Central MN Alfalfa Scissors-Cut Data June 13, 2013

by Dan Martens, Extension Educator, Stearns-Benton-Morrison Counties

Posted Originally June 13 Evening; UPDATE June 14 about 9:45 a.m. Note to watch potential insect issues.
The "PDF" document listed here is information from field observations and lab tests we have so far from June 13. We may get a couple more reports on Friday and then I will aim to update the PDF posted here later in the day on Friday. I will note the UPDATE time.

The weather clearly drives decisions now. Making the best of it still counts. Weather looks a LITTLE more hopeful.

Wide Swath? Maybe not THAT wide. Regional Extension Educator Doug Holen offered today that farmers have told him that with wet soil conditions, they lay the swath as wide as they can without driving on it. Pressing hay into soft ground is not a good deal, nor is tracking mud up on the swath. Thanks, Doug... and farmers who shared this.

Alfalfa Weevil? Could be. There are a couple of notes at the end of the June 13 Field Data pdf related to alfalfa weevil larva (AWL) and potato leafhoppers. We should be on the watch for both through second crop harvest. AWL could be an issue with second crop regrowth.  There is a growing degree day monitoring map for AWL. Local conditions could vary. Take a look at thermal models for alfalfa weevils from the University of Wisconsin. Other models are available at

LATE AND PREVENTED PLANTING: Check other news items posted here for links to a wider variety of information about late and prevented planting issues. Corn silage is still the best forage option for any of the corn silage that people still need to plant for the coming year.
