§ Mrs. Fenner:Since 1969, clearances for specific uses of persistent organochlorine pesticides, including DDT, dieldrin and endrin, have been withdrawn as and when suitable less persistent alternatives become available for such uses. By 1 January 1981, clearances for agricultural and horticultural purposes for all uses of dieldrin and most remaining uses of the other persistent organochlorines, including DDT and endrin, had been withdrawn. The few remaining clearances will be kept under review and withdrawn when suitable alternatives become available. Meantime, my hon. Friend will appreciate that annual usage for these remaining purposes necessarily fluctuates with the seasonal incidence of the pests concerned.
