Manitoba insect and disease update
By Top Crop Manager
June 18, 2014 - Cutworms continue to be an issue in some areas of Manitoba, according to the province's latest insect and disease update.
Flea beetle populations remain a concern in some areas, although the cool weather and advance of many canola fields to stages more tolerant to feeding has resulted in decreased damage.
Grasshoppers are emerging, but generally still in the first and second instar stages.
Alfalfa weevil larvae are starting to be noticed in some alfalfa fields.
On the disease side, brown spot (Septoria) and bacterial leaf blight have been observed in soybeans, and rust has been found in some fields of sunflowers.
