By Dan Martens, Extension Educator, Stearns-Benton-Morrison Counties 800-964-4929

Click Alfalfa Field Data 05 26 2011.pdf    for Alfalfa PEAQ and Scissors-Cut samples from Thursday May 26. More results will be received on Friday afternoon and an update should be posted later Friday afternoon or evening. Then we will not have new results until Tuesday afternoon May 31.

"Continued reading" offers an note from Extension Climatologist Mark Seeley about weather prospects over the next 2 weeks and another note on "alfalfa weevil."

WEATHER: Extension Climatologist Mark Seeley Wrote May 25:
Forecast models show a significant warm-up following Memorial Weekend . Temps in the 70's maybe 80's and in 50's at night. First few days of June (1-3) should be relatively dry, followed by chances for rainfall June 4-6. Then a second longer dry period should prevail June 6-12 in most areas of Minnesota, except SE areas where passing low pressure systems will bring daily chances for
showers.  Perhaps the drier  intervals will allow getting more field work done.

ALFALFA WEEVIL: Did see some pin hole feeding in some leaves
at the legume/grass trial plot near St. Joseph on May 26. Growing Degree Days are too low yet for a large amount of hatching to have occurred yet. It will be prudent to watch for AW in second crop regrowth and following.  It is important to NOT spray for insects unless standard population thresholds are reached.  A nice summary of Alfalfa Weevil information can be found by using Google to search for "Minnesota Extension Alfalfa Weevil ".
