Bracken Control season moving towards a close

Under the terms of the Emergency Authorisation for the use of Asulam for bracken control, we passed the first expiry date on 16 September.  As a result of this, it is now no longer legal to sell, distribute or transfer asulam, but application can continue.  However, as bracken dies back, the effectiveness of application will reduce and application is not recommended if a significant portion of the leaves have started to turn yellow.  At this stage, the pathways to transfer the chemical to the rhizomes start to collapse.  The translocation of asulam into the rhizomes is the aim  of the exercise.

Users now have until the end of October to apply their stocks of asulam to bracken or if containers are unopened, they can be returned to suppliers.

It was good to see that Ilkley Moor is taking full advantage of the availability of asulam as shown in the article in The Wharfedale Observer.  It is a very positive sign that we have been able to secure the Emergency Authorisation for 2014 already, and I hope that this will allow plans to continue existing bracken control programmes to be drawn up early and also provide enough confidence for new programmes to be started.
