'Good Clover, Bad Clover' MLA Producer Demonstration Site locations

To Increase producer awareness of the potential issues and management strategies to deal with oestrogenic clover.

Key messages

• Four oestrogenic sub clover varieties (Yarloop, Dinninup, Geraldton and Dwalganup) have been found in South East SA and Kangaroo Island pastures.
• Oestrogenic clovers can be responsible for reduced ewe fertility, difficult births, prolapse of the uterus, urethral blockages in wethers and udder development in maiden ewes and wethers.
• Growers are encouraged to assess their own paddocks for the presence of problem species, potential impact on their flock and the development of appropriate management strategies
