Slug damage to field corn was reported east of the Mississippi River in southeastern Wisconsin on June 18. In addition, three reports of possible slug-damaged soybean fields in northeast and east central Iowa were reported by Brian Lang and Virgil Schmitt, ISUE field crop specialists, over the June 20 weekend. Although slugs are only occasional field crop pests in Iowa, weather conditions this year have been favorable for slugs, and producers in eastern Iowa with high-residue, no-till fields are advised to be on the lookout. Slugs are gastropods closely related to snails and primarily feed at night or in cool, early morning hours.
