the trial randomized complete block design with four replications in summer 1394 on a farm in the village of dotuyeh, kahrizak district located in the share ray to study the effects of different methods of weed control on qualitative and quantitative yield forage corn varieties (sc.704) do was. the experiment consisted of black plastic mulch, on black plastic mulch silver, mung bean living mulc...

to investigate the possibility of tank-mix application of two herbicides; nicosulfuron+ rimsulfuron (ultima 4% sc) and bromoxinil+mcpa (bromicide ma 40 % ec) for control of narrow and broadleaf weeds in corn an experiment was carried out in jiroft agricultural research centers during 2010. the experiment was conducted in a rrandomized complete block design with two-factors and four replications...

Use of efficient methods of weed control with as regards environmental sustainability as well as increased crop yield and also weed resistance to herbicides is essential. In order to, an experiment was conducted in 2012 in the Damavand jaban in Iran. Experiment treatments were compared in a split plot design by a randomized completely block design with 3 replication. The used variety of maize w...

abstract in order to efficacy evaluation of some new herbicides to control of weeds in corn, a set of field studies were conducted in 2007 at 4 province of iran, including tehran (varamin), khuzestan, fars, and kermansh. treatments were arranged in a rcbd design with four replications. treatments consisted of ultima (nicosulfuron+nimsulfuron), lumax (mesotrion+s-metolacholor+terbuthlazine), ami...

the trial randomized complete block design with four replications in summer 1394 in a farm located in the share ray to study the effects of different methods of weed control on the yield and quality of forage maize varieties (sc.704) was performed. the experiment consisted of black plastic mulch, black plastic mulch silver, vetch cover crop with a density of 100 per cent, with 50 per cent vetch...

one of the most important adverse environmental effects of herbicide application in production systems is possible damage to non-target plants, such as crops that are grown in rotation. nicosufuron+rimsulfuron (ultima) is a sulfonylurea herbicide that recently registered for use in maize fields in iran. its residues may be present more than a season in certain conditions. to measure nicosufuron...

to investigate the effect of dose and applying time of paraquat on soybean weed control, especially wild melon, factorial experiment conducted as a randomized complete block design with four replications in 2009 in dashte naz co. sari-iran. the treatments included different doses of paraquat (0, 1, 1.5, 2 and 2.5 liters per hectare of commercial material) and different growing stages of wild me...

The herbicidal properties of sulfonylureas (SU's) were first reported in 1966 (Koog, 1966). The early SU's were derivatives of triazine herbicides. George Levitt of DuPont noted that SU's having aniline as the aryl group exhibited weak plant-growth regulatory activity while the aminopyrimidine derivative displayed very high biological activity (Levitt, 1983; Sauers and Levitt, 1984). Soon compa...
