Maneb is a broad spectrum fungicide, often reported as a carcinogenic, teratogenic and neurodegenerative agent. Thus, the occurrence of maneb at non-targeted sites is a cause of concern. The present study investigates adsorption– desorption behaviour of maneb in the agricultural soils to know its fate, mobility and availability in the soil. The sorption study was carried out by batch equilibrat...

A highly sensitive fourth derivative spectrophotometric method is presented for the residue analysis of ethylenebis dithiocarbamate fungicide Maneb. The fungicide maneb forms a blue complex with sodium molybdate on heating which is studied spectrophotometrically. The method has been successfully applied to maneb determination in wheat grains and soft drinks with high recoveries. The analytical ...

The fungicide maneb is moderately soluble in water and undergoes hydrolysis. Its main products for hydrolysis and photolysis are EU, ETU, EBIS, and glycine. Microbial degradation of maneb represents a minor breakdown route. Aquatic metabolism yields the main products EBIS, ETU, and EU. A field dissipation study showed that maneb persisted in soil for one week when applied at 100 ppm. Maneb is a...

Maneb (MB) is a manganese-containing ethylene bis-dithiocarbamate fungicide that is implicated as an environmental risk factor for Parkinson's disease, especially in combination with paraquat (PQ). Dithiocarbamates inhibit aldehyde dehydrogenases, but the relationship of this to the combined toxicity of MB + PQ is unclear because PQ is an oxidant and MB activates Nrf2 and increases cellular GSH...

Exposure of workers to ethylenebisdithiocarbamates (EBDCs; maneb or mancozeb) in 29 potato farms was evaluated during the control of potato late blight. Concentrations of EBDCs and ethylenethiourea (ETU), an impurity and degradation product in EBDC formulations, in ambient air were evaluated during pesticide application. Biological monitoring of exposure to EBDCs was carried out by measuring th...

soybean, glycine max, is susceptible to a large number of disease agents such as seedling and root pathogens that cause serious damages to this crop plant. one of these soil-borne pathogens is macrophomina phaseolina, the causal agent of charcoal root rot. in this study, two bacteria, pantoea agglomerans and bacillus sp. bin, and a fungus, trichoderma harzianum t100, as potential biocontrol age...

The neurodegenerative effects of Parkinson's disease (PD) are marked by a selective loss of dopaminergic (DA) neurons. Epidemiological studies suggest that chronic exposure to the pesticide paraquat may increase the risk for PD and DA cell loss. However, combined exposure with additional fungicide(s) including maneb and/or ziram may be required for pathogenesis. To explore potential pathogenic ...
