Confirm (tebufenozide) – Confirm has the same mode of action as Intrepid against lepidopteran larvae, however it has a much poorer ovicidal activity compared to Intrepid.
Lepidopteran pests
Codling moth – We have had several years of experience with Confirm
as a codling moth control. Confirm does not provide nearly the same level
of crop protection as Guthion or Imidan, even when applied at more frequent
intervals. Our experience has shown little difference in efficacy in the
timing or even rates of Confirm used against codling moth.
Leafrollers – Conifrm has efficacy against leafrollers but not as good as Intrepid. Confirm is effective against leafrollers in the spring from bloom to about 14 days after petal fall. One application of Confirm can be effective against low leafroller densities but two applications are necessary against moderate to high populations. Like Intrepid, Confirm has a long residual activity but has no contact activity.
Lacanobia fruitworm – Confirm is moderately toxic to Lacanobia in laboratory studies, but seemed to provide reasonable control in field trials.
Indirect/secondary pests
Confirm has no known effect on campylomma, leafhoppers, aphids, mites (either
phytophagous or predatory). We expect probable suppression of leafminer
similar to Intrepid but not as strong.
Pear pests
Confirm has been tested against codling moth in pear, and appears to work
effectively only against low populations. However, even at low codling
moth densities Confirm treatments sustained significant injury. Confirm
may provide acceptable control of low to moderate codling moth densities
in pear when used in conjunction with other control tactics, such as
mating disruption. Confirm does not effect pear psylla or grape mealybug.
Beneficial arthropods
Confirm has no known negative impacts on beneficial arthropods.
