Flame treatments gave control levels similar to mechanical control, that is, good to excellent control of all weeds up to 9 days after the third application. At 25 days after the final flame application, weed control levels of alfalfa and annual rye dropped to 80 and 72% respectively. Kochia and lambsquarters control dropped to 65%. Research from Colorado State University.

Steam treatments gave little to no control of kochia, fair control of dandelion and good control of downy brome 25 days following three steam applications. Research compares hand weeding, steam weeding, and mechanical weeding in strawberries. From Colorado State University.

An important part of this research project on organic weed management conducted at the University of New England (Australia) is a mail survey of organic and bio-dynamic growers throughout Australia asking about their experiences with weed management. The first report from the survey gives some preliminary results, and a second report on the responses of Echinacea growers is also available. (Both reports linked at this site.)
