Crop & Pest Report
Sugarbeet root maggot (SBRM) fly activity is currently at low levels throughout most of the Red River Valley (RRV); however, several sites within the Valley will experience very high populations this year.
This insect (life stage) was observed in garden soil in Burleigh County.
IPM Scouts have observed very low numbers of grasshopper nymphs (only 1 nymph per square yard) that have just hatched in field ditches in Cass and Barnes counties in SE ND.
The IPM (Integrated Pest Management) field scouts training was conducted on May 25th at the Carrington REC.

Growers may use the same spray equipment to apply selective herbicides in multiple crops in the spring or summer. Crop injury due to contamination is a preventable problem if the appropriate precautions are used in advance to clean spray equipment. How does it happen?
Question: I have a few clients growing SU resistant canola. I have been told they need to use Draft herbicide. In the herbicide compendium in the weed guide it says it is composed of rimsulfuron and thifensulfuron. Is this correct? I was told it contained Harmony and Express?
Glyphosate-resistant kochia has been identified in several locations across North Dakota. This raises the question as to how emerged kochia will be controlled without glyphosate.
The N rate calculators for wheat (2010), corn (2014) and sunflower (2016) are not yield-based formulas. I continually am asked how much N is needed for a bushel of ‘X’. The answer is: ‘It’s not important’.
It's important for farmers and agronomists to examine wheat plants, about 6 weeks after planting, because the plants can "tell" you a lot about their overall health, and lessons can be learned, if you know what you are looking for.
The development of wheat fungal leaf diseases (tan spot, Septoria, leaf rust) can be assessed using the NDSU Small Grain Disease Forecasting Model.
On May 23rd, stripe rust was confirmed in winter wheat research plots in Cass County (found by Matt Breiland, Research Specialist) and Adams County (found by John Rickertson, Research Agronomist, Hettinger REC).
The most common early season diseases are damping-off which may be caused by Pythium, Rhizoctonia and Aphanomyces.
Weather and crop conditions in the 2015 cropping season resulted in widespread problems with lodging in wheat, barley, and oats.
