SYED ASIM REHAN KAZMI, SALEEM SRAHZAD* AND ISHRAT NIAZ

Abstract: Effect of neem oil and benomyl on the growth of root infecting fungi viz., Macrophomina phaseolina, Rhizoclonia solani and Fusarium moniliforme was examined. Benomyl showed greater suppression in growth of R. solani and F. moniliforme than neem oil whereas neem oil @ 0.1 % was more effective against M. phaseolina than benomyl. Efficacy of benomyl and neem oil increased with increase in concentration. Neem oil extracted from seed samples collected from different localities showed variable suppression of growth of the test fungi.
