Herbicide resistance is an evolutionary event resulting from intense herbicide selection over genetically diverse weed populations. In South America, orchard, cereal and legume cropping systems show a strong dependence on glyphosate to control weeds. The goal of this report is to review the current knowledge on cases of evolved glyphosate-resistant weeds in South American agriculture. The first reports of glyphosate resistance include populations of highly diverse taxa (Lolium multiflorum Lam…

TLDR
Glyphosate-resistant weeds are a major risk for the continued success of glyphosate and transgenic glyphosate-resistant crops, however, lessons can be learnt and actions taken to achieve glyphosate sustainability.
Evolution of Glyphosate-Resistant Johnsongrass (Sorghum halepense) in Glyphosate-Resistant Soybean
TLDR
Empirical evidence establishes that the Johnsongrass survival in glyphosate-treated transgenic soybean fields from northern Argentina is due to evolved glyphosate resistance.
Agricultural impacts of glyphosate-resistant soybean cultivation in South America.
TLDR
The following actions are proposed to minimize weed resistance problem: rotation of GRS with conventional soybeans in order to rotate herbicide modes of action; avoidance of lower than recommended glyphosate rates; and keeping soil covered with a crop or legume at intercrop intervals.
Editorial Glyphosate-Resistant Weeds and Crops
Throughout the past 50 years, the quantity and quality of world food production has risen dramatically in many (but not all) countries, sustaining the world’s population despite the fact that this…

A New Approach to Weed Management to Mitigate Herbicide Resistance in Argentina
The evolution of herbicide-resistant weeds is a major concern in the corn- and soybean-producing Pampas region of Argentina, where growers predominantly plant glyphosate-resistant crop varieties and…
Investigating the potential for glyphosate resistance evolution in UK weedy species
TLDR
Investigation of the glyphosate response of three UK weedy species, Alopecurus myosuroides (blackgrass), Anisantha sterilis (sterile brome), and Arabidopsis thaliana finds potential for selection of reduced glyphosate sensitivity, which may result in compromised field efficacy.
Transgene escape and persistence in an agroecosystem: the case of glyphosate-resistant Brassica rapa L. in central Argentina
TLDR
The transgenic origin of the glyphosate resistance in B. rapa biotypes might come from GM oilseed rape crops illegally cultivated in the country or as a seed contaminant, and it implies gene flow and introgression between feral populations of GM B. napus and wild B. Rapa.
Evolution of glyphosate resistance in a Lolium rigidum population by glyphosate selection at sublethal doses
TLDR
Results indicate progressive enrichment of minor gene trait(s) contributing toward plant survival in the glyphosate-selected progenies, and the mechanistic basis of the moderate glyphosate resistance level selected by sublethal glyphosate doses remains unknown and warrants future research.

Glyphosate resistant biotypes of wild poinsettia (Euphorbia heterophylla L.) and its risk analysis on glyphosate-tolerant soybeans
TLDR
This is the first report of a glyphosate-resistant biotype in a weed species of major importance and distribution in Brazil, and the resistant biotypes were about three times less sensitive to glyphosate than the susceptible biotypes.
Absorption, translocation and allocation of glyphosate in resistant and susceptible Chilean biotypes of Lolium multiflorum
TLDR
This study takes a first approach to elucidating the mechanism involved in the resistance of one biotype of L. multiflorum selected in Chilean orchards over 8–10 years of continuous applications of glyphosate.
Investigating the mechanisms of glyphosate resistance in Lolium multiflorum
TLDR
It is reported that glyphosate resistance in L. multiflorum is conferred by two different mechanisms, limited translocation (nontarget site- based) and mutation of the EPSP synthase gene (target site-based).
Glyphosate-Resistance in Conyza canadensis and C. bonariensis
TLDR
Evaluated populations of Conyza canadensis and C. bonariensis and proved the existence of population with glyphosate-resistant biotypes, with different levels of resistance, as well as proposing alternative treatments to these biotypes.

Why glyphosate is a global herbicide: strengths, weaknesses and prospects
TLDR
Glyphosate is an exceedingly effective herbicide and presents a considerable challenge to the development of new herbicides for sustainable cropping systems and situations in which cost-effective and environmentally considerate weed control is required.
Identificação de biótipos de azevém (Lolium multiflorum) resistentes ao herbicida glyphosate em pomares de maçã
TLDR
The susceptible biotype is easily controlled by glyphosate and by the other postemergence herbicides tested, independent of the vegetative growth stage, and the resistant biotype presents low response to glyphosate, even if used in high rates, showing that some biotypes acquired resistance to this product.
Multiple Herbicide Resistance in Annual Ryegrass ( Lolium rigidum ): A Driving Force for the Adoption of Integrated Weed Management
TLDR
There are varying patterns of resistance between different biotypes of ryegrass, and populations that have developed resistance to one herbicide can rapidly develop resistance to new herbicides that are effective initially.
Glyphosate-resistant Lolium multiflorum in Chilean orchards
TLDR
A new case of glyphosate resistance in a novel species, L. multiflorum, is confirmed and correspond to the first case of Monsanto's glyphosate resistance reported from South America.
