In this study, the effect of pesticides with different modes of action is assessed in the standard test species Enchytraeus albidus. These are important inhabitants of a wide variety of soil types and suitable test organisms for environmental risk assessment through the determination of effects on survival and reproduction. The main goals of this study were to test the toxicity of a range of pe...

For ecological risk assessment, the additive model may be used to empirically predict toxic mixture effects. Detailed toxicity tests were performed to determine whether effects of mixtures of copper-cadmium and copper-carbendazim on Caenorhabditis elegans were similar to the effects of the individual compounds. Effects on the course of reproduction, the length of the juvenile period, the length...

There is considerable and ongoing debate as to the harm inflicted on bees by exposure to agricultural pesticides. In part, the lack of consensus reflects a shortage of information on field-realistic levels of exposure. Here, we quantify concentrations of neonicotinoid insecticides and fungicides in the pollen of oilseed rape, and in pollen of wildflowers growing near arable fields. We then comp...

The occurrence resistance to methyl benzimidazole carbamates (MBC)-fungicides in the Fusarium graminearum species complex (FGSC) is becoming a serious problem in the control of Fusarium head blight in China. The resistance is caused by point mutations in the β2-tubulingene. So far, five resistant genotypes (F167Y, E198Q, E198L, E198K and F200Y) have been reported in the field. To establish a hi...

The chemical management of the black leaf streak disease in banana caused by Mycosphaerella fijiensis (Morelet) requires numerous applications of fungicides per year. However this has led to fungicide resistance in the field. The present study evaluated the activities of six fungicides against the mycelial growth by determination of EC50 values of strains collected from fields with different fu...

A Gram-positive, aerobic, non-motile, mesophilic strain, djl-6(T), able to degrade carbendazim, was isolated from a carbendazim-contaminated soil sample from Jiangsu province, China. The taxonomic position of this isolate was analysed by using a polyphasic approach. Chemotaxonomic analysis including peptidoglycan type, diagnostic sugar composition, fatty acid profile, menaquinones, polar lipids...

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 99% inhibition of radial mycel...
