Canola yield loss to green peach aphid locations
Aims

To better determine the impact of green peach aphid feeding damage in the absence of virus on canola yield and seed quality.

Key messages
  • Green peach aphid feeding damage to flowering canola did not cause yield loss.
  • Canola seed oil content also was not correlated to population density of green peach aphids.
  • Applying insecticides to control feeding damage in the absence of virus may be of little benefit and increase the rate of insecticide resistance.
