Crop
injury from Slugs is by defoliation of established stands that delays
crop development. Slugs use their tooth-covered tongue (radula) as a rasp to
scrape tissue from leaf surfaces. Freshly damaged plant surfaces will often show
a telltale dried slime trail that was deposited as the slug moved across the
leaf. Damage to plants appears as streaks or holes on leaves. If you find
suspected slug damage, look for the slugs in and under crop residue during the
day, especially at the base of last year's corn stalks.
