Expertise in weed control, management, biology and biodiversity

The ADAS weeds team advises on all aspects of weed management for arable, horticultural, grassland and amenity areas.

As experts in applied weed research, we conduct a range of field, outside container and glasshouse trials. We carry out desk-based research, including literature reviews and economic assessments.

Weed resistance to herbicide treatments is a growing problem

Adopting an integrated pest management approach is vital to slowing down the development of resistance. As such, we advise on management and prevention techniques using non-chemical and organic weed control. This includes innovative weed management methods, including electric weeders and precision mechanical weeding.

Our scientists are members of the Weed Resistance Action Group, an independent panel of experts dedicated to knowledge exchange in herbicide resistance research.

Weed research trials

Design, collection, interpretation and results

Our weed scientists conduct field, outdoor container, polytunnel or glasshouse contract trials. These include trials to test pesticide and biopesticide efficacy. Our field trial services include

  • Initial trial design and feasibility
  • Data collection and collation
  • Data interpretation
  • Report writing
  • Result presentation

Each trial we design is considerate of research aims. Glasshouse trials allow for the collection of precise data in tightly controlled conditions. Container trials enable the collection of data under outdoor conditions while still allowing some control. Field trials enable the collection of data in a field setting to allow comparison between different treatments.

All our weed field trials are conducted to Official Recognition of Efficacy Testing Organisations (ORETO) standards.
