esca of grapevine is a serious and injurious disease in grape-growing all over the world, for which no effective control exists. the presented research ,in two separate experiments ,thirteen fungicides (benomyl, thiophanate-methyl thiram, mancozeb, fosetyl-al, metalaxyl mancozeb, caboxin thiram, ortiva, topas, penconazole , tebuconazole ,propiconazole, sodium arsenate, agri-fos ) were evaluated...

Parkinson disease (PD) is a neurodegenerative disorder particularly characterized by the loss of dopaminergic neurons in the substantia nigra. Pesticide exposure has been associated with PD occurrence, and we previously reported that the fungicide benomyl interferes with several cellular processes potentially relevant to PD pathogenesis. Here we propose that benomyl, via its bioactivated thioca...

Bioassays using pellets of agar, thatch-agar and turfgrass-agar were developed using benzimidazole-sensitive Penicillium expansum, to detect the fungicide methyl 2-benzimidazole carbamate (MBC) which is the major fungitoxic degradation product of benomyl [methyl 1-(butylcarbamoyl)-2-benzimidazole carbamate] in thatch and turfgrass clippings. These bioassays were used to estimate the amount of f...

In view of the essential role of phenolic compounds in the development of pathogen resistance in plants, and given the influence that fungicides exert over phenolic metabolism, the aim of the present study was to determine the effect of the application of different rates of fungicide on the metabolism of phenolic compounds in tobacco plants (Nicotiana tabacum L. cv. Tennessee 86). The fungicide...

Muscadine grapes are high in phytochemicals beneficial to humans, such as resveratrol and ellagic acid. Four studies were conducted to explore the relationship between phytochemical content, berry quality, and disease control following full season or early season applications of fungicides. In each study foliar and fruit diseases were lower in the full season treatment compared to the control, ...

Bell pepper is an economically important crop worldwide; however, production is restricted by a number of fungal diseases that cause significant yield loss. Chemical control is the most common approach adopted by growers to manage a number of these diseases. Monitoring for the development to resistance to fungicides in pathogenic fungal populations is central to devising integrated pest managem...

In West and Central Africa, three foliar diseases—early leaf spot caused by Cercospora arachidicola S. Hori; late leaf spot caused by Cercosporidium personatum Berk. & M.A. Curtis (syn. Phaeoisariopsis personata (Berk. & M.A. Curtis) Arx); and rust caused by Puccinia arachidis Speg.— are major constraints to peanut production. Disease distribution and severity vary from region to region with yi...

ABSTRACT Sixty-four isolates of Colletotrichum gloeosporioides were isolated from infected Limonium spp. cultivated in 12 different locations in Israel. All isolates were identified as belonging to the C. gloeosporioides complex by species-specific primers. Of these isolates, 46 were resistant to benomyl at 10 mug/ml and 18 were sensitive to this concentration of fungicide. Based on arbitrarily...

Methyl 2-benzimidazole carbamate, most commonly known as carbendazim, is a widely used broad-spectrum benzimidazole fungicide and a decomposition product of benomyl. Carbendazim is used to control plant diseases in cereals and fruit, including citrus, bananas, strawberries, pineapples, and pome fruits. Although not permitted for use to treat citrus fruit in the USA and Australia, it is permitte...
