Documented Uses

• Controls aphids, leafhoppers, thrips, whiteflies on rice and glasshouse crops.
• Animal Drugs -> FDA Approved Animal Drug Products (Green Book) -> Active Ingredients
• Information on 1 consumer products that contain Nitenpyram in the following categories is provided:
• Preparation: I. Minamida et al., European Patent Office patent 302389; eidem, United States of America patent 5849768 (1989, 1998 both to Takeda).
• VET: Nitenpyram inhibits the nicotinic acetylcholine receptor. It is used to treat Ctenocephalides spp in dogs and cats ... . It is toxic to fleas for only 24-48 hr and is normally used in combination with an insect growth regulator to provide continuous flea control.
• VET: Nitenpyram is indicated as a flea adulticide in dogs and cats that are, at a minimum, 2 pounds in weight and 4 weeks old. It does not repel fleas or ticks and does not reliably kill ticks, flea eggs, larvae or immature fleas. Nitenpyram may be effective for treating fly larvae (maggots) of various species. Fleas begin to fall from treated animals about 30 minutes after dosing and a single dose can protect animals for 1-2 days.
