1. Identify if your land is in a DWSgZ

2. If you are farming in a DWSgZ, speak to your local water company catchment officer to understand the potential risk on a field-by-field basis, or speak to your agronomist

3. Where applicable, implement the following three steps to help minimise the risk of OSR herbicides reaching watercourses
