The Eco-Evolutionary Imperative: Revisiting Weed Management in the Midst of an Herbicide Resistance Crisis

摘要: Modern weed science is at a crossroads. Born out of advances in chemistry, it has focused on minimizing competition with genetically uniform crops and heavy reliance herbicides. Paradoxically, the success obtained such an approach reluctance to conduct integrated multidisciplinary research resulted unintended, but predictable, consequences, including selection herbicide resistant biotypes. Advances eco-evolutionary biology, relatively recent discipline that seeks understand how local population dynamics arise from phenotypic variation resulting natural selection, habitat distribution, propagule dispersal across landscape are transforming our understanding processes regulate agroecosystems. Within this framework, complementary tactics develop alternative management programs include following: (1) scientists must recognize evolution occurs within crop fields ecologically-relevant time scales rooted inherent exists all populations; (2) should probability mutant directly related size; (3) farmers need acknowledge resistance transcends any one farm coordinate practices regional actions; (4) incentives be developed implemented help adoption programs; (5) risk analysis can incorporate perspective into programs.
