Use pattern

Teflubenzuron is an insecticide which inhibits the biochemical synthesis of chitin. It controls all immature stages of the insects; the youngest larvae are the most susceptible and less teflubenzuron needs to be applied to control young larvae than older ones. The insecticidal activity of teflubenzuron results primarily from the ingestion of treated foliage; contact activity is less significant. The compound is also ovicidal by topical application.

Teflubenzuron controls a wide range of insect pests (lepidopterous and coleopterous larvae being the most sensitive), and some mites e.g. citrus rust mites - Phyllocoptruta spp.

The Meeting received information on GAP from the manufacturer, Germany (Anon., 1995a), Poland (Anon., 1995b), The Netherlands (Anon., 1996) and Spain (Anon., 1993). The information submitted by Spain referred to 1993 and was not taken into consideration because current Spanish GAP (March 1996) was included in the information from the manufacturer.

Table 4 shows the registered uses of teflubenzuron on all important crops and the countries where they apply.
