in 2007, an experiment was conducted at the farm of the college of agriculture, isfahan university of technology, in najaf abad (lavark), to study the effects of two pre-emergence herbicides (trifluralin and ethalfluralin) when combined with the three post-emergence herbicides setoxydim, cycloxydim and haloxyfop and the two post-emergence herbicides desmedipham and phenmedipham on weeds and the...

to evaluate the sensitivity of different crops included some pulses to simulated metribuzin soil residues, an experiment was conducted in completely randomized design with factorial arrangement and four replications in research greenhouse of college of agriculture, ferdowsi university of mashhad. treatments included of 8 crops (chickpea, common bean, lentil, corn, wheat, barley, rape seed and s...

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. ...

damping off caused by rhizoctonia solani (isolate ag4) constrains growing soybean in the north iranian province of golestan. the pathogen was grown on malt agar containing 0, 50, 100 or 200 ppm trifluralin then its vegetative growth and virulence were evaluated. the response of soybean cv. williams seedlings grown in soil containing 0, 0.5, 1 and 2 ?g ai g-1 trifluralin was investigated. on mal...

EVALUATION OF AGROCHEMICALS IN SOIL CONVENTIONAL AND AGROECOLOGICAL AGRICULTURAL PRODUCTION SYSTEMS. At the Contestado Settlement, Lapa, PR, soil samples from agroecological and conventional environments were evaluated against agrochemicals alachlor, atrazine, chlorpyrifos trifluralin. For sampling, 3 depths considered, 10 points selected, 5 in an environment, with sampling frequency was at 2-m...

Herbicide degradation is one of the key processes determining whether use herbicide will have any impact on environmental quality, and it dependent various biotic abiotic factors. The present study evaluates factors such as soil type, application rate, incubation temperature, pH, microorganisms sunlight persistence metribuzin its effect enzymes. Half-lives (DT50) varied significantly with rate ...

Metribuzin is a pre- and post-emergence triazinone herbicide used in variety of crops. This degraded the environment into three major metabolites that have high water solubility, to very soil mobility, low moderate persistence soil. paper describes development an analytical method based on ultrasound-assisted extraction GC-MS/MS determination for metribuzin its main plants. The developed provid...

Background Trifluralin is a herbicide and used in agriculture widely. It enters plants through developing roots and stops plant cells from division and elongation (meristemic inhibitor). Extensive application of trifluralin to control annual grasses and broadleaf weeds in agriculture, horticulture and horn garden, leads to environmental pollution and its entrance into the food chain could have ...
