Damage done by Hylobius abietis and Hylastes species and methods of control are briefly described. The two types of Approval for the general use of insecticides which may be issued by the Pesticides Safety Division of MAFF under the Control of Pesticides Regulations 1986 and the use of 'Application Leaflets' to convey the conditions of 'off-label' Approvals and give additional information are explained. The current status, in terms of Approval, of various possible insecticide products and applications is detailed. This Research Information Note serves as an introduction to 'Application Leaflets' on pre- and post-planting treatments published as RINs and stresses that these are issued in accordance with the statutory Approvals. Copies of the Approvals relating to pre-planting treatment with two permethrin products are included as appendices.
