Northeast ND (07/20/17)

Information from the Northeast region of North Dakota.

Soybean aphids are reported in Grand Forks County. Grain aphids are still being found on wheat, sometimes at high numbers. The crop stage is past the economical IPM threshold to spray. Small grains are ranging from milk to soft dough stage. For small grain head issues, white heads from wheat stem maggot have been found in moderate levels in a few fields. Loose smut is also being observed. Loose smut is a seed-borne disease. If levels are high in your field, avoid saving seed from those fields. Sunflowers are at R1 stage. Soybeans are ranging from R1 to R2 crop development stages.
