in order to investigate the efficacy of split, reduced and whole rates of oxyfluorfen in controlling redroot pigweed (amarnthus retroflexus) and also to evaluate possible soybean (glycine max) injuries a experiment was conducted in research greenhouses of karaj collage of agriculture, university of tehran in 2005. treatments included oxyfluorfen doses at 0.25, 0.5, 0.75 and 1 l/ha in one stage ...

Studies were conducted in the period 2009-2011 in the experimental field of the Institute of Land Reclamation and Agricultural Mechanization – Sofia. The following treatments were used: a1 no herbicides with weeds (C0); a2 herbicide oxyfluorfen (Goal 2 E) at a rate of 250 ml / da; a3 herbicide oxyfluorfen (Goal 2 E) at a rate of 500 ml / da. The experiment was set up using long plots, three ver...

The present study evaluated the effects of different dosages herbicides Oxyfluorfen and Trifluralin on crop properties of garlic, including plant height, number of cloves per bulbs as well as economical and biological yield of garlic. In this research, a randomized complete block design, with seven treatments and three replications, along with a control sample (weeding and no weed control), was...

to study the effects of integration of mechanical control with herbicides on yield and yield components of soybean (glycine max) a field experiment was conducted during 2003-2004 at the research farm of agronomy department, agriculture campus of tehran university, karaj. a randomized complete block design (rcbd) of 18 treatments was applied, each treatment being replicated 3 times. treatments i...

Broad spectrum weed control is essential for successful lesquerella [Lesquerella fendleri (Gray) Wats., Brassicaceae] production. Weeds must be controlled during establishment and throughout the growing season. Lesquerella seedlings grow slowly following germination and emergence, and cannot compete well with most broadleaf and grass weeds. Weed competition is particularly critical prior to clo...

Four efficacy and selectivity small plot field trials were carried out in four sunflower hybrids at two localities in Middle Bohemia during 2008 and 2009 with herbicides containing the active ingredients flumioxazin and fluorochloridone. For Chenopodium album, an efficacy of 97% was found after pre-emergent application of fluorochloridone + acetochlor; the efficacy of oxyfluorfen was 88–95%; th...

A Field experiments were conducted for two years at Agricultural Research Station, Bhavanisagar of Tamil Nadu Agricultural University, Coimbatore, India during kharif season of 2010 and 2011 to evaluate the new formulation of oxyfluorfen (23.5% EC) on weed control in onion and their residual effect on succeeding crops. Herbicides are being chemical in nature, excessive and repeated use may pose...
