ADAMA UK has announced that it has added two plant growth regulator (PGRs) active ingredients to its range of crop protection agrochemicals.

The active ingredients, trinexapac-ethyl and chlormequat, are registered for use on a selection of spring and winter arable crops.

ADAMA’s trinexapac-ethyl formulation is registered for use on spring and winter barley; drum wheat; grassland (seed crop); oats; rye; triticale; and spring and winter wheat.

The chlormequat formulation is registered for use on winter barley, oats, and spring and winter wheat.

Both active ingredients were marketed by ADAMA prior to the Syngenta Group merger when they were divested to third parties with an agreement put in place that ADAMA would not sell them in the UK market for a period of five years.

Now that the five-year period has concluded, the agricultural service is free to re-commercialise the products.

Commenting on the new portfolio, product manager Jonny Oosthuizen said: “With the addition of these two well-known active ingredients we are amplifying our already significant range of ethephon-based plant growth regulators to provide ADAMA’s customers with a broader range of tools with which cereal growers can effectively and efficiently manage their crops.

“As part of our portfolio growth plans, we will be looking to develop new co-formulations of both actives and will be conducting trials to assess the efficacy of ADAMA’s unique and performance enhancing formulation of trinexapac-ethyl against other standard formulations.

“We look forward to updating our trade customers and growers accordingly.”
