Second crop Alfalfa — Light PLH and Alfalfa Weevil pressure found

We finally have a nice sunny morning, and I’m out scouting some second crop Alfalfa.  I figured we should get it   scouting second crop done today with the forecast for storms tomorrow.    The Alfalfa is at 4 to 6” tall.  We found low levels of PLH (potato leaf hopper) and Alfalfa Weevil.    But with warmer temperatures these pests can advance rapidly, so I would encourage you to keep a close eye on your second crop. 

I have included a few pictures from this morning.  For some reference materials to help you identify these pests, click on the following link  AlfalfaInsectMgt by Craig Saxe.  Potato-Leafhopper-Adult

Alert! Slug Damage Found in Area Field Corn

University of Kentucky slug damage photoWith the cooler and wet weather we have seen an increase in slug activity on our young corn plants.  I have seen this mainly on early planted no-till fields in the area.   The best cure for this pest would be warm and dry weather.  Chemical control options are not known to be highly effective.   Please contact your local Allied Agronomy advisor to help check your fields now and to discuss management options.
