An evaluation of seed treatments for controlling insects and diseases in canola locations

To evaluate the potential for grain yield responses from controlling insects and diseases in canola with commercially available seed applied treatments.

Key messages
  • In 2004, late sowing and dry spring conditions had a greater effect on canola yield than any disease or insects pests.
  • Jockey seed treatment provided significant control of blackleg at Alectown. However, Jockey did not increase grain yield.
  • No disease control benefits were recorded from Maxim® or Jockey canola seed treatments at Wirrinya, Gunning Gap or Red Bend.
  • Maxim seed treatment resulted in a significant grain yield increase in canola at Alectown.
  • Gaucho and Cosmos did not reduce earth mite damage to canola seedlings under very high populations at Red Bend. Other control measures are needed when earth mite populations are very high
