Summary: |
Infestations of root maggots (Delia spp.) (Diptera: Anthomyiidae) and flea beetles (Phyllotreta spp.) (Coleoptera: Chrysomelidae) were assessed for Polish (Brassica rapa L.) and Argentine (Brassica napus L.) canola grown under conventional and zero tillage regimes, with three different row spacings (10, 20, and 30 cm), and three seeding rates (5.0, 7.5, and 10.0 kg - ha-1). The study was conducted at two sites in central Alberta: near Vegreville and approximately 35 km northwest of Westlock. |
