Dear Weed Managers
Wednesday Feb. 15 of this week the Weed Science Society of America (WSSA) hosted a 4 hour listening session at the Tulare UCCE office conference room. In attendance were growers, consultants, ag industry personnel and university extension personnel. The WSSA is hosting 7 of these sessions around the US, the Tulare session was for the Southwestern US. The consensus was that people were aware of the difficulties that growers in the southeastern US were having with herbicide resistant weeds, but that outside of rice, herbicide resistant weeds in California are of concern but not a major problem. Worries about labor shortages, costs and regulations were of greater concern for California weed...

Yellow starthistle (Centaurea solstitialis) (YST) is the most pervasive invasive and noxious weed in California. Previous work showed that YST uses substantially more water than forage annual grasses it typically displaces. Soil moisture was 20% higher in annual grass test sites compared to YST test sites. Because yellow starthistle is found (sometimes in very extensive stands) on millions of acres of California, it is possible that removal of the thistle could substantially increase groundwater recharge and subsequent surface runoff. This could greatly improve range conditions, wildlife habitat and water supply, especially in the Sacramento Valley where groundwater levels are generally still...

Yesterday, the Weed Science Society of America honored several members for their outstanding contributions to the Society and the discipline.
Among the awardees this year was, Dr. Joe DiTomaso, Professor and Cooperative Extension Specialist at UC Davis. Joe received the Outstanding Research Award which was established to recognize research contributions in both applied and basic weed science that demonstrated originality and creativity and had an impact on the field. The Weed Science Society (and his UC colleagues) congratulate Joe DiTomaso on this award and for career-long impact and leadership.

I wanted to share some initial results from some medusahead trials I implemented this past year. Most of you are probably familiar with the invasive winter annual grass medusahead. If you follow this blog there have been numerous medusahead postings over the past years.
Now before I get going I wanted to point out this wonderful resource, The Medusahead Management Guide! It was published by the Weed Research Information Center in 2014, authored by Guy Kyser, Joseph DiTomaso, Kirk Davies, Josh Davy and Brenda Smith. There is a plethora of good information in this management guide and I encourage you to take a gander at it!
