ICL has announced an update to the UK label of its residual herbicide, LockStar, which they say will provide users with more effective and flexible weed control.

The label update includes extended use of the product meaning that LockStar can now be applied all-year round instead of the previous limited window between February and June.

ICL say this will provide contractors and grounds managers with the opportunity to adapt their approach and give them greater control over weed growth.

Previously, LockStar could only be used on natural surfaces not intended to bear vegetation.

However, the new label update grants the use of the product on amenity vegetation (around). This will allow for the herbicide to be applied in a wider range of situations and be used in areas such as around the base of unsusceptible shrubs, trees, plants and other amenity areas. Full details on plant species can be found at www.icl-sf.co.uk.

The product should be applied at a rate of 500g/ha.
