Herbicide Resistance: Challenges And Management Strategies
Herbicides have been used globally to suppress weeds in cropping systems. This paper attempts to a greater integration of evolutionary ideas into herbicide resistance researches. Mentioned integration, may lead researchers to become less concentrated on simply defining herbicide resistance and more operated towards a comprehensive investigation of the resistance evolution. Herbicide resistance in weeds must be minimized, because it is a major limiting factor to food security globally. Weed scientists and evolutionary biologists have to join work towards more integrated understanding of resistance. This approach will likely simplify the design of innovative solutions to the herbicide resistance challenges. Hence, chemical herbicides exert a high selection pressure on weed fitness, and diversity of weed communities change over time in response to herbicides and other strategies imposed on them. Repeated and intensive use of herbicides with the same mechanisms of action may swiftly opt for shifts to tolerant, difficult to suppress and ultimately the evolution of herbicide-resistant weeds, particularly in absence the using herbicides with different mode of actions. The argumentative hypotheses and proposals put forward are required to be laid out by field experiments. They may demonstrate to be unstable or unfounded.
