Thomas would carry out a farm visit to review existing practices. These visits aim to promote best practice and identify suitable improvements and recommendations you can undertake on your holding. Many of these recommendations may be eligible for our Pesti-wise infrastructure and equipment grants if you farm within the Roxwell Brook target area:

Within the Roxwell Brook catchment, Thomas will discuss best practice with users of metaldehyde and other pesticides, with an objective to reduce peak pesticide concentrations at the sub-catchment level and to raise awareness of the issues that these actives present to Essex & Suffolk Water.

In support of this work, we are monitoring pesticide concentrations in the Roxwell Brook and a control catchment to evaluate the success of the Pesti-wise project.

At the level of the Chelmer and Blackwater catchment, we will continue to undertake “abstraction management” each autumn to actively try to take water from the rivers when metaldehyde concentrations are lowest, to continue to ensure we provide our customers with clean, clear water that tastes good.
