Last week I sat in on the Weed Science School at held at UC Davis. This event is held every two years (alternating with the Aquatic Weed School) and is intended as a refresher or high-level introduction to weed science for professionals in the field. I always enjoy sitting in on as many of the lectures as I can because I always learn something (either completely new or previously forgotten!) from my colleagues.
Kurt Hembree (UCCE Weed Science Farm Advisor) led a breakout discussion and demonstration session on the last day of the short course where we talked about the...

Joe DiTomaso, John “JR” Roncoroni, and I evaluated a purple starthistle trial in Napa County last month. Several selective herbicides, two times of application, etc etc… one of the replications got flooded out, so I can vouch that Very High Rates of H2O are capable of controlling this weed… but the point of this post is a neat idea that JR had during the evaluation.
With digital cameras, it's become more or less routine to photograph every plot during evaluation. Sometimes it really helps with interpreting the data if you can take another look at the plots after running the statistics. But many of our plots are a long drive away, and in the meantime the sun has turned all the vegetation into...

A new weed has been identified in California rice. Its name is winged primrose willow (WPW), and it is a weed in rice fields in the southern US. So far this weed has been identified only in fields near Richvale. The Butte County Ag Commissioner is working to make sure this weed doesn't spread to other areas. The UC Davis Rice Weed Science Project and UCCE is collecting information about its biology, possible impact and management.
Don't confuse WPW with other waterprimroses, similar weeds that are usually seen around rice fields and ditches and are prostrate. WPW habit is erect, the yellow flowers have 4 petals, and the stem has wings or membranes that run longitudinally. Unlike other waterprimroses, WPW can grow within...
