Using the exposure assumptions described in this unit, EPA has concluded the combined food, water, and adult post-application dermal exposures result in aggregate MOEs of 761 for liquid products and 601 for granular products. 2023 United States Golf Association.

The plant growth regulator trinexapac-ethyl (TE) is widely used to increase seed yield by reducing lodging in many grass species, including perennial ryegrass (Lolium perenne L.) and tall fescue (Festuca arundinacea Schreb. Lodging occurs due to a variety of factors, and as shown in the figure below, the timing of lodging will determine the final impact on grain yield.
