Launch of ‘What’s In Your Back Yard’ (WIYBY) new version

27 March 2018
A new version of the popular ‘What’s In Your Backyard’ (WIYBY) online tool was launched on 26 March 2018. The updated version includes maps that are easier to use than the original version.

When considering whether to use a pesticide, farmers, agronomists or sprayer operators need to be aware of risks to watercourses. WIYBY provides a straightforward way of checking if fields are in a Drinking Water Safeguard Zone (DrWSgZ) before deciding to spray. 

Paul Temple, Chairman of the Voluntary Initiative (VI), said: “I am delighted that the Environment Agency are opening a site to replace the existing version of WIYBY.  The system has really been improved with new, easy-to-use maps. If you have not done so already, I would encourage everyone to take the time to look at these maps and check whether your farm, or particular fields, sit in a DrWSgZ and, if so, to go to the VI website to find more information about what you can do to reduce the risk of pesticides getting into water.”

“It is important that everyone involved in managing a crop knows which fields have a risk of pesticides getting in to groundwater or surface watercourses. With this information, you can make an informed decision about whether an alternative, non-chemical, approach should be used or, if not, how to use good stewardship, to reduce the risk of the pesticide getting into water. WIYBY is a great, easy to use tool which can help identify DrWSgZs and the VI fully recommends its use.”
