Crop & Pest Report

Northeast ND (07/05/18)

Information from the Northeast region of North Dakota.

It’s been a big week for fungicide crop protection applications occurring on wheat, barley and canola. IPM scouting for disease remains very quiet. Low and moderate scab risks have been indicated for susceptible spring wheat in the past week. As of Monday, we are starting to see actual scab in the spring wheat. Grasshoppers continue to be the biggest insect pest in the region. Over the weekend, I observed Colorado potato beetle eggs hatching in the Langdon area.

This time in July usually comes with hail storms. For soybeans, there is a big difference if hail hits when soybeans are at R1 versus R2 stage. Hailed-on R1 soybeans can produce good yields as long as plants don’t die or white mold infection occurs. New growth will be initiated at dormant axillary buds found where the leaves join the stem. Wait a few days, and you will notice new growth. However at R2, soybeans will take a yield reduction from the hail damage.
