Scouting for Worms

Over the weekend I found armyworm and black cutworm larvae in Steele County.  Its important to get out now and look for evidence of leaf feeding and/or plant cutting. Based on the cutworm monitoring network and GDU accumulation now is the time to look for black cutworms in corn.  It is important to look for both leaf feeding and cutting.  SOME fields MAY need to be treated.

Armyworms that I found were at very low levels and did NOT warrant treatment.  Here is a link on armyworms in corn:
