The 2ha site has been part of a broad arable rotation for many years, which has resulted in an incredibly diverse seedbank enabling a unique opportunity for innovative research into the control of broad-leaved weeds.

This platform will then enable us to look at the specific challenges around management of specific key weeds

The control of these weeds is often taken for granted as many species are unconsciously controlled by pre-emergence programmes that target grassweeds, however the other side of the horizon is unclear, and we must prepare for the future.


As part of this partnership, this site, from which 31 weed species have already been recorded, will play host to a range of trials with the purpose of optimising the control of broad-leaved weeds in a manner which aligns with the principles of Integrated Weed Management.

“We need to get a better grasp on the changing population dynamics of broad-leaved weeds under different systems, so we will continue our work into these larger top-level changes” explains NIABs weed management specialist John Cussans, “This platform will then enable us to look at the specific challenges around management of specific key weeds”.


This will include the evaluation of combined control strategies, herbicide programmes and core concepts to maximise the herbicides that we do have. Which include application timing. “Timing of spring herbicides for broad-leaved weeds has always been tricky to get right, as each year is so different” says Nufarm Business Development Manager – Laurence Power, “We hope to build a set of data that helps growers to get these decisions right, based on the weeds that are present, size of weed and the conditions around applications”.

Regular updates of the site will be made throughout the season, culminating in a summer event to demonstrate the site when in full bloom.
