Crop & Pest Report
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.
This week’s featured bug is the syrphid fly or hoverfly (Diptera: Syrphidae). There are about 1,000 species of syrphid flies in North America, and are common in field crops.
Although sugarbeet root maggot (SBRM) fly activity is currently at low levels throughout most of the Red River Valley (RRV), all indicators thus far suggest that some sites within the Valley will experience very high populations this year.
The Integrated Pest Management (IPM) field scouts training was conducted on May 27th at the Carrington REC. Field scouts in the IPM program will be surveying four crops (wheat, barley, sunflower and soybean) for major diseases and insect pests.
The next 7 days is expected to bring extremes in temperatures with precipitation projected to occur during three time frames.
Maps detailing corn accumulated daily growing days, percent normal rainfall, departure from normal average air temperature, and accumulated wheat growing degree days.

Cool and moist weather during the period of ash budbreak has again led to high levels of ash anthracnose, a leaf disease common to our region.
For over 40 years, the NDSU Plant Diagnostic Lab has helped individuals and professionals in agriculture and horticulture identify plant pests, diseases and cultural problems.
