ABSTRACT
In vitro studies were carried out to determine the antifungal activity of five plant extracts viz., Allium sativum, Cymogopogon proxims, Carum carvi, Azadirchia indica and Eugenia caryophyllus extracted with either Cold Distilled Water (CDW), Boiling Distilled Water (BDW) or Cold Ethanol (CET) as well two culture filtrates of Trichoderma antagonistic fungi against Fusarium oxysporum f. sp. lycopersici, Botrytis cinerea and Rhizoctonia solani. The results revealed that plant extracts especially those extracted with CDW had strong antifungal activity with significant inhibition on the growth of the three tested fungi. In addition, the inhibitory magnitude of the tested plant extracts to the tested pathogen fungi was proportional to the applied concentrations. The most effective plant extracts were Allium sativum, Carum carvi and Eugenia caryophyllus. Also, the study showed that the culture filtrates of the antagonistic fungus, T. harzianum was more efficiency than T. viride to decrease the growth of tested fungi, but with levels less than plants extracted CDW or benomyl. Findings in this study confirmed that plant extracts can be used as natural fungicides to control pathogen fungi to reduce the dependence on the synthetic fungicides.

The article is quite scholarstic and shows the creativity of the author. More grease to his elbow
