Crop & Pest Report
With all the rain this spring, blood-sucking mosquitoes are swarming and aggressively biting livestock in pastures.
Reports on Canola and Field Pea included
Some of the warmest air of the season is expected in the next 7 days, but that heat is going to hold off until early next week.
Maps detailing corn accumulated daily growing days, percent normal rainfall, departure from normal average air temperature, and accumulated wheat growing degree days.
Information from the South Central region of North Dakota.
Information from the Northeast region of North Dakota.
Color banding has been observed in small grains.

With warmer spring weather, tick season is upon us. So far, we have identified the smaller black legged tick (or deer tick), Ixodes scapularis, from Clay County, Minnesota and the larger dog ticks, Dermacentor variabilis, from areas of North Dakota and Minnesota. The Center for Disease Control and Prevention (CDC) recommends the following strategies for field workers and preventing tick bites:
Sugarbeets are actively growing and so are the weeds. I suspect most farmers are scouting their fields and preparing for postemergence weed control. I offer the following suggestions:
Question: I heard yesterday Valor does not have a dry bean label for ND anymore but OK in MN though. What am I missing here Rich?
Question: Does this look like a contact herbicide on wheat leaves? There is damage on one side of field and less as you go farther out into field. The injury is greatest along the whole field edge. The adjacent field is soybeans and I think it was sprayed prior to beans emerging. So maybe a burn down product was used, do you know what may have been used as a contact burn down product?
The following is adapted from a phone call with Dr. Kirk Howatt, NDSU Weed Scientist. Question: How soon can I make my herbicide application to my wheat and barley that have been injured by frost?
I have, or will have, 30 sites this year from Casselton to Beach to Bottineau in various studies.
We do not see the dust clouds in fields this first week of June as we did in April, but soil is moving just the same.
Most wheat fields are in the 3-5 leaf stage and have some yellow in them, especially in areas receiving near record May rains.
On Monday, we received a wheat leaf sample collected by Dr. Janet Knodel and Sam Haugen (Plant Pathology graduate student) that was confirmed as stripe rust.
Last week I wrote about evaluating corn stands to determine if replanting would be profitable. This week I will discuss the issue of stand uniformity.
Counting soybean plants just after plants are up and in the cotyledon or unifoliate growth stage is a good method to evaluate the crop stand.
Our first cereal aphids were detected in McHenry County in the NC area of North Dakota at sub-economic level, 14% incidence, on durum wheat by the IPM Scout, Jacee Aaseth. Scouting over the next month will be important for the wheat (spring, durum and winter), oat and barley.
