OSR Herbicides? Think Water

OSR Herbicides? Think Water

A VI Stewardship Scheme to build on existing good practice to protect water and avoid restrictions on these products.

What's the issue?

Five key herbicides used to grow oilseed rape and control blackgrass and other weeds in arable rotations are being detected with increasing frequency in surface water. As a consequence, the UK Government is considering introducing restrictions on the use of these herbicides.

Which OSR herbicides are affected

The OSR herbicides being detected are metazachlor, propyzamide, carbetamide, quinmerac and clopyralid. Propyzamide is the most frequently detected, while quinmerac and clopyralid are more difficult for water companies to remove.

How does this affect me?

These OSR herbicides are critical to weed control and growing a successful crop of oilseed rape, some of them are also important in controlling blackgrass across the rotation. Restrictions on the use of these herbicides threatens the economic viability of oilseed rape which is a valuable break crop and a means of fulfilling the three crop rule.

So what is being done?

The Voluntary Initiative is working with water companies and the farming and crop protection industry to raise awareness of the issue, improve practices and develop new tools that will support farmers in continuing their responsible use of these herbicides.

 

What can I do to help?

There are 5 steps you can take to help


  Use Wiyby.co.uk to find out if any of your land is in a Drinking Water Safeguard Zone (DWSgZ) and understand which pesticides are of specific concern.


  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.



  Implement best practice agronomy to help protect water by following the below steps:
