Harvest Weed Seed Control
This is a project to explore harvest weed seed control (HWSC) under UK conditions as a method to control grassweeds and reduce the dependence on chemical control, particularly glyphosate. Previous research and experience in Canada and Australia has shown that combine-mounted seed control units (SCU) render 98% of seed that passes through the harvester unviable.
This project aims to help farmers establish reasonable expectation of what proportion grassweed is left standing at harvest and available to SCU (or other similar control measure). The project involves four farmers who have SCUs fitted to their combines, working with Will Smith (NIAB) who has drawn up a protocol for assessing weeds and efficacy of the SCU.
