Abstract
This study was carried out to evaluate the antifungal activity of Syzygiumaromaticum and Juglansregia ethanol extracts against Fusariumsolani causing cotton seedling damping-off on PDA and under greenhouse condition.Toxicity the concentration, 0.5, 1, 2.5, 5, 10, 15, 20 mg/mg of S.aromaticum extracts in growth of fungus pathogen, and was tested the concentration5, 10, 15, 20, 30, 40 mg/mg ofJuglansregia . Results showed that S.aromaticum ethanol extract was mor effective than J.regia extract. The inhibition percentage of pathogenic fungal growth was found to be 76.6 , 84.4 with the concentration o.5, 1 mg/mg and found to be 100% with the concentration 5, 10, 15, 20 for the Syzygiumaromaticum ethanol extract while the inhibition percentage was found to be 43.3, 57.7, 70, 73.3, 100, 100% for the Juglansregia ethanol extracts at the concentrations respectively .However; in the green house, the treatment seed withSyzygiumaromaticum and Juglansregia ethanol extracts at 2.5 and 30 respectively was led to significant reduced the percentage of pre and post emeraence damping off compared with control treatment. The percentage of seedling damping off pre and post emerging were reached 12.5, 20.7 respectively withSyzygiumaromaticum ethanol extract , while it reached 20.7, 37.5 respectively withJuglansregia ethanol extracts , compared with 41.7, 50% respectively for the control treatment, which indicate that the active compound in the extracts controling of this pathogen.
