Endosulfan residues on tomatoes, potatoes, cabbages, and cauliflowers

摘要

Abstract Results are reported of residues of α- and ,β-endosulfan and endosulfan sulphate on tomatoes, potatoes, cabbages, and cauliflowers UI)der New Zealand conditions. Residues are shown to be below 2 ppm on these crops after the following waiting periods: tomatoes—2 days; potatoes—none; cabbages and cauliflowers—4 weeks. The period for tomatoes could be reduced to 1 day or less if skins were removed in processing; and for cabbages and caulifiowers to I to 2 weeks if fully trimmed of loose outer leaves. The latter treatment appears to require definition for regulatory purposes.
