Grass Seed Insect Pest Management

Alternatives to Chlorpyrifos Research-Survey

Please help us get valuable information about chlorpyrifos 

Restrictions on the use of chlorpyrifos and the complete revocation of its registration are underway. An ODA specialty crop block-funded project involves a cross-commodity collaboration to identify viable options as alternatives to chlorpyrifos. The research will be conducted at several locations in Oregon to determine the efficacy of currently registered chemistries and newer products in onion, corn, cherries, grass seed, and clover seed.

Your responses to this survey help us identify critical issues that can improve the development of our research. Please participate in this 10-minute survey and enter for a chance to win one of ten $25 gift cards. 

If you have questions or comments about the project, please contact Silvia Rondon, Project Leader, OSU Hermiston Agricultural Research and Extension Center, 541-567-8321, silvia.rondon@oregonstate.edu. Sent on behalf of Silvia Rondon, Dani Lightle, Navneet Kaur, Chris Adams, and Stuart Reitz.

Thanks in advance for your time and feedback!

Insecticide efficacy trials

Aphids, billbugs, and sod webworm – grass seed crops

Understanding billbug species complex and seasonal phenology

Ongoing research projects in grass seed crops are funded by Oregon Seed Council,  Oregon Department of Agriculture- Specialty Crop Block Grant Program for the alternatives to chlorpyrifos research, Private Industry Partners, Eastern Oregon Kentucky Bluegrass Workgroup, and  USDA NIFA Western IPM Center.

Clover Seed Insect Pest Management

Innovative methods for the management of red clover casebearer moth in the red clover seed production systems in Oregon.

We are investigating the mating disruption methods, and developing phenology models to target adult moths. We are also determining natural enemies that are preventing this pest to reach its damage potential in Oregon. This research project was funded by Oregon Clover Commission and OSU- Agricultural Research Foundation.

Insecticide resistance monitoring in clover seed weevil in white clover production fields in Oregon. This was year two for ongoing lab bioassays for screening the development of insecticide resistance in clover seed weevil. This project was funded by Oregon Clover Commission.
