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...

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...

Glyphosate herbicide is one the most toxic pollutants for aquatic ecosystem. Changes in serum concentrations of growth hormone (GH) and muscle protein content in O. niloticus treated with different concentrations of glyphosate herbicide under laboratory conditions were evaluated. Nile tilapia Oreochromis niloticus (mean initial weight of 57.61 ± 4.8g and initial length 14.87±1.7cm) were exposed...

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...

Gromoxone 267 SL Herbicide (GH) is widely used in weed control, and its contamination the soil has potential for agricultural land. The purpose of this study was to explore effect application soluble herbicide on changes chemical properties Inceptisols. This a completely randomized design with 4 treatments 3 replications, namely A = 0% R (0.00 mL GH 7.34 H2O); B 50% (0.03 mL-1 C 100% (0.06 HG H...

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...

Purpose: Glyphosate herbicide (GH) is a widely used and has been associated with significant mortality as poisoned cases increases. One of the reasons for high toxicity thought to be toxic effect its ingredient glyphosate. This study was designed determine differences in clinical course salt-type contained GH. Methods: retrospective conducted at single hospital between January 2013 December 201...

The Datex Capnomac Ultima monitor combines a sidestream rapid gas analyser with a spirometer. In theory the integral of simultaneous flow and oxygen concentration during inspiration is the inspired and expired volume of oxygen. From the difference between these two amounts, oxygen consumption (VO2) can be estimated. VO2 was measured in patients under general anaesthesia and compared with that o...
