Cyclobutrifluram

Cyclobutrifluram is an advanced active ingredient used to protect turf and ornamental plants by targeting plant-parasitic nematodes and helping reduce soilborne disease pressure. It is marketed by Syngenta as TYMIRIUM® technology, and products containing cyclobutrifluram may be used in professional programs where maintaining healthy roots and plant vigor is critical—such as golf course turf, athletic fields, lawns, nurseries, and ornamental landscapes, depending on label directions. As a chemistry, cyclobutrifluram is recognized for its high activity at low use rates and is commonly applied as a soil-directed or root-zone treatment to support healthier turf density and improved stress tolerance. It is also classified as a succinate dehydrogenase inhibitor (SDHI) and is listed under IRAC Group N-3 for nematode control and FRAC Group 7 for disease activity, giving applicators a valuable option for resistance management rotation when used properly. While specific pests and diseases vary by label and use site, cyclobutrifluram is generally positioned for long-lasting, preventive protection in high-value turf and ornamental settings, and can be integrated into broader programs that include proper irrigation, fertility, mowing practices, and rotation with other modes of action.
