Western United States and Canada perspective: are herbicide-resistant crops the solution to herbicide-resistant weeds?

Herbicide Resistant Weeds and Crops

Modern herbicidal weed control often exploits physiological differences among plants and takes advantage of herbicide tolerance or resistance in crop plants to bring about the selective removal of susceptible weeds. The Weed Science Society of America defines herbicide tolerance as “the inherent ability of a plant to survive and reproduce after herbicide treatment” which suggests that herbicide...

Taxonomic and Life History Bias in Herbicide Resistant Weeds: Implications for Deployment of Resistant Crops

Evolved herbicide resistance (EHR) is an important agronomic problem and consequently a food security problem, as it jeopardizes herbicide effectiveness and increases the difficulty and cost of weed management. EHR in weeds was first reported in 1970 and the number of cases has accelerated dramatically over the last two decades. Despite 40 years of research on EHR, why some weeds evolve resista...

Herbicide-resistant weeds: from research and knowledge to future needs

Synthetic herbicides have been used globally to control weeds in major field crops. This has imposed a strong selection for any trait that enables plant populations to survive and reproduce in the presence of the herbicide. Herbicide resistance in weeds must be minimized because it is a major limiting factor to food security in global agriculture. This represents a huge challenge that will requ...
