Size doesn't matter: The effects of seed size and seeding rate on injury by root maggots (Delia spp., Diptera: Anthomyiidae) to canola (Brassica rapa L. and B. napus L.)

In 16 experiments at two locations over six years, seed size had no effect on feeding levels by crucifer-feeding root maggots (Delia spp.) in Brassica rapa nor in B. napus. Root maggot injury in B. rapa declined as seeding rates increased. Damage to plants grown from small seed increased as root dia...

Root maggot injury in B. rapa declined as seeding rates increased. Damage to plants grown from small seed increased as root diameter increased.
