Abstract
Crop yield gaps, due to abiotic and biotic stresses undermine efforts to secure food for the world. Weeds are a significant biotic stress in cropping systems and can reduce productivity by 35 % to 55 % in some cases. Herbicide resistance is a compounding effect to control weeds. Non-chemical methods are being considered, especially thermal treatments, which are compatible with zero-till systems. Microwave weed and soil treatment has been shown to control weeds, weed seeds and pathogens in cropping systems. This paper explores the thermal efficiency of several thermal weed control systems, with an emphasis on microwave systems.References
