Herbicide Resistance

Herbicide resistance occurs when certain weeds develop the ability to survive applications of herbicides that previously killed them. This happens through natural selection: some weeds initially survive due to genetic variations, and their offspring inherit this resistance. Over time, these resistant weeds become more common, making the herbicide less effective. Resistance can develop quickly if the same herbicide is used repeatedly, emphasizing the need for integrated weed management strategies to maintain herbicide effectiveness and control weed populations.
