The intensive global use of glyphosate has led to the evolution of glyphosate resistant (GR) weed species, including the economically damaging horseweed (Conyza sumatrensis). We evaluated the glyphosate resistance mechanisms of C. sumatrensis. While 5-enolpyruvylshikimate-3-phosphate synthase activity was similar between the glyphosate resistant (G...

Background: Eleusine indica (L.) Gaertn. (goosegrass) is globally a major weed in cropping systems. It has evolved resistance to glyphosate due to single Pro-106-Ser (P106S) or double Thr-102-Ile + Pro-106-Ser (TIPS) EPSPS target site mutations. Here, experiments were conducted to evaluate the single effect of soybean competition and its combined...

ABSTRACT Weed competition is a challenge to rice monocropping growers in the context of herbicide resistant weeds and difficult weeds to manage using chemical control. Diversifying crop rotations through integrated crop-livestock systems (ICLS) can be an alternative to face this challenge. As weed seedbank reflects management practices, this study...
Article
Even though glyphosate resistance in Chloris elata Desv. was initially reported in 2014, the resistance mechanisms have not yet been completely elucidated. Previous research found evidence of a non‐target site mechanism limiting the herbicide from reaching its enzyme target. We investigated the foliar morphology of C. elata biotypes at different le...
