A rapid method for determining residues of the herbicide metribuzin in soil by laboratory experiment under controlled conditions is described. Field soil fortified with herbicide at concentration of 5 mg kg-1 soil, and maintained at field capacity moisture regime and kept at ambient temperature 25 ± 5°C. The soil samples were extracted with different ratio of methanol/water solution and the res...

Research has documented the effects of tankmixing glyphosate with numerous insecticides on cotton growth and yield; however, no information is available concerning the addition of a residual herbicide such as an aqueous capsule suspension (ACS) formulation of pendimethalin to glyphosate plus an insecticide. Mixtures such as this are important as producers continue to search for costs savings in...

The herbicide, pendimethalin, is used worldwide, but its acute toxicity is not yet widely known. There have been some reported acute pendimethalin poisoning cases in humans and most of them intentionally ingested the concentrated formulation. We describe a 73-year-old man who developed corrosive gastroduodenal injury after accidental ingestion of the diluted (300 times with water) pendimethalin...

Objective: Vanillin (Va), a phenolic substance is a natural antioxidant with proven free radical scavenging activity and offers protection against oxidative damage. This study was designed to investigate the ameliorative effect of Va against metribuzin (Mtz) pesticide-induced toxicity and oxidative stress in rats. Methods: Thirty-two rats were equally divided into four groups: control, vanillin...

to determine the optimum weed management method and plant population density on chickpea yield, a split plot experiment based on rcbd with four replications was carried out at the university of tehran research farm (located in karaj) during 2010-2011. the main factor consisted of nine treatments including: 1. trifluralin pre-plant, 2. pendimethalin pre-plant, 3. complete weeding, 4. imazethapyr...

OBJECTIVES The aim of the study was to investigate effects of the triazine herbicide metribuzin on signal crayfish Pacifastacus leniusculus Dana by determining oxidative stress (thiobarbituric acid reactive substances) and antioxidant indices (total superoxide dismutase, catalase, glutathione reductase) in hepatopancreas, muscle, and gill as well as assessing their histopathology. DESIGN Cray...

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 aim of this study was to assess the impact of metribuzin in surface waters on fish under experimental conditions. The effects of subchronic exposure to metribuzin on fish growth and the development of histopathological changes in selected organs (gill, kidney, liver) and on activity of some biochemical markers (CYP450, EROD) in Danio rerio were investigated during a 28-day toxicity test. Ju...

Metribuzin is an herbicide widely used for weed control that has been identified as a groundwater pollutant. It contaminates the environment even when it is used according to the manufacturer's instructions. To reduce herbicide leaching and increase weed control, new controlled release formulations were developed by entrapping metribuzin within a sepiolite-gel-based matrix using two clay/herbic...

Finger millet (Elusine coracana) accounts for 8% of the total area and 11% production worldwide. It is grown on over 4 million ha globally, mainly food purposes. Millions people in dry lands Central East Africa, South India depend finger as an important source to them (CGIAR, 2001). one most neglected underutilized crops. Additionally, crop has received limited research attention compared wheat...
