Study and identification of pathogenic fungi on the bulb in some species of Allium spp. In Kermanshah province

Amaryllidaceae family is one of the most important monocotyledon that is used for edible and medicinal plants and animals and humans. Amaryllidaceae s can be exposed to plant pathogenic factors, including fungi, due to the presence of underground parts of rhizome, thymus and gland. The most important species of this genus are Alliumwhich has a variety of onion species, garlic and wild gooseberries, which are scattered in rangelands. In this study, the subsurface (Bulb) of some wild onion (Allium spp.) that Suspicious bulb on fungal infusion were selected and firstly, in potato-dextrose agar (PDA) culture medium, to determine the growth rate, growth pattern and color determination of the colony mushroom and then from aqueous agar medium (WA) for purification of fungi (single sporulation and single strain). Valid identification key was used to identify the species. The results showed that two species of Fusarium (Fusarium solani (Mart.) Sacc., Fusarium oxysporum Schlecht.) Caused these contaminations. So, Fusarium, in addition to root and crown rot, is responsible for the production of mycotoxins, causing a variety of harmful diseases for animals, and ultimately contributing to the human diet
