Infecting Tomato Seedlings Cultivated in Jordan Valley using Garlic Extract]]>AlhussaenKhalaf HusseinEmad I. Al-BataynehKhalid M. Al-KhatibMahmoud Al KhateebWesam JacobJacob H. ShatnawiMohamad A. KhashroumAshraf HegazyMohamed I. 2201152Garlic extract is well known for its antibacterial and antifungal activity and is used to treat several plant pathogens. Pythium sp. was isolated from infected tomato seedlings grown in Jordan Valley (Jordan) and the species was identified as Pythium ultimum using morphological and molecular methods. The fungicidal activity of garlic extract with different concentrations in controlling the growth of the isolated Pythium sp. was determined in vitro. The control activity was highly dependent on Garlic extract concentration. For instance, undiluted garlic extract showed the highest control activity with no growth as compared to the biotic control without the extract whereas diluted garlic extracts 10 and 5% reduced the fungal growth to 15.5 and 41%, respectively. The results of this study show that garlic extract could successfully control Pythium ultimum on tomato seedlings and is considered as an environmentally friendly product.]]>Abdelghani, E.Y., K.
