Glyphosate and 2,4-D have been commonly used for control of common giant ragweed before planting corn soybean in the midwestern United States. Because these herbicides are primarily applied early spring, environmental factors such as temperature may influence their efficacy. The objectives this study were to (1) evaluate on efficacy or glyphosate level resistance (2) determine underlying physiological mechanisms (absorption translocation). Glyphosate-susceptible (GS) glyphosate-resistant...

Abstract Pollen-mediated gene flow (PMGF) refers to the transfer of genetic information (alleles) from one plant another compatible plant. With evolution herbicide-resistant (HR) weeds, PMGF plays an important role in resistance alleles HR susceptible weeds; however, little attention is given this topic. The objective work was review reproductive biology, studies, and interspecific hybridization, as well potential for herbicide economically broadleaf weeds including common lambsquarters,...

Giant ragweed is one of the most competitive annual broadleaf weeds in soybean production fields midwestern United States and eastern Canada because its early emergence, rapid growth rate, high plasticity, resistance to glyphosate acetolactate synthase inhibitors. Therefore, early-season management giant critical avoid yield loss. The objectives this study were evaluate control glyphosate-resistant through integration preplant tillage or 2,4-D; PRE POST (EPOST) followed by (fb) late (LPOST)...

Glyphosate-resistant (GR) giant ragweed is a problematic broadleaf weed in crops including maize and soybean the Midwestern United States. Commercialization of with 2,4-D or dicamba glufosinate resistance will allow post-emergence (POST) applications these herbicides. Therefore, information needed on how 2,4-D/dicamba interact various rate combinations. The objectives this study were to evaluate interaction plus and/or for control GR ragweed, determine their effect density, biomass, injury,...

Summary Glyphosate‐resistant Ambrosia trifida is a competitive and difficult‐to‐control annual broad‐leaved weed in several agronomic crops the Midwestern United States Ontario, Canada. The objectives of this study were to compare treatments for control glyphosate‐resistant A. with tillage followed by pre‐emergence (PRE) and/or post‐emergence (POST) herbicides maize determine impact escapes on yield. Field experiments conducted 2013 2014 grower fields infested . Tillage prior sowing resulted...

Abstract The herbicides that inhibit very-long-chain fatty acid (VLCFA) elongases are primarily used for residual weed control in corn, barley, oat, sorghum, soybean, sugarcane, certain vegetable crops, and wheat production fields the United States. They act by inhibiting shoot development of susceptible species, preventing emergence growth. objectives this review were to summarize 1) chemical family VLCFA-inhibiting their use States, 2) VLCFA biosynthesis plants site action, 3)...

A Palmer amaranth (Amaranthus palmeri S. Watson) biotype has evolved resistance to photosystem (PS) II- (atrazine) and 4-hydroxyphenylpyruvate dioxygenase (HPPD)-inhibiting herbicides (mesotrione, tembotrione, topramezone) in maize seed production fields Nebraska, USA. The objectives of this study were determine the effect soil residual pre-emergence (PRE) followed by (fb) tank-mixture foliar active post-emergence (POST) on PS-II- HPPD-inhibitor-resistant control, yield, net economic...

Abstract Herbicide resistance has emerged globally as a serious threat to profitable crop production. FMC promotes integrated weed management approaches including responsible use of existing herbicides, non‐herbicide control tools, awareness about herbicide issues, and support initiatives. is dedicated developing sustainable solutions through the discovery new herbicides with novel sites‐of‐action, effective formulations, advanced application technology, proactive monitoring for resistance....

To investigate the unique challenges faced by older women during COVID-19 pandemic regarding social connection, feelings of loneliness, and their subsequent impact on mental health well-being.

Common ragweed is an important broadleaf weed in agronomic crops the northcentral United States. A common biotype glyphosate-resistant (GR) soybean production field southeast Nebraska was not controlled after sequential applications of glyphosate at labeled rate. The objectives this study were to confirm GR by quantifying level resistance greenhouse and whole-plant dose-response studies evaluate response putative POST corn herbicides. Greenhouse confirmed 7- 19-fold compared known...

Ganie, Z. A., Stratman, G. and Jhala, A. J. 2015. Response of selected glyphosate-resistant broadleaved weeds to premix fluthiacet-methyl mesotrione (Solstice™) applied at two growth stages. Can. Plant Sci. 95: 861–869. A (1:17.5 ratio) has recently been registered for post-emergence (POST) broadleaf weed control in corn. The objective this study was determine the response common waterhemp, giant ragweed, kochia a when 10- 20-cm-tall plants. Greenhouse dose studies were conducted...

A field experiment was conducted to quantify pollen mediated gene flow (PMGF) from glyphosate-resistant (GR) glyphosate-susceptible (GS) giant ragweed under simulated conditions using glyphosate resistance as a selective marker. Field experiments were in concentric design with the GR source planted center and GS receptors surrounding eight directional blocks at specified distances (between 0.1 35 m cardinal ordinal directions; additional 50 for directions). Seeds of harvested receptor total...

Common ragweed is a weed in the midwestern United States and eastern Canada that difficult to control due evolution of an important resistance multiple herbicides including glyphosate. Recently, common biotype with 19-fold glyphosate was confirmed Nebraska.

A lower amount shikimate accumulated GR (≤65 μg...

Giant ragweed is one of the most competitive annual broadleaf weeds in corn and soybean crop production systems United States eastern Canada. Management giant has become difficult due to evolution resistance glyphosate and/or acetolactate synthase (ALS)-inhibitor herbicides ragweed’s ability emerge late season, specifically Corn Belt. Late-season herbicide application may reduce seed weed species; however, information not available about late-season applications on production. The objective...
