“Know The Bentazone Risk” - Water Stewardship
Updated: July 2021
Environment Agency data shows that bentazone (the herbicide active substance in Basagran® SG and other products) is the most frequently detected approved pesticide in UK groundwater and is also increasingly being found in surface water. Due to the link between EU legislation on pesticides and water, it is possible that the approval for bentazone will not be renewed, resulting in the loss of all bentazone products.
Three industry leading manufacturers have formed a new partnership to help safeguard the future of the post-emergence herbicide to help maintain the approval beyond 2025. BASF, Nufarm and Sharda Cropchem have formed the “Know the Bentazone Risk” initiative which is aimed at promoting sustainable on-farm water stewardship through marketing, events, on-farm engagement, and the development of management tools.
“Know The Bentazone Risk” water stewardship programme is a proactive initiative aimed at encouraging responsible product use. Advice was updated for 2017 (and further reviewed in 2019 and 2021) to also include recommendations for surface water in addition to groundwater High Risk Areas (Drinking Water Groundwater Safeguard Zones for bentazone (DWGwSgZ) or nitrates and Groundwater Source Protection Zones 1+2 (GwSPZ)).
Identification of the high risk areas has taken a big step forward with the campaigns new Mapping and Planning Tool.
The new tool allows users to identify the level of risk in seconds and represents a big step forward in useability from the Environment Agency’s website 'Check Zones ' for DWGwSgZ & Natural England 'Magic Map ' for GwSPZ.
The “Know The Bentazone Risk” campaign asks growers and advisors to consider these updated recommendations and use the new Mapping and Planning Tool.
