چکیده مقاله:
The effect of various pesticides (diflubenzuro, malathion, mancozeb and carbendazim), disinfectants (calcium hypochlorite and formaldehyde) and oil cakes (sunflower and soy-bean oil cakes) commonly used as supplements in mushroom cultivation on the growth of the nematophagous fungus, Arthrobotrys oligospora, was studied under in vitro conditions. Carbenazim caused ۹۹% inhibition of radial mycelial growth in Petri dishes at all concen-trations tested (۱۰-۴۰ µg a. i. ml-۱) in comparison to non treated dishes. Mancozeb caused ۴۳% and ۲۳% inhibition at ۲۵۰ and ۵۰۰ µg a. i. ml-۱ respectively and ۹۹% inhibition at concentration of ۱۰۰۰ µg a. i. ml-۱ and above. Diflubenzuro and malathion at ۱۰-۴۰ µg a. i. ml-۱ caused ۳۰-۴۱% and ۲۴-۵۴% inhibition, respectively. Formalin (۰.۵-۲.۰% v/v) inhib-ited growth of A. oligospora completely. However, calcium hypochlorite, sunflower and soybean oil cake at concentrations of up to ۲.۰% w/v caused less than ۳.۵% inhibition.
