TECHNICAL INFORMATION BULLETIN
OVERVIEW Senstar® Insecticide brings two effective modes of action for long-lasting control of soft-bodied insects, including whiteflies, aphids, psyllids, mealybugs and scales. Senstar is a suspo-emulsion (SE) formulation of the active ingredients pyriproxyfen and spirotetramat. With contact, translaminar and systemic activity that affects all life stages of targeted pests for long-lasting control, Senstar helps ensure high-quality produce from the start. SENSTAR TECHNICAL FEATURES Controls target pests at all life stages, including eggs and crawlers Provides dual systemic activity (movement in the xylem and phloem) to control pests moving into new vegetative growth, as well as pests which populate in already developed foliage Delivers translaminar movement within the foliage tissue to reach target pests that feed on the underside of leaves Selectively targets harmful insect pests with minimal impact on beneficial arthropods for excellent fit in Integrated Pest Management (IPM) programs Controls target insects in three primary ways: contact and/or ingestion, suppressing embryogenesis within insect eggs and reduction in the percent of adult female viable eggs Delivers a full rate of spirotetramat and an optimized dose of pyriproxyfen to enhance insect control MULTIPLE MODES OF ACTION Senstar delivers both Group 7C and Group 23 insecticides in a single application*. Senstar controls insect pests during their whole life cycle. Also, it delivers insecticidal properties via contact and feeding actions to put in place a comprehensive management tool in each application. Pyriproxyfen is a juvenile hormone mimic insecticide (Group 7) that delivers insect growth regulator (IGR) features, which suppress embryogenesis within the insect eggs. In addition, the IGR type of control in Senstar provides inhibition of metamorphosis and adult emergence of target insects. Pyriproxyfen has no knockdown activity on adult insects, however hatching of eggs laid by treated adults will be suppressed. Spirotetramat belongs to the Group 23 insecticides. Spirotetramat, when sprayed as a foliar treatment, breaks down into insecticidal compounds that act as inhibitors of the critical process of lipid biosynthesis among insects that feed on the treated plants. Immature insects and female adults are particularly susceptible to this path of insecticidal activity. Spirotetramat negatively disrupts the development and molting processes of insects. *Insecticide Resistance Action Committee (IRAC) Mode-of-Action Classification
