Stored Products Research & Education Center

Research is conducted at this station by faculty, staff, and students from the the Departments of Entomology, Biosystems and Agricultural Engineering, Plant and Soil Sciences, and Agricultural Economics.  Examples of projects include insecticide trials on stored grain, fumigation studies, managing grain temperature with aeration, using automated traps for sampling insects, storing winter canola, and utilizing pheromones to monitor insects.  Educational programs are held throughout the year and include elevator workshops every spring, fumigation workshops every summer, and fumigation practicals at least twice per year.

1. Evaluation and implementation of the Electronic Grain Probe Insect Counter (EGPIC) for estimating insect infestation in grain and use of such information for IPM decision-making.
2. Simulated field trials of an attracticide (pheromone + low dose insecticide) to suppress populations of the Indian meal moth.
3. Commercial-scale disinfestations of bulk or packaged commodity using low pressure (vacuum) and flexible gas-tight storage containers.
4. Conduct yearly grain grading schools, fumigation applicator training, and elevator pest management workshops for members of the grain industry and affiliated government agencies in Oklahoma and neighboring states.

1. Electronic monitoring and automated aeration control for temperature and moisture management of stored wheat.
2. Evaluation of factors contributing to shrink and quality loss of wheat in long-term post harvest storage.
3. Field trials of new residual grain protectants for stored wheat that represent alternatives to chemicals lost due to regulation or biological resistance.
4. Field trials of a phosphine gas generator and other external application methods for effective fumigation of bulk wheat.
5. Investigate the feasibility of using controlled or modified atmospheres for disinfesting bulk-stored wheat.
6. Develop and/or evaluate rapid and accurate chemical or physical methods for detecting and quantifying internal (hidden) insect infestation in grain destined for milling.
7. Conduct studies on quality of water due to run-off from grain storage operations.
8. Develop special grain storage training courses on topics such as automated temperature management, grain quality sampling and improved application of pesticides.
