Keeping scouting for insects, especially in crops that are slow to get going… -
The flea beetle situation seems worse than usual. The simplest reason seems the most logical: Warm and dry weather favours flea beetle emergence and activity. The same dry weather slows crop growth, leaving plants at a vulnerable small size for longer… -
Patches of missing plants will prompt farmers and agronomists to start scouting for cutworms. This scouting step is important because other factors, including dry seedbed conditions and others, can also cause patchy growth. You need to identify the cause so you make accurate action decisions… -
Scouting for the season should start right at emergence. That way you can spot some of the early-season issues featured in this week's photo quiz…

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…
