Application

Trinexapac-ethyl as an inhibitor of the action of a key enzyme in the formation of GA1, preventing the formation of the plant growth regulator gibberllins, which promotes cell elongation.
In the absence of gibberellins the internodes of the plants fail to grow and prevent the plant from growing taller. This can be used to prevent lodging in crops and amenity turf, increase the yield in crops by redirecting energy into the production of reproductive parts and finally to reduce the frequency of mowing in turf.
Trinexapac-ethyl is approved for use on cereal crops such as barley, durum wheat, oats, rye, triticale and wheat as well as grassland, amenity turf and managed turf.
Trinexapac-ethyl is a soluble concentrate, as water dispersible granules and as a micro-emulsion, in two main concentrations-120.9 g/l and 250 g/l.
