Half-lives (t1/2) of two soil incorporated s-triazines (atrazine and prometon) and two thiocarbamate (EPTC and triallate) herbicides were determined in relation to soil moisture content in two California soils. Treated soils were incubated at three moisture levels in aerated glass vials at 25 +/- 1 degree C and were analyzed at 0, 7, 16, 28, 56 and 112 day intervals. Loss of herbicides in all t...

In the last years the chloro-s-triazine active substance terbuthylazine has been increasingly used as an herbicide and may leave residues in the environment which can be of concern. The present study aimed at developing a bioaugmentation tool based on the soil bacterium Arthrobacter aurescens strain TC1 for the remediation of terbuthylazine contaminated soils and at examining its efficacy for b...

the effect of tillage (conventional and zero tillage), crop establishment (raised-bed and flat-bed), and weed management practices (herbicide alone and integrated approach) was studied on productivity, profitability, nutrient uptake and physico-chemical properties of soil in soybean–wheat cropping system, at new delhi during 2010–2012. sixteen treatment combinations consisting of four tillage a...

Residual herbicides regularly used in conjunction with conservation tillage to produce corn ( L.) and soybean [ (L.) Merr] are often detected in surface water at concentrations that exceed their U.S. maximum contaminant levels (MCL) and ecological standards. These risks might be reduced by planting glyphosate-tolerant varieties of these crops and totally or partially replacing the residual herb...

The contamination of soils, groundwater and surface waters by herbicides poses major clean-up problems. At present, the most common approach is containment, involving costly removal of highly contaminated soils to landfill sites. Bioremediation methods for in situ treatment are needed as alternative and/or supplementary approaches for cost-effective and residue-free clean-up. This project focus...

abstract in order to study of chemical and mechanical weed management methods and their integration in potato (solanum tuberosum), a field experiment was done in 2008 at ferdowsi university of mashhad research field. experimental design was completely randomize block design with 6 treatments and 3 replications. treatment included broadcast herbicide application (standard treatment), between row...

It had been known before [2, 8, 9, 10] that the herbicides of the carbamates group strongly affect physiology of microorganisms. The aim of the present work was to gain an insight into the action of the herbicide CIPC (isopropyl-N/3-chlorphenyl carbamate) on the cells of soil yeast Rhodotorula glutinis, as a model of soil microflora. Attention has been paid to the following questions: the effec...

Global occurrences of herbicide resistant weed populations have increased the demand for development of new herbicides targeting novel mechanisms of action. Metagenomic approaches to natural drug discovery offer potential for isolating weed suppressive compounds from microorganisms. In past research, traditional techniques entailed isolating compounds from living organisms, whereas metagenomic ...
