Sticky Cotton - Causes, Impacts and Prevention. ARS Tech. Bull. 1915: 148-165. Interpretive Summary: Sampling is a fundamental component of any research program and is an essential element for accurately measuring and quantifying the characteristics of cotton lint quality for both research and commercial grading purposes. A sample is a set of individual observations (termed sample units) that allows one to make inferences about the entire population from which these observations are drawn without exhaustively observing every member of the population. Sampling activities are guided by a structured set of rules called a sampling plan or program. The sampling plan includes the designation of a sample unit(s), how these sample units are spatially allocated among potential sample units in the population, and how many sample units will be collected for each sample in order to get a reliable mean estimate. In sampling for lint stickiness there may be different goals depending on what stage the observations are made (e.g. field, gin, textile mill). Crop monitoring during the season and use of decision-making tools to aid in determining the need for sweetpotato whitefly (and/or cotton aphid) control to prevent sticky cotton development or the use of remedial actions to reduce or eliminate stickiness could potentially allow growers to produce high quality lint and avoid price penalties.
