Relay/Intercropping Winter Canola and Soybeans
Dr. Eric Page at Ag Canada's Harrow research station has proposed a research project on relay/intercropping winter canola and soybeans with the first planting of winter canola in fall 2021. The Ontario Canola Growers Association is keen to support this project and looking forward to working with Dr. Page on this interesting project.
Swede Midge Management Research Trials
Dr. Rebecca Hallett and her team at the University of Guelph continue their work on the establishment of thresholds for the treatment of swede midge as well the effectiveness of approved treatments.
In 2014 two wasp species (Gastrancistrus sp. and Inostemma sp.) were observed at several locations in Saskatchewan parasitising swede midge larvae within canola flower buds. More recently, another parasitic wasp species capable of parasitising swede midge was found in Quebec. Increased populations of these wasps have reduced swede midge populations throughout Ontario.
OCCA is currently supporting a research project on the conservation of parasitoid wasps to reduce swede midge populations, through the use of alternate biological control agents.
