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!

To provide quantitative information on pesticide loadings from the Sacramento and the San Joaquin watersheds into the Sacramento-San Joaquin Delta waterways using the Soil and Water Assessment Tool (SWAT).
- Set up the SWAT model for the Sacramento and the San Joaquin watersheds
- Calibrate and validate the model for streamflow, sediment and pesticide simulation
- Quantify pesticide loadings into the Delta using the calibrated SWAT
- Explore the possibility of simulating nitrogen load to the watersheds.
We are in the midst of a new and changing era of Worker Protection Standards (WPS). The U.S. Environmental Protection Agency (EPA) and the California Department of Pesticide Regulation (DPR) recently published the revised WPS, which is meant to increase protections for agricultural fieldworkers and pesticide handlers from pesticide exposure when they're working in farms, forests, nurseries and greenhouses. The changes are already affecting California agriculture!
What major regulatory changes have already gone into effect?
Several changes are required to have been in place as of January 2, 2017. These include:
- All 417,000 fieldworkers in California must attend annual pesticide safety...

Meet Our New Cross County Weed Science Advisor: Pratap Devkota, Ph.D
Dr. Pratap Devkota earned his Ph.D in Weed Science at Purdue University. While working on his Ph.D, he worked as a Graduate Research Assistant for dissertation research which evaluated the influence of spray water quality factors on herbicide efficacy. Evaluating the interaction of foliar fertilizers with herbicide and the use of adjuvants for improving herbicide efficacy were also part of his Ph.D research.
Additionally, Devkota received his MS degree in weed science from the University of Arkansas where he worked for weed.../h3>

*Chuck Ingels is a Farm Advisor with the UC Cooperative Extension Capitol Corridor, Sacramento County office.
According to the 2014 USDA-NASS Organic Survey, Washington State was the largest U.S. producer of organic apples, harvesting 429 million pounds (over 90% of U.S. fresh production) from about 14,000 acres, with an estimated farm gate crop value of $210 million. In Oct. 2016, I spoke at an organic orchard floor workshop held in Wenatchee, WA, that covered organic weed and nitrogen management (view a PDF of the...
