NORTH DAKOTA: North Dakota State University (NDSU) reports that banded sunflower moths have been found in sunflower fields.
Banded sunflower moths are a threat in all sunflower growing regions and are capable of reducing the number of seeds a sunflower produces. Be on the lookout for:
- Inadequate pollination due to larvae feeding on florets and pollen
- Silk-like webbing on sunflower heads (sign of feeding larvae)
- Empty seeds from feeding larvae
In order to combat these pests, Syngenta recommends sampling for banded sunflower moths in the early morning or late evening, when they are most active. NDSU recommends egg scouting during the R3 crop stage and setting pheromone traps to see if these insects are present in fields.
