NICHOLAS SEITER UPDATES
Reports of insect activity so far have focused on large/early flights of black cutworm and true armyworm, likely helped along by storms out of the southwest a couple of weeks ago. Both species are more likely to be a problem if dense vegetation is present in the field; black cutworms are especially attracted to winter annual weeds, while armyworm prefers dense grassy vegetation. Be on the lookout for seedling pests (including seed corn maggot, slugs, wireworms, etc.), which can become a problem when cool conditions delay emergence.
