It is weed season! There is a principle in weed management that weeds are often better competitors for resources. Competition begins as soon as seeds break dormancy. The seeds that germinate first are often the ones that obtain the most resources.
Most plants have developed deep roots before they are a few inches tall (Figs. 1 and 2). Growing beans in a paper towel will highlight this point, the plant will be many times deeper than it is tall. What this means for plant competition is that if there is a plant that germinates quickly and one that germinates slowly, the slow plant will be at a competitive disadvantage.

The California Alfalfa Symposium was held last week for the first time ever in Long Beach to an audience of approximately 450 attendees. As usual, there was a wide range of alfalfa production, marketing and policy-related presentations. There were two weed-related presentations that might be of particular interest to weed practitioners and researchers. One presentation was Weed Management in Alfalfa: Where We've Been and Where We're Going by the author of this blog and another on New Herbicide Tools for Established Alfalfa by Farm Advisor Emeritus Mick Canevari. These were the best presentations of the entire conference! (Just kidding…of course.)
