Use pattern

Chlorfenvinphos is registered in a number of countries for use on a wide range of vegetable crops, but no uses were reported on fruit crops. Topical veterinary uses on cattle and other animals were reported for Australia.

The information on GAP supplied by the manufacturer (Anon., 1996c) was incomplete. No copies of product labels were submitted, only summary sheets. In some cases the reported PHI appeared to be inappropriate for the type of treatment (e.g. a 21-day PHI for pre-planting or pre-emergence application).

Details of registered use patterns are given in Tables 16-18.
