Field and laboratory experiments were conducted to evaluate the effects of conventional, Malathion 5EC, and six reduced-risk pesticides Calypso 480C, Assail 70W, Novaluron 7.5WG, SpinTor 2SC, Knack IGR, Actara 25WG, and an experimental reduced-risk insecticide labeled as GF-968, for the control of flower thrips in southern highbush and rabbiteye blueberries. The treatments were evaluated at their recommended field dosages. In the laboratory experiments, all the insecticides killed over 90% of the thrips after 24 h., Assail, Malathion and Actara acted faster than all the other compounds showing significant differences 1 and 2 h. post-application. Field experiments conducted in Alma, Georgia, for rabbiteye and in Haines City, Florida, for southern highbush blueberries showed similar results. Assail and Malathion were the most effective insecticides in reducing the population of thrips.
