    Some bracken spraying continuing

    Bracken die-back has not occurred everywhere and it is proving possible to carry out some spraying in carefully selected areas. To ensure that the treatment will be effective, it is important to assess the condition of the bracken carefully before applying the treatment. Aerial and ground-based contractors will be able to advise.

    Bracken Die-back

    Reports from around the UK have indicated that the die-back of bracken has occurred early this year, and this will limit the effectiveness of bracken control techniques. Aerial application of Asulam has ceased and anyone planning to use ground-based chemical control application is advised to check the bracken carefully beforehand. Die-back shows itself as a browning of the tips of the fronds after full-extension and in this state, the flow of nutrients, which carries the chemical into the rhizomes to restrict next year's growth, starts to reduce.

    Use of Amidosulfuron - Natural England Position - July 2020

    Amidosulfuron products offer a potential alternative to Asulam for bracken control, but there are concerns about the impact that these products might have if used more extensively. Research is in progress, but while these uncertainties remain, Natural England will "not issue consent on SSSIs for Amidosulfuron use for bracken control except on geological sites where there are no biological features of interest."

    The full statement is available from the BCG website at:, and there is a link from the Asulam page of the website.

    Ground-Based use of Asulam - additional approval issued

    CRD has issued an additional Emergency Authorisation that will reinstate the ground-based application of Asulam for bracken control in conservation areas, and land covered by an agri-environment scheme and forestry (in the establishment phase).

    The conditions attached to this approval must be noted, and there is more information on the Asulam page of the website This page provides a link to the approval document issued by CRD, which contains full details.

    It is essential that all end-users of Asulam read and apply the conditions set out in the Approval document. This outlines the requirements to collect data to support further applications for an Emergency Authorisation in future years. There is a description of the reporting procedure that has been established on the Asulam page, and the use of the online form is encouraged, as being the quickest and easiest way to provide information. If this reporting does not take place, it is less likely that future authorisations will be granted and the prospects for obtaining the registration of Asulam to allow normal controls of usage will be diminished.

    As a positive development, resulting from a review of the use of Asulam to modern guidance and assessment criteria, CRD has changed the approved concentrations for hand-held use from 1:100 to 1:4. This will make it easier to carry out follow-up treatments, and initial treatments of small areas, using hand-held equipment.

    Asulam - 2020 Restrictions Eased

    Early indications of the response to the latest application for an Emergency Authorisation (EA) to cover the 2020 season have been received today.

    * There will be no change to the increased buffer zone to protect surface water bodies; it will remain at the increased width of 90m.
    * Ground-based application of Asulam will be re-instated on land designated for conservation or that is covered by an agri-environment scheme. This is a change: under the earlier approval, no ground-based application was permitted.

    Further Details
    * Some details have still to be decided, and the full response may not be received until next week.
    * The revised approval will be published on the BCG’s website, on receipt.
    * The definition of 'land designated for conservation' is to be agreed.
    * A revised product label is being drafted.

    Users of Asulam will be requested to complete a form to provide details of where and how the product was applied. The Chemicals Regulation Division of HSE has indicated that this information will be required to support future applications to continue the availability of Asulam beyond this year.

    It is essential that anyone planning to apply Asulam for bracken control during the coming control season reads and fully understands all the restrictions that have been agreed. If there are any queries, there is a contact form on the BCG website.

    Please circulate this information. More details will be added to the Asulam page of the website, as they come available.
