The United States Environmental Protection Agency (U.S. EPA) recently published the revised Agricultural Worker Protection Standard (WPS). The WPS is meant to increase protections for agricultural fieldworkers and pesticide handlers from pesticide exposure when working in farms, forests, nurseries and greenhouses. The changes will definitely affect California agriculture, and soon-- as early as January 2017 in some cases.
What major regulatory changes are in store for us and when will they happen?
Several changes are required to be in place by January 2, 2017. These include:
- All 417,000 fieldworkers in California must attend annual pesticide safety training.
- Records of...

Invasive aquatic weeds hinder access to marina docks and slips in the Sacramento / San Joaquin Delta, resulting in costs for management and potential lost business for marina operators.
Water hyacinth collects around slips and docks and other structures in the water. If not removed or treated, the weeds continue to grow. By late summer, water hyacinth and other weeds can block marina entrances, damage boat propellers, or even shut down marinas.
Because marina operators cannot spray herbicides to manage invasive weeds, they must rely almost exclusively on manual labor to remove invasive weeds. How this is done depends on the marina and the size of the...

Several years ago, I had what seemed like a great weed research idea.
My idea addressed a serious agricultural weed problem in California, it was applicable to several cropping systems, it used an integrated approach to weed management, and it utilized a pretty novel approach (or so I thought). I proudly laid out this idea to my UC weed science colleague at a meeting, only to hear "That's great Brad but I think your predecessor tried that in the late 80's and it didn't work very well". After my damaged pride recovered a bit, I started thinking about the volume of research that we do that is not very easy to find out about after it is done.
As scientists, we often think about...

Many of the ranchers I've spoken with over the last year and a half have said that tumbleweed, also known as Russian thistle (Salsola sp.), is a big problem in both San Benito and Monterey counties.
Local ranchers have said that tumbleweed is
- a much bigger problem in drought years and doesn't come up as much in wet years
- eaten by cattle when it is young
- a summer annual and is likely to be more wide-spread in areas that are not grazed in summer (because cattle aren't there to control it when it starts growing more quickly)
- more widespread in steep areas or other areas that are inaccessible to cattle
Since limited research has been conducted on control methods for...
