Herbicide use increases weed resistance – and costs, new study finds

Lead author of the study Rob Freckleton, Professor of Population Biology from the University of Sheffield, said: “The results were simple: farms that used a greater volume of herbicide had more resistance.

“Beyond this we found little evidence for a role of any other management techniques: neither the diversity of chemicals used – for example whether farmers used a variety of herbicides or just one – or diversity of cropping mattered, despite both being advocated as methods to reduce the evolution of resistance.”

Xenobiotic chemicals – such as herbicides, fungicides, insecticides and antibiotics – are used in both agriculture and healthcare to manage pests and diseases. However, resistance has evolved to all these types of xenobiotics, rendering them ineffective, with serious consequences for crop production and health.
