An AHDB research project looking into the management of aphid and BYDV risk in winter cereals is set to receive a three-year funding boost. CPM reports. Up to £190,000 is available for AHDB’s latest three-year project, which aims to develop targeted control of the main virus vectors – bird cherry–oat aphid and grain aphid. It forms part of a strategic investment in work on barley yellow dwarf virus (BYDV) risk and integrated pest management (IPM) strategies in cereals. As part of a current 12-month pilot study, the feasibility of a field-specific decision-support system for BYDV is being investigated. Due to report in the autumn, the work includes an industry survey which received 200 responses showing strong support for research in this area. In particular, 93% of respondents cited the development of an autumn treatment threshold for aphids as a priority. Interim results from the pilot work have helped to shape the current call, which focuses on monitoring and decision support. Currently, AHDB provides two key monitoring tools: Aphid News, which indicates the levels of cereal aphids flying across Great Britain, and a BYDV management tool, which estimates aphid development to guide spray decisions. Such tools can focus monitoring efforts but…
