Yellow Starthistle Control and Preventing the Spread of Invasive Weeds - Additional Workshops(209) 533-56952013-01-22UCCE

 The University of California Cooperative Extension in cooperation with other local
agencies will be hosting a series of workshop on yellow starthistle management.
According to Scott Oneto, UC Farm Advisor and speaker, “Yellow starthistle is a
noxious weed that infests over 15 million acres in California. We have had a number
of bad years and this year is projected to be a really bad weed year. The rainfall
patterns have been ideal for yellow starthistle germination and we are encouraging
everyone to work diligently to control invasive weeds this spring”. The workshop will
cover the different management strategies for yellow starthistle ranging from
biological, mechanical, and chemical control. Other topics include sprayer calibration
and pesticide safety. The workshop will be held on the following dates and locations
throughout the region.
