Absorption, Translocation, and Metabolism of Glyphosate and Imazethapyr in Smooth Pigweed with Multiple Resistance [PDF]

Agronomy, 2023
The evolution of herbicide-resistant weeds is the major challenge for chemical management worldwide, increasing production costs, and reducing yield. This work aimed to evaluate the putative resistance of the Amaranthus hybridus population from Candido ...

Glyphosate translocation in hairy fleabane (Conyza bonariensis) biotypes Translocação do glyphosate em biótipos de buva (Conyza bonariensis) [PDF]

Planta Daninha, 2008
The objective of this work was to evaluate the translocation of glyphosate in C. bonariensis plants resistant and susceptible to that herbicide. The 14C-glyphosate was mixed with commercial gyhphosate (800 g ha-1) and applied on the center of the adaxial

Low temperatures enhance the absorption and translocation of 14C-glyphosate in glyphosate-resistant Conyza sumatrensis [PDF]

Journal of Plant Physiology, 2019
Influence of low temperatures on the glyphosate efficacy was studied in glyphosate-resistant (R) and -susceptible (S) Conyza sumatrensis biotypes. For this purpose, the physiological and enzymatic aspects involved were characterized under two growing temperature regimes [high (30/20 °C) and low 15/5 °C temperatures day/night].

Glyphosate efficacy, absorption and translocation for Eragrostis plana control [PDF]

Advances in Weed Science, 2022
Abstract Background Glyphosate is the most effective herbicide to control the invasive and perennial Eragrostis plana in Southern Brazil. However, one application has not been sufficient to prevent the regrowth of plants.Objective: The aim of this research was to evaluate the efficacy of glyphosate sprayed alone or mixed with fluazifop-p-butyl or ...

Translocation and Root Exudation of Glyphosate by Urochloa brizantha and its Transport on Sugarcane and Citrus Seedlings [PDF]

Planta Daninha, 2019
: Glyphosate is easily exuded by the roots of plants. However, there is still some lack of information in the scientific literature as to whether Urochloa brizantha is capable of exuding glyphosate to influence the growth of crops such as sugarcane and ...

Shikimate accumulation, glyphosate absorption and translocation in horseweed biotypes [PDF]

Planta Daninha, 2015
In Brazil, few research works on mechanisms of weed resistance to glyphosate have been conducted so far. Therefore, this research aimed to study analytical procedures determining the relation between the concentration of plant shikimate after glyphosate ...

Thirty years of glyphosate-resistant crops and weeds: Current situation and future prospects. [PDF]

Pest Manag Sci
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.
