In this modeling work, Gayle Somerville evaluated the value of HWSC in minimising the rate of herbicide resistance evolution. The modeling clearly showed the benefit of HWSC in minimising resistance evolution. There is a real benefit in having the diversity tactic of the non-chemical HWSC in minimising the rate of resistance evolution. HWSC reduces weed numbers over time and helps achieve greater sustainability and longevity of important herbicide resources.
Evolution of herbicide resistance in weeds is a growing problem across the world, and it has been suggested that low herbicide rates may be contributing to this problem.
