The herbicide imazamox may provoke temporary yellowing and growth retardation in IMI-R sunflower hybrids, more often under stressful environmental conditions. Although, photosynthetic processes are not the primary sites of imazamox action, they might be influenced; therefore, more information about the photosynthetic performance of the herbicide-treated plants could be valuable for a further im...
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...
Jointed Goatgrass Management with Imazamox-Resistant Cultivars in a Winter Wheatâ•fiFallow Rotation
Jointed goatgrass (Aegilops cylindrica Host) is an economically important weed in winter wheat (Triticum aestivum L.)–fallow production regions of the United States. Few options exist for management of jointed goatgrass in winter wheat due to the close genetic relationship between the two species. This research evaluated use of imazamox herbicide (2-[(RS)-4-isopropyl-4methyl-5-oxo-2-imidazolin-...
Malathion in mixture with acetolactate synthase (ALS)-inhibiting herbicides synergizes the control of weed species that have evolved metabolism-based resistance to ALS-inhibiting herbicides. However, the effect of malathion-based herbicide programs on conventional and imidazolinone-resistant (Clearfield) rice systems still need to be evaluated. Studies were conducted to determine the tolerance ...
Sunflower is an economically important oilseed crop worldwide and weeds have a negative effect on its yields. The herbicide imazamox, combined with imazamox-resistant (IMI-R) sunflower hybrids, technology known as the Clearfield production system successfully controls weeds. mechanism of action imazamox related to blocking AHAS enzyme, which catalyzes first step in biosynthetic pathway branched...
Some imidazolinone herbicides have been shown to be mobile in soil, raising concern about their possible movement to ground water. Three imidazolinone herbicides (imazamethabenz-methyl, 497 g ha(-1); imazethapyr, 14.7 g ha(-1); and imazamox, 14.7 g ha(-1)) commonly used in crop production on the Canadian prairies were applied to a tile-drained field to assess their susceptibility to leach when ...
The occurrence of multiple herbicide resistant weeds has increased considerably in glyphosate-resistant soybean fields Brazil; however, the mechanisms governing this resistance have not been studied. In its study, target-site and nontarget-site were characterized an Eleusine indica population (R-15) with to acetyl-CoA carboxylase (ACCase) inhibitors, glyphosate, imazamox, paraquat. Absorption t...
Imidazolinone-resistant (IR) wheat (Triticum aestivum L.) was released for commercial production in portions of the USA in 2002 and has provided growers with a new technology to selectively control winter annual grass weeds. Imidazolinone herbicides inhibit acetolactate synthase (ALS) in susceptible plants; however, IR wheat has an altered target site which confers resistance to these herbicide...
Abstract Downy brome is a troublesome facultative winter-annual grass weed that invades agricultural and nonagricultural lands in western North America can cause substantial crop yield losses particularly no-till winter wheat. Glyphosate-resistant (GR) downy was identified southern Alberta 2021, representing the first confirmation of GR Canada. This study designed to evaluate alternative herbic...
