The present study was undertaken to determine the persistence of acetochlor under real field conditions at maize crop. The chloroacetanilide herbicide acetochlor was applied as a pre-emergent spray on maize crop at 3 days after sowing in the experimental field in Didactical Station Ezăreni. The herbicide acetochlor was identified and quantified from soil and maize plants based on accelerated so...

In this work were investigated the physiological and biochemical responses depended on toxic effect caused by different concentrations of herbicides called as 2.4-Dichlorophenoxyacetic acid (2.4-D) herbicide in seedlings that belong to three wheat varieties. The seeds which (Triticum aestivum L. Bayraktar cv., İkizce cv. Tosunbey cv.) used plant material. 15-day old for each variety divided int...

Herbicide resistance in weeds, including corn poppy (Papaver rhoeas L.), is an increasing problem compromising global crop production. The aims of this study were to evaluate the susceptibility P. populations Poland acetolactate synthase (ALS) inhibitors and elucidate their mechanisms resistance. Between 2017 2020, 157 seed samples collected nationwide a dose-response with various ALS-inhibitin...

Herbicide mixtures are commonly used in agriculture to broaden the spectrum of weed control. The interactions or the combinations may be desirable or undesirable. Acetachlor at 150g/ha applied and ready mix application of anilofos and ethoxysulfuron at 780 g /ha provide effective control of weeds with higher grain yield. Tank mix application of metribuzin with isoproturon at 1.0 kg/ha, clodinof...

the aim of this study was to evaluate the outcomes of adding low-dose hcg (human chorionic gonadotropin), as an lh active supplement, to a gnrh antagonist protocol in patients undergoing assisted reproduction techniques. in this parallel-group randomized clinical trial, 137 infertile female outpatients aged 20 - 39 years were randomized into two groups: hcg group and non-hcg group. all patients...

‎ introduction: controversial results have been reported about the effect of morphine and stress on learning and spatial memory in rodents. there are very few studies about the effects of ultra low doses of morphine on memory. in this study, effects of acute administration of low and usual doses of morphine on memory formation and retention in the presence and absence of repeated stress were in...

In many EU countries, spray applications should comply with increasingly stringent requirements regarding the drift reduction class of nozzles. Many farmers fear that use drift-reducing nozzles producing coarse droplet spectra may compromise performance contact herbicides on small weed targets. This study examined effects various ISO 03 flat-fan (pre-orifice and single dual air induction nozzle...

Conflict between native amphibians and aquatic weed management in the Pacific Northwest is rarely recognized because most native stillwater-breeding amphibian species move upland during summer, when herbicide application to control weeds in aquatic habitats typically occurs. However, aquatic weed management may pose a risk for aquatic species present in wetlands through the summer, such as the ...

Weed management systems in almost all Brazilian coffee plantations allow herbicide spray to drift on crop plants. In order to evaluate if there is any effect of the most commonly used herbicide in coffee production, glyphosate, on coffee plants, a range of glyphosate doses were applied directly on coffee plants at two distinct plant growth stages. Although growth of both young and old plants wa...

The identification of herbicide families that act through the inhibition of amino acid biosynthesis has resulted in revolutionary progress in agricultural practices. This review describes three herbicide classes which act through this mode-of-action; including glufosinate (also called phosphinothricin, Liberty, Ignite, or Finale) which inhibits ammonia assimilation, glyphosate (Roundup, Tou...
