Herbicide options for annual legume pastures locations
Aims

To demonstrate the available herbicide options for a range of annual legume pasture varieties.

Key messages
  • Total seasonal biomass production from all of the annual pasture legumes was relatively poor as a result of the poor start. It begs the question, should Serradella, given its useful tolerance to the Imidazolinone group of herbicides, be sown with a fast growing Imidazolinone tolerant cereal such as Scope CL barley to improve early season feed production? If the season is good, the cereal could be grazed early and then sprayed out with a grass selective herbicide to stop it out-competing the Serradella later on. If the season is poor, the cereal could be left to provide valuable winter and spring feed.
  • Residues of Imidazolinone group herbicides can affect the performance of the following year’s crops and pastures, so be aware and plan ahead.
