In the course of a survey during growing seasons of 2002-04, various fields and pastures in 23 Iranian provinces were sampled. Some 1200 isolates of Fusarium from root, crown, stem and spike of various plants belonging to the family Poaceae were recovered using Nash-Snyder selective medium and purified on potato dextrose agar (PDA). Based on morphological characters, 35 Fusarium species were id...

Endophytic fungi live inside plants, apparently do not cause any harm to their hosts and may play important roles in defense and growth promotion. Fungal growth is a routine practice at microbiological laboratories, and the Potato Dextrose Agar (PDA) is the most frequently used medium because it is a rich source of starch. However, the production of potatoes in some regions of the world can be ...

in order to study the role of pythium species associated with cantaloupe root and crown rot, samples were collected from infected fields in different areas of khorasan razavi province during 2009-2010. the root pieces were washed and cultured on cma-parp medium. the pythium isolates were then purified by hyphal tip method and identified based on van der plaats-niterink mycological key. the path...

Some 350 Trichoderma isolates were obtained from soil samples collected from different parts of Iran. Cultures were purified on 2% water agar by hyphal tip method prior to identification. Obtained isolates were identified using morphological features including colony characters (pigmentation and growth rate on PDA) and microscopic characters such as shape of conidiophores, shape and size of con...

INTRODUCTION Agricultural producers are exposed to a number of different health risks associated with their work environment. AIM The objective of the study was to assess the degree of colonization by fungi in terms of quantity and in terms of variety of species the samples taken from the settled dust from combine threshing of rye cultivation from organic and conventional farms in the Provinc...

chamaecyparis lawsonia, which brings beauty in parks and green space, is attacked by a variety of pathogenic agents specially fungi. in this study, some chamaecyparis lawsonia available in parks that had disease symptoms were  sampled. after sample collection, in order to isolate fungal pathogens, cuts of the infected plant tissues were placed on pda (potato dextrose agar) and later were put on...

safflower (carthamus tinctorius l.) of the family asteraceae is an annual broadleaf oilseed crop with 35-40 % oil. it was originated from southern asia and is known to have been cultivated in china, india, iran and egypt. in iran the safflower cultivation area has increased over 10000 ha in 2008. some pathogenic fungi such as pythium ultimum, phytophthora drechsleri, puccinia carthami, and fusa...
