Abstract
The Pepper (Capsicum annuum) is one of the important field crops in the worlds, which its cultivation has been developed, because of its food value and consumptions. But, there are certain diseases, which limited the growth and productivity, out of which the fungal diseases are of high severity. Thus, for this very purpose, a survey was conducted in the pepper growing areas including field and glass houses for fungal diseases identification in Isfahan provinces. The infected pepper plants were collected in the plastic bages and transferred, into the lab. The macro and microscopic studies indicated that there are severed fungal diseases infecting the pepper plant on the areal parts, including Powdery mildews, Downy mildews, Sclerotinia stem rot, early blight and Botrytis molds. Except the Downy and Powdery mildews being obligate parasite, which cannot be cultured the rest were culture from the margin in the infected parts, where the disease were under development on PDA for purification and identifications through tip culture. The results revealed that, there are several fungal species involving including Peronosporatabacina for Downy mildew, Levielullatauricafor Powdery mildew, Early blight, Alternariaalteanataand A. solani, fruit rot, Botrytis cinerea and stem rot due to Sclerotiniasclerotiorum from areal parts.
