in order to evaluate the effect of rimsulfuron, eptc (eradican), oxadiargyl, metribuzin and metribuzin herbicides for controling of lambsquarter (chenopodium album) and prostrate pigweed (amaranthus retroflexus), an experiment was conducted at the mohaghegh ardabili university green house in 2008. a dose-response assay was conducted based on completely randomized design with four replications. ...

The changes in fatty acid composition o f maize leaf lipids caused by EPTC were generally similar to known effects o f this herbicide in other plants: decreasing o f linolenic acid content and increasing o f its precursors, palmitic, stearic, oleic and linoleic acids. However, novel effects were detected in roots where the proportion o f minor fatty acid palmitoleic acid was increased from 2.1 ...

The weight of epicuticular wax on the surface of cabbage (Brassica oleracea var. Capitata ;Market Prize') leaves was reduced by soil treatments of ethofumesate (2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate) and EPTC (S-ethyl dipropylthiocarbamate). Separation of epicuticular wax into major components by gas-liquid chromatography indicated that ethofumesate decreased the dep...

A nematicide (fenamiphos) and a herbicide (EPTC) were injected into a sprinkler irrigation system separately and as tank mixtures and applied in 25.4 kl water/ha for nematode and weed control on snapbean. There were no differences (P = 0.05) between methods of injection of fenamiphos + EPTC on efficacy or crop response. The root-gall indices of cultivars Eagle and GV 50 were lower in fenamiphos...

By comparison of the Proteus mirabilis HI4320 genome with known lipopolysaccharide (LPS) phosphoethanolamine transferases, three putative candidates (PMI3040, PMI3576, and PMI3104) were identified. One of them, eptC (PMI3104) was able to modify the LPS of two defined non-polar core LPS mutants of Klebsiella pneumoniae that we use as surrogate substrates. Mass spectrometry and nuclear magnetic r...

The complex roles of cell surface modification in the biofilm formation of Campylobacter jejuni, a major cause of worldwide foodborne diarrheal disease, are poorly understood. In a screen of mutants from random transposon mutagenesis, an insertional mutation in the eptC gene (cj0256) resulted in a significant decrease in C. jejuni NCTC11168 biofilm formation (<20%) on major food contact surface...

Soybean (Glycine max [L.] Merr. var. Glabrous D62-7812) plants were grown in aerated Hoagland and Arnon mineral nutrient solution containing 0 or 2.6 mum S-ethyl dipropylthiocarbamate (EPTC) in a growth chamber. After 19 days exposure to EPTC, total leaf fresh weight was reduced 18% by 2.6 mum EPTC while total leaf fatty acid content was reduced 63%. Galactolipid content decreased while phospho...

the same. Only a small amount of non-metabolized EPTC remained. With only minor differences in the EPTC metabolism patterns of the anhydride-treated and non-treated corn, it would be difficult to explain the anhydride's action on the basis of EPTC metabolism alterations. From these results, it is clear that the mode of action of the 1,8-naphthalic anhydride is not that of a simple interference ...

BACKGROUND The Agricultural Health Study (AHS) is a prospective cohort study of licensed pesticide applicators from Iowa and North Carolina enrolled between 1993 and 1997. EPTC (S-ethyl-N,N-dipropylthiocarbamate) is a thiocarbamate herbicide used in every region of the United States. The U.S. Environmental Protection Agency reports that EPTC is most likely not a human carcinogen; however, the p...
