A comparison was made between this survey and another, independent survey compiled from sales returns for all of New Zealand. Twelve classes of pesticides were compared and there was good agreement between the two surveys, with the exception of data for non-selective weedkillers (which include amitrole and glyphosphate). About 3 thousand tonnes of pesticide active ingredients were applied annually in the North Island, with 57% of this being herbicide and the remainder equally divided between fungicide and insecticide. On average, 3-19 kg/ha yr of insecticides, and 6-20 kg/ha yr of fungicides, were applied to horticulture.
