(1) Ethylene is not approved as a pesticide for use in seed potato stores under PPP regulations. However it is approved as a commodity substance for plant growth regulation in post-harvest crops under COPR (7)

(2) This formulation is not approved on ware potatoes. It was applied to seed crops, a proportion of which were later reclassified as ware

(3) This represents the total tonnage treated, not the column sum, as more than one formulation may be applied to potatoes in store
