Experiments were conducted during the summer of 2002 at the Rice Research and Extension Center, Stuttgart, AR, to evaluate: 1) various timings of sequential applications of imazethapyr at 0.063 lb/acre (4 oz Newpath/acre) in conventional and staleseedbed rice planting systems utilizing Clearfield ‘CL-161’ and 2) the timing of clomazone application at various rates and timings in conventional ri...

Runoff from farm fields is a common source of herbicide residues in surface waters. Incorporation by irrigation has the potential to reduce herbicide runoff risks. To assess impacts, rainfall was simulated on plots located in a peanut (Arachis hypogaea L.) field in Georgia's Atlantic Coastal Plain region after pre-emergence application of metolachlor (2-chloro-N-(2-ethyl-6-methylphenyl)-N-[(1S)...

efficacy of many herbicides to control broad- and narrow-leaf weeds (grass weeds) in tobacco fields of mazandaran and guilan provinces was investigated. the experiment was randomized complete blocks design in four replications and the following treatments: eptam (eradicane 82% ec) at 6 l.ha-1 which incorporated pre-planting (ppi), trifluralin (treflan 48% ec) at 2 l/ha ppi, cycloate (roneet 72....

Uncontrolled weeds cause considerable losses in the grain yield of pigeonpea. Field experiments were conducted for seven years from 1998 to 2004 on a loamy sand soil to study the effect of weed management on weeds, growth and grain yield of pigeonpea. In some years, weed dry matter was higher than in others, due to variation in rainfall received. Two hand weedings, pendimethalin in integration ...

Herbicides play an important role in the production of crops, but their residues may cause numerous human/environmental problems. Dissipation kinetics of pendimethalin and residues in soil, maize straw and cobs in winter maize under field conditions were studied by gas chromatograph-electron capture detector (GC-ECD). Dissipation followed the first order kinetics and accounted by a biphasic pat...

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...

A field experiment was conducted to study the integrated weed management in groundnut (Arachis hypogaea L.) for consecutive three kharif seasons in 2010, 2011 and 2012 at Breeder Seed Production Farm of Orissa University of Agriculture and Technology, Bhubaneswar with 7 weed management treatments in four replications. Weed free check (two hand weeding at 20 and 40 DAS and manually uprooting of ...

The addition of organic manure affects the biological, chemical and physical properties of soil that control the fate of herbicides. Three dinitroaniline herbicides were studied to asses their persistence, dissipation and residue management in sandy loam soil with and without addition of farmyard manure (FYM) under middle western Indian agro-climatic conditions. The herbicides, pendimethalin [N...

this experiment was carried out at the research farm of faculty of agriculture, university of zanjan in spring of 2012 to introduce an integrated weed management method in fennel. treatments were type of herbicide (trifluralin and pendimethalin), application dose (recommend dose in other crop (r), 75 percent r, 50 percent r, and 0 percent r) and supplemental control (none, one hand-weeding at 5...
