WHEAT MIDGE PLANTING RISK USING DEGREE DAYS

By the time most of you read this, we will have reached 200 DD (40EF) everywhere in North Dakota. With the wet soil and weather delays, we see ourselves now having to plant wheat at the time when heading will coincide with midge emergence. The good news is that midge populations remain low throughout most of the state. There were slight increases in midge numbers in NW and NC areas that merit watching. However, with the early vigilance, preparation, and appropriate treatment, the populations have been kept in check.

As a reminder, the midge survey map from 2000 is provided for your reference. You can also find the map and keep track of degree day accumulations at the NDSU Entomology Updates, found at:
