This is a rerun of an article from last year in response to several calls about slugs in cotton and soybean.  No-till, high residue, and mysterious holes in leaves should make you think slugs. They will be hiding under debris during the day. Please read below if this rings a bell!

I’ve had just a couple of call about slugs, but unfortunately the best cure still remains hot and dry weather.  There is generally little you can do in a timely manner unless you suspect in advance you are going to have a problem.  Yes, there are baits available, but you often need them on hand and be prepared to apply them ASAP.  If it takes 5-7 days to get product and apply, you’ll often discover the application is too late to help (or you can live with the damage).  Be prepared in no-till fields with high residue.  You can actually find these rascals hiding under debris before you plant.  Please refer to my several previous articles about managing slugs (linked below).  Reminder: slugs defoliate and mostly feed at night.  So a symptom of infestations are mysterious holes in leaves, and sometime, cut plants.

I’ve also had a couple of mentions of snails.  Control options would be similar to slugs.  Fortunately, snails are VERY rarely a serious threat to field crops.
