This research initiative is a GRDC investment (“Russian Wheat Aphid Risk Assessment and Regional Thresholds” project UOA1805-018RTX) that seeks to deliver information on Russian wheat aphid management for grain growers. This project is being undertaken by the SARDI and cesar. Special thanks to Fiona Tomney and Katrina Brands at Minnipa Agricultural Centre who did all the observations on these trials. |
