Cover Crop Termination Treatment Impacts Weed Suppression Potential

Tobacco remains an economically important crop in the state of Kentucky, and weeds are a significant challenge for tobacco producers. Weed management in tobacco is primarily accomplished with a combination of PR soil-residual herbicides, cultivation, and hand removal. There are relatively few POST herbicides for tobacco, and they provide limited control of broadleaf weeds. Winter cover crops are common in Kentucky tobacco production, and are used primarily to scavenge excess nutrients, prevent soil erosion, and weed suppression. However, growers may face trade-offs in terms of managing the cover crop optimally for weed suppression or providing optimum conditions for planting and successful tobacco establishment. This study aimed to evaluate these tradeoffs, and the impact of cover crop composition and termination method of weed control on no-till tobacco.
