| Abstract | ||
| The fungus Alternaria alternata was isolated from date palm ( Hillawi ,Sayer , Dairy , Khidrhrawi and Gannami cultivars ) at Al-Dair region in Basrah . The pathogenicity test showed that this fungus has the ability to infect the varieties and gave symptoms of inflorescence rot which represented by strand blacking and smuting . The temperature degree 25 Co was found to be an optimal degree for the fungus growth . The fungicides Vacomil and Mezab inhibited the fungus in a percent of 100 % for each one compared to Benlate , Elsa and Topas which led to inhibit the growth in percents of 71.42 and 41 % respectively . the antagonism between Trichoderma harzianum and A. alternata revealed that the antagonism degree between them was 73.3% . | ||
