Excellence Lucerne, Naracoorte SA

Adam and Wayne from Synergy Seeds are chatting with Graham Myers from Naracoorte SA. We’re looking at a new seed production stand of Excellence Alfalfa/Lucerne which is a highly winter active ten cultivar. It has a multifoliate leaf trait type for hay production. The crop has responded well after lamb grazing. For seed production it was planted at a low seeding rate and the the low crown has been great for grazing and held itself very well. Alfalfa

Lucerne Windrowing, Mid North, South Australia

Crop hygiene in lucerne seed production is critical. This shows Winter Cleaning Lucerne after the lambs have grazed it. We apply herbicides such as Spray Seed and Spinnaker with the view to be grazed again and locked up for hay. This is to remove problematic weeds that you do find in the Lucerne stands. Our quality parametres are very strong and crop hygiene. This is a good part of the weed management process for lucerne and alfalfa production.
