The in vitro effect of five commonly used herbicides viz., pyridate, fluazifop-P-butyl, foramsulfuron, tembotrione and Smetolachlor on mycelial growth of entomopathogenic fungus Beauveria bassiana (ATCC 74040) was evaluated each at different concentrations: 100, 75, 50, 25, 12.5, 6.25 and 0% of recommended field application rate on PDA agar plates at 15 and 25°C. The herbicides tested were clas...

Switchgrass (Panicum virgatum L.) is typically slow and difficult to establish. Field experiments evaluated switchgrass establishment and the response of warm-season grass weeds (large crabgrass [Digitaria sanguinalis (L.) Scop.], broadleaf signalgrass [Urochloa platyphylla (Munro ex C. Wright) r.D. Webster], Johnsongrass [Sorghum halepense (L.) pers.], and Texas panicum [Urochloa texana (Buckl...

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...

to evaluate the effect of reduced doses of foramsulfuron and nitrogen rates on weed biomass in corn field, an experiment was conducted using split plots arrangement based on randomized complete block design with three replications at research field of ferdowsi university of mashhad, in 2011. main plots were weed control levels comprising three reduced herbicide doses of foramsulfuron (50, 75, a...

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-...

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...

Peer-reviewed research is not available to explain Polygonum aviculare L. (prostrate knotweed) control in Cynodon dactylon (bermudagrass) turf, yet P. common and troublesome managed C. turf. Six experiments were conducted determine options for golf roughs Hanover, VA. Studies evaluated hormone, photosystem, ALS inhibiting herbicides. Among a group of eighteen herbicide treatments, only six cont...

sulfonylurea herbicides mixtures with phenoxy herbicides can lead to effective control of broadleaved weeds. pot experiments were conducted to study the effect of foramsulfuron and nicosulfuron mixtures with 2,4-d plus mcpa on redroot pigweed and common lambsquarters in 2010 at the greenhouse of agricultural faculty of ferdowsi university of mashhad, iran. experiments were performed as a comple...
