this study was conducted in 2008 at the research field of university of tehran, karaj. the experiment was designed as a randomized complete block design with three replications. treatments were: atrazine 1kg/ha, alachlor 4kg/ha, atrazine+alachlor (1+4) kg/ha, nicosulfuron 80 g ai/ha, furamsulfuron 45g ai/ha, rimsulfuron 25g ai/ha, nicosulfuron+furamsulfuron (80+45) g ai/ha, nicosulfuron+rimsulf...

Panicoid grasses are major weeds of maize and sugarcane as well as of several other important grains, including sorghum, pearl millet, and foxtail millet. Pot trials were conducted to study the activity and potential interactions of topramezone in mixture with recommended rates of rimsulfuron or nicosulfuron on three annual panicoid grasses (i.e. Echinochloa oryzoides, E. phyllopogon, and Panic...

Soltani, N., Vyn, R. J., Van Eerd, L. L., Shropshire, C. and Sikkema, P. H. 2009. Effect of reduced herbicide rates on weed control, environmental impact and profitability of corn. Can. J. Plant Sci. 89: 969 975. A study was conducted over a 3-yr period (2003, 2004, and 2005) to evaluate the effect of reduced herbicide rates 20, 40, 60, 80, and 100% of the manufacturer’s recommended rate (MRR) ...

Registered dose of herbicides may be higher than rate required for controlling weed species depending on growth stages. In order to study the effect of individual post-emergence application of 2,4-D plus MCPA and three sulfonylurea herbicides at four- to six-true leaf stage of weeds, experiments were conducted in 2011 at the greenhouse of Agricultural Faculty of Ferdowsi University of Mashh...

in order to evaluate the efficacy of some new herbicides in corn farms, a field study was conducted during the 2010 growing season in jiroft. the experimental design was completely randomized blocks, with 11 treatments and 4 replications. treatments were nicosulfuron at 2lit/ha, foramsulfuron at 2.5 lit/ha, rimsulfuron at 50 g/ha, nicosulfuron+ rimsulfuron at 175 g/ha, bromoxynil+mcpa at 1.5 li...

The pH of the spray liquid is one factors influencing efficacy herbicides. Adjusting appropriate parameters spraying may reduce consumption pesticides, which in line with currently introduced legal standards and society’s requirements. In greenhouse experiment, influence herbicides containing mesotrione, nicosulfuron, rimsulfuron, bromoxynil, a mixture mesotrione on oilseed rape control was inv...

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...

in order to evaluate the efficacy of maister 3.1% od (foramsulfuron 3% + iodosulfuron 0.1% + isoxadifen-ethyl 3%) in the control of weeds in corn fields, a series of experiments were conducted during 2010 in karaj, zarghan and jiroft. a series of rcbd design with four replications. treatments were application of a) nicosulfuron (kruz) at 2 lit.ha-1, b) bromoxynil+mcpa (bromicid m.a) 1.5 lit.ha-...

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...

Herbicides are usually applied multiple times by growers for season long weed control in Florida citrus (Citrus sp.). Rimsulfuron, a sulfonylurea herbicide has been recently registered for control of certain grasses and broadleaf weeds in citrus. To increase the weed control spectrum and reduce application cost, citrus growers often prefer to tank mix herbicides. Field experiments were conducte...
