Latest thinking on weed control

Greater reliance on fewer herbicides can increase the risk of herbicide resistance developing in weed populations. A new HGCA publication details the latest thinking on herbicide efficacy and weed control programmes.

A post-emergence treatment with an ALS-inhibitor herbicide is often considered essential for effective black-grass control. Due to restrictions on the number of times these herbicides can be applied, options for building durable and effective control programmes, based on a range of chemical and control options, are detailed within the publication.

Control options for annual meadow-grass and barren brome in wheat and barley in addition to black-grass in oilseed rape are also covered in Topic Sheet 116 Autumn grass weed control in cereals and oilseed rape
