Aims

To conduct visual assessments and laboratory testing for the presence of oestrogenic clover species in 25 paddocks from 10 properties across the South East region of SA and on Kangaroo Island. 

Key messages
  • In 2017 and 2018 a total of 61 paddocks were assessed from 10 properties on Kangaroo Island (KI) and the South East (SE) of SA with 44% having the potential to cause fertility issues in ewes, with visual assessments ranking them moderate to high.
  • Whole farm assessments of the two focus demonstration farms have identified that 38% of the paddocks were moderate to high risk on the SE property and 60% of the paddocks were moderate to high risk on the KI property.
  • Producers found that identifying all four of the oestrogenic clover cultivars was difficult.
  • Undertaking paddock assessments to determine the risk rating of a paddock is time consuming for most producers.
