Palmer amaranth, a dioecious summer annual species, is one of the most trouble‐ some weeds in the agronomic crop production systems in the United States. In the last two decades, continuous reliance on herbicide(s) with the same mode of action as the sole weed management strategy has resulted in the evolution of herbicideresistant (HR) weeds, including Palmer amaranth. By 2015, Palmer amaranth ...
Runoff from farm fields is a common source of herbicide residues in surface waters. Incorporation by irrigation has the potential to reduce herbicide runoff risks. To assess impacts, rainfall was simulated on plots located in a peanut (Arachis hypogaea L.) field in Georgia's Atlantic Coastal Plain region after pre-emergence application of metolachlor (2-chloro-N-(2-ethyl-6-methylphenyl)-N-[(1S)...
Abstract Herbicide resistance is a worldwide problem in weed control. This prompts researchers to look for new modes of action slow down the evolution herbicide-resistant weeds. research aims determine herbicidal thiazolo[3,2-a]pyrimidines derivatives, which are well known as antihypertensive drugs. The phytotoxic effects ten compounds were investigated using leaf disc discoloration test and se...
The use of glyphosate, as a post-emergence broad-spectrum herbicide in genetically modified glyphosate-tolerant (GT) cotton, supposes a big change in weed management programs with respect to a conventional regime. Thus, alterations in arable flora and arthropod fauna must be considered when evaluating their potential impacts. A 3-year farm-scale study was conducted in a 2-ha GT cotton crop, in ...
In order to investigate the effect of pre-emergence and post-emergence herbicides on nutrient depletion, weed population and nutrient uptake by wheat in sesame-wheat cropping system in Khuzestan a field experiment was conducted in randomized complete block design with three replications in the research farm of Shahid Chamran University of Ahvaz in 2019-2020. Treatments included no weeding, hand...
Herbicide resistance in weeds is a global threat to sustaining food security. In India, herbicide-resistant Phalaris minor was the major problem wheat for more than two decades, but continuous use of metsulfuron-methyl (an ALS inhibitor) control broadleaf has resulted evolution inhibitor-resistant Rumex dentatus L. This review summarizes current scenario herbicide R. dentatus, along with its ec...
in order to evaluate the effect of row space and weed management on weed population, chickpea yield and yield components, a factorial experiment based on rcbd with three replications was conducted at field research of agriculture college of lorestan university in cropping season of 2006-2007. in this research experimental factors were chickpea row spaces with four levels (15, 20, 30 and 40 cm w...
Herbicide carryover injury to rotational crops can vary in severity depending on the influence of soil properties herbicide bioavailability. Greenhouse bioassays were conducted with soybean, radish, and canola evaluate differences bioavailability three herbicides risk, atrazine, mesosulfuron-methyl, topramezone. Bioassays varying regional types nine treatment rates including a control. Plant vi...
