A comparison of commercially available products, applied on seed or post emergent, to control Ground Lark damage in canola locations

To est alternative products to Mesurol that are commercially available both in Australia and overseas, to assess their effectiveness as bird deterrents.

Key messages
  • No bird damage was evident in the trial possibly due to the netting used which may have been a deterrent itself.
  • There was a significant effect on plant counts established in the absense of bird damage but htis didn't relate to final yield.
  • The two highest yielding treatments, although not significant (P = 0.05), were post emergent products applied to the 2nd true leaf.
