Information was provided on GAP for uses on both crops animals. Information on crop uses (Netherlands, 1995; Thailand 1995; Norway 1995) is not summarized here, since the emphasis is on residues in animal products.
The most important formulations for ectoparasite control in animals are listed above. WP formulations are also available. All are diluted with water for animal treatment by dipping, spraying, wash or pour-on, and formulations as dusting powders and ear tags are also available. The most important treatment rates generally recommended are 600 mg/l for dipping cattle and for spraying cattle, sheep and goats, and 250 mg/l for dipping sheep and spraying goats.
Sheep are likely to incur the highest residues because of their wool coat and the high solubility of residues in wool grease (lanolin). Morrison (1994) demonstrated the bioequivalence of different EC formulations in sheep. This led the manufacturer to conclude that similar bioequivalence could be expected for these formulations in other species such as cattle, pigs and goats.
Although information on GAP for the use of diazinon in animal health was provided for over 55 countries and was consulted by the Meeting as needed, the summary in Table 6 below is largely confined to those countries in which supervised trials were conducted, and in some cases neighbouring countries.
