Abstract
Cotton defoliation is practiced for a variety of reasons including to reduce lint trash content, for late season insect control and as a means of crop termination. In sensitive areas defoliation by conventional means may not be desirable. This study attempted to adopt a thermal defoliation device designed for viniculture to cotton. Desiccation was successful, but leaf drop was minimal. Dry steam thermal defoliation was compared to no treatment (picked green). No statistically significant difference in trash content or fiber properties was found. Seed germination was reduced 3 percent. HVI color improved slightly. More research is required before any conclusions can be drawn.
