Effect of Garlic (Allium sativum) aqueous extract against Fusarium solani

Abstract

This study was carried out in the laboratory of plant pathology, plant protection department, College of Agricultural Studies, Sudan University of Science and Technology in 2017.The objective of this study is to evaluate the effect of Garlic aqueous extracts and Tilt fungicides against Fusarium solani in potato in culture media Potato dextrose agar (PDA) in vitro. The fungi are an important causing significant reduction in yield. In the present study, the pathogenic fungi were isolated from infected plant parts. The causal agents were identified as; Fusarium solani. The identification was confirmed by visual culture characteristics, mainly the growth patterns and pigmentation. Aqueous extract was prepared from the Garlic plant. Studies were conducted three concentrations of aqueous extract of Garlic (100%, 50%, and 25%) addition to the control treated with distilled water. The results indicated that, the effect of the aqueous extracts of the Garlic in all concentrations was of significant effect in inhibiting the growth of the fungus compared to the control (). Effect of inhibition increases with increasing concentrations 2days (86.6, 80 and 66.6%) 4 days (72.2, 61.1and 44.4%) 6 days after inculcation (65.2, 52.2 and 34.9%) respectively. In conclusion, this study showed that the Garlic contain antifungal properties that could investigated in further studies.
