Asulox, over many years, has established itself as the UK’s market leading product for bracken control. The active substance, asulam, targets bracken infestations and is translocated throughout the plant to provide effective control. Herbicidal symptoms following application of Asulox are virtually absent in the year of spraying but in the following season there is little or no bracken re-growth. Completing a programme of follow up sprays with Asulox can greatly extend the bracken free period for land that has been treated.
