EVALUATION THE EFFICACY OF SOME ANTIOXIDANT AND SECONDARY METABOLISM PRODUCTS OF TRICHODERMA SPP IN GROWTH AND PATHOGENICITY OF HENDERSONULA TOLUROIDEA THE PATHOGEN OF EUCALYPTUS TREES SCATTERED IN DIFFERENT LOCATION IN ANBAR GOVERNORATE

Abstract

The study aimed to isolate the pathogen of eucalyptus trees scattered in various locations of Anbar University and some of the groves of the city of Ramadi and the surrounding areas that were marked by signs of wilting stems and branches that showed soot deposits. The effect of Trichoderma spp fungi isolated 10 days, 15 days, and 20 days from cuddling was tested, as examination results showed non-inhibiting ratios for both collection dates 10 days and 15 days. The percentages were 0% for both previous collection dates. The results of collection dates after 20 days of the higher vaccine gave an effect in Inhibiting the growth of pathogenic mushrooms H. toluroidea  As the percentage of inhibition reached 73%  the result showed to examine the effect of mixing between products of secondary metabolism of the fungus Trichoderma spp isolated after 20 days from brood and some of the antioxidants, which reached the percentage of inhibition of the growth of pathogenic fungi 100% and 70% and 69% when mixing treatments for secondary metabolites Trichoderma spp. Has hydroquinone, vitamin E and ammonium tartrate, respectively..
