Abstract
The study was conducted at College of Agric./Univ. of Baghdad to evaluate the efficiency of some isolated fungi and water extract of some organic manure in controlling Rhizoctonia solani on Tomato , showed that water extract of sewage wastes reduced significantly of R. solai growth. Results of tablature isolation showed presence of eight genus of fungi , Monilai sp., Alternaria sp. , Penicillium sp. , Macrophomina sp. , Trichoderma sp., Cylindrocarpon sp., Geotrichum sp. and Aspergillus sp. Trichoderma sp. showed high antagonistic degree against R. solai. Combination of isolated fungi from sewage waste, cows , sheep, horses and poultry achieved reduction in percentage of pre mergence damping off at rate of 30.13%,25.13%,26.35%, 23.43%,24.30% respectively and post mergence damping off at rate of 32.00%, 25.58%, 27.45%,25.83% and 26.13% respectively, roots disease index were reduced to 43.16%,33.52%, 81.20%, 32.40% and 32.50% respectively in contrast with control treatment which revealed 54.83% pre emergence, 56.95% post emergence and 85.17% disease index.
