Marvel Ultra 120 ME Plant Growth Regulator Mode of Action

The active ingredient in Marvel Ultra 120 ME, Trinexapac-ethyl, inhibits reduction in cellular elongation and internode length. After application, new growth has shortened internodes, more tillers, and reduced vertical growth compared to untreated turf.

Trinexapac-ethyl is rapidly absorbed by the plant’s leaves and crowns. The majority of uptake occurs within one hour of treatment. Absorption through roots is negligible, as the product is broken down in the soil environment quickly. Marvel Ultra 120 ME is transported acropetally (upwards) in the xylem to the meristem, where cell elongation occurs. The systemic translocation properties of Marvel Ultra 120 ME ensures even distribution of the active ingredient within the plant tissue. Full growth regulation with Marvel Ultra 120 ME begins within 3-5 days of application.

Key Application Information for Marvel Ultra 120 ME

The rates recommended on the Marvel Ultra 120 ME label are designed to give approximately a 20 - 50% reduction in clippings over a 2 to 6 week period. In practice, the amount of growth regulation achieved will vary due to environmental conditions and turf management regimes. As a result, it is likely that application rates will need adjustment to match growing conditions, management practices and the quantity of growth regulation required.

Repeat applications can be made as soon as turf resumes growth or more suppression is desired. Marvel Ultra 120 ME growth regulator should be applied to actively growing turf, at least 6 hours before or after mowing. Good mowing practices prior to application are required to maximise performance and achieve quality turf swards. Use the lower label rate in situations when turf is going dormant due to high or low temperatures, or lack of moisture. Please consult the product label for full application details.
