Manitoba Agriculture’s weekly Insect and Disease Update reports relatively low insect pressure in both canola and cereals.
In canola, “Insect populations of potential insect pests are relatively low and below economic thresholds in most areas, with the exception of grasshopper populations being high around the edges of some fields,” the report says.
For cereals, “Currently there are no economic population of insects being reported in cereal crops, aside from some grasshopper control being needed. Most of the grasshopper control has been around field edges so far.”
The report does note high counts of adult bertha armyworm moths in the Elm Creek / Sperling area, and also in the area around Roblin, and also quite a few fields in the “uncertain” risk category. It reminds that when scouting canola fields, make sure to look on the ground for larvae of bertha armyworm, and currently you could look on the lower surface of the leaves for the clusters of eggs or young larvae.
