| Abstract | ||
| The results of this study showed the ability of fungus Fusarium equiseti to cause infection on the date palm leaves inoculated with the fungus, and to the ability to infect all cultivars of date palm . showed that the Halawii and Sayer cultivars were the most sensitive to the articial infection compared to other cultivars, Sayer cultivar the highest rate of the development of infection reached to 42.66 mm, followed by Halawii cultivar at a rate of 40.66 mm and a lower rate of infection was noticed in Berhi cultivar as infection rate was 30.66 mm. The also study revealed that F.equiseti has an ability to produce cellulase and phenol oxidase,the enzymatic space reached to 5.6 and 6.3 mm respectively . Also it was showed that the bio agent Trichoderma harzianum was the most active in inhibition of the growth of pathogenic F.equiseti on PDA, the inhibition percentage reached to 68.11%. | ||
