Research Project: SEQUENTIAL SAMPLING AND IPM DECISION AIDS FOR HEADWORM IN GRAIN SORGHUM
2012 Annual Report


1a.Objectives (from AD-416):
The objective of the proposed research is to develop new, improved sampling and IPM decision-making tools for sorghum headworm in grain sorghum in the Great Plains. The new technology will reduce sampling time, increase the reliability of IPM decision-making, and reduce producer costs (thereby increasing profits).


1b.Approach (from AD-416):
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.


3.Progress Report:

The specific approach was 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 objectives 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 were responsible for organizing and leading the research activities to achieve objective 1 in their respective state. Collaborators from each state also provided input into development and evaluation of the internet-based decision support system, which was developed by USDA-ARS scientists. The West Texas A&M University collaborator successfully completed her contributions to the project, and all project objectives (objectives 1-3) are now complete.
