Seed control success story

Seed production was reduced by 90 per cent in a NSW Agriculture project to control wild oats.

Selective spraytopping was key to the success of this project, which aimed to improve the long-term control of wild oats in wheat while reducing overall control costs by up to 40 per cent.

The selective spraytopping involved herbicides applied at the growth transition from vegetative to reproductive. A four-year trial showed seed banks were depleted by more than 99 per cent over time. Watch for more details in an upcoming Ground Cover.
