Cutworms or wireworms? Check bare patches, and especially the interface between healthy seedlings and dead patches, to confirm the reason for missing plants. It could be cutworms, wireworms, disease or something else entirely…
-
While only a small percentage of canola fields tend to require foliar insecticides to manage flea beetles in addition to seed treatment, all fields should be monitored to assess the potential threat. Begin monitoring right after emergence and through until at least the four-leaf stage…

Smart phones and mobility-enabled tablets could be the most valuable scouting tools. But what else should be in your canola scouting kit?…
-
Insect risk maps depend on lots of scouting and survey. Each year, entomologists from the Ministries of Agriculture and Agriculture and Agri-Food Canada (AAFC) Research Centres collaborate with extension agrologists, crop specialists and industry groups to conduct insect pest surveys in field crops throughout the Prairies…
-
Insects to watch for before and during seeding and immediately after emergence are cutworms, flea beetles, leafhoppers and diamondback moth…
-
Scientific research in Western Canada has identified three factors that increase the risk of canola yield loss in short rotations. They are blackleg, clubroot and cabbage root maggot. Clubroot will drive the need for longer breaks between canola crops on more and more farms…
-
A pesticide rinsate biobed can prevent the environmental contamination of surface and groundwater by pesticides. Instead of being disposed of directly on land, at the edge of a field or elsewhere, the rinsate from the sprayer can be applied to the biobed (so it is contained)…

Think how on the ball we could be with insect management if everyone shared their scouting results? We could see hot spots flare up early in very localized areas, providing a highly valuable alert to farmers within and beside those areas. Provincial entomologists tracking insect outbreaks would welcome your input…

We had reports this week of bertha armyworm at higher numbers (maybe not at thresholds) in some very localized areas, lygus (it’s getting late), flea beetles (don’t spray them, it……
