Group 9B Insecticide
Mode of Action
Fulfill's unique mode of action stops aphid feeding FAST!
Fulfill doesn't act as a general toxin. The active ingredient pymetrozine protects the plant by interfering with the aphid's ability to feed. Within one to two hours of contact or ingestion of Fulfill, aphids stop feeding and therefore stop spreading PLRV.
Although aphids can remain alive for a few days, and will continue to move on the plant, Fulfill will have shut down the feeding processes almost immediately. Affected aphids stop feeding shortly after exposure, but may remain on the plant foliage until they die, which is usually within two to four days.
Fulfill is an excellent fit for any resistance management program because it represents a unique class of insecticide and it affects aphids that are resistant to other classes of insecticides.
Beneficials: Fulfill acts quickly to stop aphid feeding, but has minimal impact on a wide range of beneficial insects. Its mode of action is very specific to the feeding mechanism of aphids. In other words, Fulfill is so selective that it doesn't affect beneficial insects (even when contacted directly by spray application) such as lady beetle.
