Abstract

A laboratory study and field survey of palm trees scattered in Tikrit University, Iraq was conducted during the year 2016 The study included a field survey of palm trees infected with leaf spotting and their control with fungicides trees and pesticide topspin and tasgarin The survey study showed that all colleges of Tikrit University and its accompanying are infected with fungal diseases as they reached the highest percentage The percentage of infected palm trees is 100% in the College of Arts, Veterinary Medicine and Dentistry, the College of Administration and Economics and the Faculty of Physical Education, while the laboratory study demonstrated the efficacy of the pesticide Tobin to inhibit the pathogenic fungi causing the leaves to spot at a concentration of 0.2 ml/liter as the rate of inhibition was zero cm for the fungi F. monilifrome and F. oxysporum compared to the control treatment was 6.1 and 5.3 cm, respectively, while the fungus showed Alternaria sp. High resistance against the pesticide action of the same concentration, as the percentage of inhibition reached 3.35 cm. As for the pesticide, two trees showed high efficiency against fungi causing leaf spotting, as the rate of inhibition was zero for fungi F. monilifrome and F. oxysporum Alternaria sp at concentration 0.3 ml/litre.
