Fabiatrin is used as a selective insecticide targeting specific pests in agricultural settings, particularly effective against sucking insects like aphids and whiteflies. It acts on the nervous system of these pests, disrupting neural transmission, which leads to paralysis and death. Due to its selective mode of action, it has a lower impact on beneficial insects such as pollinators when applied correctly. Fabiatrin is commonly formulated in sprays for use on crops including vegetables, fruits, and ornamental plants. Its application helps in managing resistance development in pest populations when rotated with other insecticides.
