Although dingy cutworms have been observed in some pulse, soybean and sunflower fields in northwestern and southeastern North Dakota; warmer weather will cause cutworms to become more active. So, now is the time to get out and scout before economic feeding injury occurs.


Cutworms are an early season pest that feed on most of the field crops grown in North Dakota. They become active when the soil temperature is above 40F. Crops with lower plant populations such as sunflower, peas, or lentils are most susceptible to cutworm injury. Cutworm feeding activity usually extends from May through the end of June and young emerging plants are the most susceptible stage of crop development.
