| Abstract | ||
| I solation and I dentification of the fungus from the tissue cultures of six cultivars date palm ( Braim , Hillawi , Sayer , Aum Aldehin , Showathy and Quntar ) was carried out , ten species of fungus was isolated wich are Alternaia alternate , Aspergillis niger , Aspergillus clavatus , Fusarium sp , Fusarium solani , Eurotium amstelodami , Gilmaniella humicola , Penicillium sp , Rhizopus sp , and Ulocladium atrum .Study of evalutation activity of six fungicides ; Mancozeb , Score , Carbendazim , Tachigreen , Topas and Switch reselts indicated that all fungicides showed good activity against isolated fungi . The fungicides Score and Carbendazim showed the highest parentage (100 %) , Topas showed inhibition 94.7 %, Switch achieved inhibition 79.8 % ,Mancozeb 79.4 % however the fungicide Tachigreen showed the lowest inhibition parentage 71.4 % . Also results indicated that Penicillium sp and Rhizopus sp caused highest inhibition 92.7 % and 92.4 % respectively while G. humicola caused the lowest inhibition parentage 76.6 % . | ||
