| Abstract | A study was carry out to detect effect of Rizolex(Tolclofosmethyl ) on growth of some isolates of a pathogenic fungus Rhizoctonia solani Kuhn and growth ,sporulation and spore germination of biocontrol agent Trichoderma harzianum Rifai in vitro .Results showed that Rizolex was strongly growth inhibition of R. solani (100%) at all concentrations (0.025 , 0.05,0.25 and 0.5 ppm) ,while it’s less inhibited to T. harzianum (65.60% - 79.66%) compared with R. solani .Result of sporulation of T. harzianum showed that Rizolex reduce number of formed spores about 40.8% - 49.6 % compared with control . Germ tubes length of spores of T. harzianum decreased 30.6% , 34.88% and 43% by effect of fungicide concentrations 0.05, 0.25 and 0.5 ppm respectively .Also the percentage of spores germination were reduced 42% , 40.5% and 36.6% at same concentrations .While ,there are significantly different in spores germination of T. harzianum between concentrations 0.05 and 0.5 ppm (42% and 36.6%) . |
