End Date: Aug 14, 2012
The specific approach will be to: (1) intensively sample over 100 commercial grain sorghum fields in Texas, Oklahoma, and Kansas, and use the sampling data to develop a sequential sampling technique for headworms; (2) develop attractive, and easy to understand and use, data forms for headworm sequential sampling in grain sorghum; and (3) develop an internet-based decision support system for headworm IPM that integrates products from (1) and (2) with existing IPM information needed to sample grain sorghum fields for headworms using the new sequential sampling technique. Collaborators from each of the three states will be responsible for organizing and leading the research activities to achieve (1) in their respective state. Oklahoma State University collaborators will be responsible for accomplishing (2). Collaborators from each state will provide input into development and evaluation of the internet-based decision support system, which will be developed by USDA-ARS scientists.
