Mr. Ron Davies : To ask the Minister of Agriculture, Fisheries and Food what arrangements exist to ensure the competence of farm workers to apply pesticides ; how these requirements differ according to the pesticide in use ; and what are the different categories of such pesticides.
Mr. Donald Thompson : All people using pesticides have to be competent in their usage. Employees, and the self-employed, must have had adequate instruction and guidance in safe and efficient use. Additionally, people may not use certain pesticides unsupervised unless they hold an appropriate certificate of competence, or are working on their own or their employer's land, or are exempted by age. The arrangements are set out in the Ministers' consent to use pesticides (C(i) ) published in the Gazettes on 20 January 1989 and in "Reference Book 500 (Pesticides 1989)".
The pesticides attracting certification as a result of consent C(i) are each identified in "Reference Book 500". In brief, these are the pesticides approved for professional cultivation of crops and management of weeds. Certification thus extends beyond farm workers, but does
Column 453not cover all their activities. Pesticides approved for use as, for instance, rodenticides, or for the protection of stored products do not attract certification.
Mr. Jack : To ask the Minister of Agriculture, Fisheries and Food what steps have been taken to improve his Department's methods of responding to any public concerns on particular pesticide use or residues.
