Ten strains of fungi were tested for tolerance to the fungicide benomyl. Verticillium chlamydosporium strain 2 did not grow in the presence of benomyl; Drechraeria coniospora strains 1 and 2 and Chaetomium sp. tolerated only 0.1 mug benomyl/ml medium; Acremonium bacillisporum, an unidentified fungus, and Phoma chrysanthemicola uniformly grew at 1 mug/ml, but some hyphae grew at higher benomyl c...

Fungicide benomyl is easily decomposed to carbendazim (MBC) and butyl isocyanate (BIC) in formulation, BIC is further hydrolyzed to butylamine. The BIC also reacts with butylamine to form N,N'-dibutylurea (DBU), a phytotoxic compound. The purpose of this study was to investigate the effects of selected additives and the manufacturing method of benomyl water dispersible granules (WG) on reducing...

Pseudomonas fluorescens strain LRB3W1 inhibited the mycelial growth of Fusarium oxysporum f. sp. lycopersici and suppressed the Fusarium wilt of tomato. The chemical fungicide, benomyl, did not suppress the disease incidence at low concentrations. However, the disease incidence was decreased by the combined application of benomyl at low concentrations with strain LRB3W1. Combined application of...

The fungicide benomyl inhibited spore germination and hyphal length of the arbuscular mycorrhizal fungus Glomus mosseae when applied at doses of 21.25 microg/ml (agronomic dose), 10.62 microg/ml and 10 microg/ml. G. mosseae was able to germinate in the presence of 2.12 microg/ml of benomyl, and the percentage of spore germination was unaffected by dosis of 0.1, 0.01 and 0.001 microg/ml of the f...

In this study, the effects of benomyl, a systemic fungicide were investigated in the mitotic cell division in onion (Allium cepa) root tip cells during germination. For this aim, different concentrations (1, 2, 5, 10 and 20 mM) of benomyl solutions were used. All the concentrations used caused several abnormalities in mitotic cell divisions and the mitotic frequency in the onion root tip cells ...

Benomyl is a benzimidazole fungicide that has been widely used on a variety of food crops and ornamental plants. It is known to cause adverse effects on reproductive systems, including decreased testicular and epididymal weights and reduced epididymal sperm counts and fertility. The brain aromatase gene is up-regulated by estrogens and estrogen mimics and considered a target gene to screen estr...

Endocrine disruptor chemicals are known to cause a range of abnormalities in sexual differentiation and reproduction. One mechanism underlying such effects may be via alteration of aromatase activity, which is responsible for estrogen production. A good screening system for identifying endocrine disruptors has long been desired. We have recently established a human ovarian granulosa-like tumor ...

Background: Pesticides are one of the important sources of environmental pollution that influence human health. The aim of current study was to determine diazinon and benomyl residues levels in mushrooms grown in greenhouses. Methods: Mushroom samples were obtained from 10 active greenhouses of Hamadan Province, Iran, every 14 days from May 2014. The absorbance of diazinon and benomyl were me...

The content and homologue composition of alkylresorcinols were investigated in rye seedlings (Secale cereale L.) treated with benzimidazole fungicides and grown for 5 days under various thermal and light conditions. The fresh and dry biomasses of green and etiolated plants were greatly increased by benomyl and carbendazim at 29 °C. At 22 and 15 °C benomyl had an inhibitory action on growth of r...

Registered treatments for the control of avocado anthracnose caused by Colletotrichum goeosporioides are post-harvest applications of prochloraz and thiabendazole. Pre-harvest treatments to reduce inoculum levels in the field are also an important factor for successful anthracnose disease control. Pre-harvest application of benomyl was previously registered for this purpose, although at this st...
