North Central ND (06/22/17)

Information from the North Central region of North Dakota.

Parts of the NC region received some welcome rain over the last week. NDAWN stations across the North Central region are indicating an inch of rain or more for many areas of the region, however, not everyone was lucky enough to see the rainfall they would have liked. Here are some of the NDAWN reports over the past week (starting June 11, 2017): Minot: 1.39”; Mohall: 1.33”; Rugby: 1.59”; Garrison: 0.19”; Berthold: 1.03”. With precipitation comes some risk of small grain disease. Consider some scouting to observe for possible disease. The NDSU Small Grains Disease Model is also a helpful tool to estimate risk in a given area. At last check, most varieties were showing a low risk, however, a few susceptible varieties may have a moderate risk.

Canola flea beetle is continuing to cause some problems in the region. Some growers in Renville County indicated they were spraying to protect their canola from flea beetle herbivory. For most canola, it is probably past the stage at which it is susceptible. Typically, action is needed at the 4-leaf stage or younger. Once beyond that stage, the crops can withstand the feeding much better. Though, some of the northern counties had delayed planting so control may still be important to consider if economic threshold is met (economic threshold: average 25% defoliation on leaves of plant). Some minor calls regarding wheat streak mosaic virus have come into the NCREC, however, it doesn’t seem to be a widespread problem at the current time. The IPM Scouting program has also observed some tan spot in small grain fields.
