The objective of this research was to evaluate the efficacy of various pre-emergence (PRE) and post-emergence (POST) herbicides for the control of volunteer adzuki bean (Vigna angularis (Willd.) Ohwi & Ohashi) in soybean (Glycine max L.). Trials were conducted at two locations in 2005, 2006, 2007, and 2009. Experiments were arranged in a randomized complete block design with either five PRE or ...

Experiments were conducted during the summer of 2002 at the Rice Research and Extension Center, Stuttgart, AR, to evaluate: 1) various timings of sequential applications of imazethapyr at 0.063 lb/acre (4 oz Newpath/acre) in conventional and staleseedbed rice planting systems utilizing Clearfield ‘CL-161’ and 2) the timing of clomazone application at various rates and timings in conventional ri...

field experiments were conducted in zanjan, markazi, esfahan, and chaharmahal va bakhtiari provinces to evaluate imazetapyr herbicide efficiency for weed control in common bean (phaseolus vulgaris l.) in 2006. there were four replications at each site and treatments were arranged in a randomized complete block design. in zanjan, maximum weed biomass reduction by 91 and 88 percent were achieved ...

The objectives of this study were to evaluate the efficacy of pendimethalin applied pre-emergence (PRE) followed by post-emergence (POST) application of imazethapyr + imazamox/quizalofop-p-ethyl for weed control and their effect on conventional soybean injury, yield attributes, and yield. Field experiments were conducted in 2013 and 2014 in conventional soybean. Herbicide treatments provided ≥9...

a field experiment was conducted in khorramabad to evaluate the efficacy of 12 herbicides [ethalfloralin (3 l.ha-1), trifloralin (2 l.ha-1), pendimethalin (1.5-2.5 l.ha-1), imazethapyr (0.5-0.7 l.ha-1), isoxaflotole (80 g.ha-1), pyridate (2.5 l.ha-1), bentazon (2 l.ha-1), metribuzine (0.7 kg.ha -1), fomesafen (1 l.ha-1), simazine (80 g.ha-1), prometrine (830 g.ha-1), haloxyfop-r-methyl (1 l.ha-...

to determine the optimum weed management method and plant population density on chickpea yield, a split plot experiment based on rcbd with four replications was carried out at the university of tehran research farm (located in karaj) during 2010-2011. the main factor consisted of nine treatments including: 1. trifluralin pre-plant, 2. pendimethalin pre-plant, 3. complete weeding, 4. imazethapyr...

This safening effect appear...

An imidazolinone-tolerant wheat (Triticum aestivum L. em Thell) mutant in the winter wheat cultivar Fidel has been identified and characterized. The mutant was isolated from a population derived through seed mutagenesis of the variety with an aqueous solution containing sodium azide. Imidazolinone-tolerant wheat seedlings were selected from the M(2) generation of the population in the presence ...

Naphthalic anhydride is a seed-applied herbicide safener which reduces the toxicity of ima­ zethapyr, an imidazolinone herbicide, to maize (Zea mays L.). Protection of maize from ima­ zethapyr was dependent on the amount of naphthalic anhydride applied to the seed. M etabo­ lism of imazethapyr by maize roots and shoots was increased by exposure of the roots to a solution containing naphthalic a...

Imazethapyr is a broad spectrum herbicide used as early post-emergence in pulses, oilseeds and leguminous crops. Imazethapyr is an imidazole compound used as a selective herbicide. The compound controls weeds by reducing the levels of three branched-chain aliphatic amino acids, isoleucine, leucine and valine, through the inhibition of aceto-lactate synthase (ALS), an enzyme common to the biosyn...
