Isocycloseram

Isocycloseram is a newer-generation insecticide active ingredient from the isoxazoline class, developed to deliver strong control while providing a valuable tool for resistance management. Syngenta markets isocycloseram under the PLINAZOLIN® technology trademark, and it may be found in a variety of formulations and product types used by professional applicators and serious DIY homeowners, depending on registration and labeling. Isocycloseram is classified as IRAC Group 30, meaning it has a distinct mode of action compared to many legacy chemistries, making it useful for rotation programs aimed at reducing resistance in tough pest populations. It works through contact and ingestion, and is often described as providing quick feeding cessation—helping stop damage and pest activity soon after exposure—followed by control that can continue through residual performance on treated surfaces. Products containing isocycloseram may be labeled for use in a wide range of environments, which can include structural perimeter treatments, outdoor landscapes, turf, ornamentals, and other professional settings, depending on the specific product label. As with any professional-grade active ingredient, the best results come from applying it according to label directions, targeting the right pest species and life stage, and combining it with strong IPM practices like sanitation, exclusion, habitat reduction, and appropriate reapplication timing.
