Northeast ND (06/08/17)

Information from the Northeast region of North Dakota.

The western edge counties of Rollete and Benson are concernedly dry and uneven emergence is occurring. Oppositely, portions of Walsh County are still seeding through a wet spring. POST herbicide spraying is in high gear across the region. At the LREC, we found stripe rust in boot stage winter wheat this week. The rust is on the leaves below the flag leaf. In the northeast, there is very few winter wheat fields to target for continued rust scouting. Flea beetles pressure is winding down from peak emergence on canola. POST insecticide sprays were applied in the region. This year’s flea beetle numbers and pressure on canola is higher than last year’s. There is still canola emerging in areas that was seeded into dry seed bed which could be at risk if flea beetle populations linger. Grasshoppers are being detected in low numbers. Wireworms are active in wheat fields with known issues. Also, we found a single aster leafhopper in spring wheat field sweeps in Ramsey County.
