In a wet cool year like 2009 slugs have been a menacing problem for many a corn grower.Generally speaking slugs would not normally be bothering 7 true leaf corn like that shown in these photos taken on July 7th around 7:30 PM in the evening.However with heavy residues to hide in and lots of cloud cover they have continued to be a greater concern for a longer period this year.Double click on the photos and you'll gain a greater appreciation as to how much leaf leaf tissue that they have already consumed.
Though this large 7 true leaf corn should survive this slug invasion the smaller 5 true leaf corn shown below may not be as fortunate.
The amount of leaf tissue consumed on these smaller plants is considerably curtailing their growth.
There are many plants that have suffered so much leaf defoliation that they have already died.
This field located just south of Mt Brydges along the 402 was planted in wheat residue.Though trash whippers were used to clear the wheat residue from the corn row the cooler moist soil and the wheat residue itself has served to provide a haven for slugs.There is no proven solution to control slugs.Though some growers have sprayed a 28% N solution near dusk results have been mixed as to its benefit.
