* AND SALEEM SHAHZAD
Abstract
Sclerotium rolfsii showed significant negative effect on plant growth due to severe root colonization, whereas, presence of the microbial antagonists showed significant positive effect on plant growth by reducing the colonization of roots by S. rolfsii. Highest root colonization by S. rolfsii and significant reduction in plant growth were observed in sunflower and mungbean plants growing in soil artificially infested with sclerotia of S. rolfsii. Use of biocontrol agents in S. rolfsii infested soil showed significant reduction in Root Colonization Index accompanied by increase in plant growth. Bradyrhizobium sp., was found most effective (p
