فعالية المستخلص الكحولي لقشور ثمار الرمان في مكافحة الفطر Rhizoctonia solani المسبب لموت بادرات القطن

Abstract EN

This study was carried out to evaluate the antifungal activity of ethanol extract for Pomegranate peel ethanol extract against Rhizoctonia solani that caused cotton seedling damping-off on PDA and under greenhouse condition.The toxic concentration, 0,5,10,15,20 mg/ml of Pomegranate peel extract were tested in growth fungus pathogen.

The inhibition percentage of fungal growth was found to be 0,42,54, 72,75% respectively.

However، in the greenhouse found that soil treatment with Biocont was more significant reduction in the percentage of seedling damping off pre and post emergences compared with the other treatments.

The percentage of damping off pre and post emergences were reached 29.2,16.6% respectively with Biocont treatment, while were reached 38.3, 33.3% respectively with Pomegranate peel ethanol extract, compared with control treatment with the presence of pathogen fungus where the percentage of seedling damping off pre and post emergence were reached 62.5, 45.8% respectively.

Biocont and Pomegranate peel treatments showed increase in plant height and dry weight compared with the treatment of the pathogenic fungi only
