The Use of Elevated Temperatures to Reduce the Stickiness Potential of Honeydew Contaminated Cottons

Donald E. Brushwood


Whitefly honeydew contaminated cottons were treated at different temperatures and a fixed 65% relative humidity to reduce stickiness. Two sticky cottons, provided by the USDA Ginning Laboratory, Lubbock, TX, were stored for periods of 8, 16, 32 and 48 hours at 30EC (86EF), 40EC, (104EF), and 50EC (122EF). Reducing sugars, thermodetector and minicard stickiness tests, and carbo-hydrate contents, as determined by High Performance Chromatography (HPLC) were conducted to determine effective-ness of these treatments. Fiber quality measurements in the form of Stelometer strength and colorimeter reflectance and yellowness were also determined for each treatment. Reductions in thermodetector stickiness were achieved for each temperature and treatment time, however, fiber strength was adversely affected at the two higher temperatures for one of these cottons.
