For the last couple of years, we have seen True Armyworms showing up in late May early June and causing some significant damage in sweet corn and other crops.  In the last two weeks we have caught low levels of adult True Armyworm moths in our sweet corn worm traps and are now starting to see the damage in sweet corn. 

Chuck Bornt  Even though we haven't reached super warm temperatures yet, temperatures in high tunnels, crops under rowcovers or especially those under clear plastic hoops (such as sweet corn) can get very hot on these gorgeous bright sunny days!   

The first sweet corn was planted under plastic and some under rowcovers last week which is a sure sign of spring right?  If you didn't get it done over the winter, now is the time to finish getting equipment prepared for planting season - especially calibrating your dry fertilizer units. Over time, the augers, fertilizer disk openers and other parts can get worn out, changing the amount of fertilizer actually coming out.
