الملخص EN

This study was conducted in Date Palm Research Center - Basrah University with the aim of testing the susceptibility of F.

equiseti to infect the leaves of date palm, Sayer cultivar.

Some anatomical and chemical changes associated with date palm infection with fungi have been studied, as well as some physiological characteristics of the fungi that cause the disease.

The results of this study showed the ability of Fusarium equiseti to cause infection on the date palm leaf Al-Sayer cultivar.

The study showed the susceptibility of F.

equiseti to the secretion of cellulase and phenol oxidase The enzymatic activity space is 5.8 and 6.5 mm, respectively.

The results of histopathology in infected leaves showed the effect of F.

equiseti on the tissues of infected leaves and that the walls of the cells were analyzed as compared to the tissues that did not show symptoms of infection.
