Encouraging research by offering financial assistance to graduate and post-graduate students who have demonstrated interest in soil-borne diseases and their control.

The Storkan Foundation, in honor of Richard Storkan - former President of TriCal, Inc., was founded in 1987 to encourage graduate research on soil-borne diseases. The name was later changed to The Storkan-Hanes-McCaslin Research Foundation in honor of the three founding members of TriCal: aforementioned Storkan, Jerry Hanes, and Bob McCaslin. The Foundation was created to further the work of the three founders who were always willing to provide time, money, fumigants, and equipment to further research in soil diseases.

The Foundation grants awards on a yearly basis. As of 2023, the Foundation has awarded a total of $628,500 to 92 students across the United States and Canada. In addition to the cash awards, the Foundation supplies airfare each year for the newly elected Fellows of the Storkan-Hanes-McCaslin Foundation, to attend the annual American Phytopathological Society (APS) meeting.
