EVALUATION THE EFFECTIVENESS OF FIVE ESSIENTIAL PLANT OILS IN THE INHIBITION OF GROWTH OF FOUR TYPES OF PATHOGENIC

Abstract

This research was carried out to evaluate the effectively of five essential plant oils ( Black seeds oil , Cardamom oil , Aniseed oil , Aloevera oil and Clove tree oil ) in the inhibition of growth of four types from fungi (Pythium aphanidermatum , Rhizoctonia solani , Fusarium moniliforme and Fusarium poae ) at 250 , 500 , 1000 part per billion In Vitro . Bioassay test results showed the significant differences and the superiority Clove tree oil in inhibiting the growth of four fungi and as it was ( 0.0 % ,100 % , 100 % ) , ( 37.22 % , 88.07 % , 100 % ) , ( 11.11% , 48.33 % , 71.11 % ) and ( 5.55 % , 100 % , 100 % ) respectively .Meanwhile , the rest of essential plant oils showed different activity on growth of pathogenic.
