Yikes, my weed control didn't work! It's springtime and you're looking at your seedling alfalfa field that you planted late last fall. You have a great stand, but you're not quite satisfied with the level of weed control despite an earlier herbicide application.
Put on that jacket! This winter has been cold and dry, and many of our crops have felt it, including almonds, but also alfalfa! Fortunately, alfalfa has a high degree of tolerance but yields can also be reduced due to frost. Frost Damage.
Please mark your calendars for the annual Small Grains/Alfalfa-Forages Field Day to be held at the University of California, Davis Agronomy Field Headquarters from 8AM 4:30PM (Morning-Small Grains, Afternoon-Alfalfa/Forages). We will send out an agenda closer to the date.
