Summary
In this episode of Inside the Pod from the Processors and Growers Research Organisation (PGRO), host Ben Pike is joined by Dr. Becky Howard from PGRO and Joe Martin from Corteva Agriscience to discuss responsible use of propyzamide, the active ingredient in Kerb® and Kerb® Flo, a key herbicide for grassweed control in winter beans. Becky and Joe explain why propyzamide remains a crucial tool for managing resistant blackgrass and other grass and broadleaf weeds, thanks to its unique mode of action and effectiveness in cooler, moist soils. However, they also stress that increasing environmental scrutiny, particularly around water contamination risks, means good stewardship is essential to keep this vital active available. The conversation covers best practice for application timing (typically late October to December), field selection, and measures to reduce runoff, such as avoiding waterlogged soils, minimizing compaction, and maintaining buffer zones near watercourses. Joe highlights Corteva’s stewardship initiatives, including collaboration with water companies and grower support through the Kerb Weather Data app and online CPD training resources. Listeners are encouraged to visit corteva.co.uk/propyzamide for stewardship advice and weather guidance to ensure safe and effective use of propyzamide this drilling season.
