Basrah Journal For Date Palm Research,
Volume 10, Issue 2, Pages 9-19
AbstractThe 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% .
