Darkan, WA
Aims
To monitor how wild radish populations change under a range of integrated weed management (IWM) methods
To investigate the economic advantages to spraying versus hand weeding.
Key messages
An integrated weed management (IWM) approach was used incorporating integrated Harrington Seed Destructor (iHSD), herbicide, hand picking, crop rotation and early grazing opportunities
After seven years wild radish numbers were controlled on paddocks that previously had high densities
Between 2018 and 2020 the radish population was reduced by 71%
