Flaming as a vegetation control method began in the mid-1800s. It is based on utilizing heat for plant control, and has the potential to be used effectively for at least six agronomic crops (field corn, sweet corn, popcorn, sorghum, soybean and sunflower) when conducted properly at the most tolerant crop growth stage. There has been increasing interest in integrating flame weeding with conventional cropping systems, and where herbicide use is undesirable, such as in cities, parks and other urban areas. In this chapter, we review flame weeding requirements, the mechanism by which it reduces weeds and the potential uses of the technique. We also consider its advantages and disadvantages, including its potential environmental impacts.
