Abstract

The study was conducted in the laboratories of Biology Department college of Sciences which deal with Effects the alcoholic extract of Zingiber and Bliates and Subtilin in control certain fungi that infect -orange fruits in laboratory. The results of this study proved the efficiency of alcoholic extract of ginger plant to provide protection for the fruits of orange from infection with Penicillium, Fusarium, A. flavus were more than biocidal Subtilin and the pesticide chemical Bliates where the percentage of inhibition when it is used the concentration 60% for Penicillium, Fusarium, A. flavus it (100, 100, 83.33) %, respectively, while the percentage of inhibition when using the biocidal in the concentration 2 g / L it( 94.44, 88.88, 77.77) %, respectively, and for the chemical was its impact less on the fungus compared with& extract alcohol and biocidal a percentage inhibition of the fungi at the concentration 0.6 ml / L (83.33, 77.77, 66.66) %, respectively, as shown results of this study differences in the sensitivity of fungi to the alcoholic extract of ginger, bio-chemical where the fungus Penicillium is the most fungi affected with extract and pesticides, where the percentage of inhibition it (100, 94.44 , 83.33)%, respectively, while the fungus A. flavus is the most resistant to extract and bio-chemical where the proportion of inhibition it (83.33, 77.77, 66.66) %, respectively
