New instructional video on herbicide calibration techniques for wildland invasive plant control

Mar 10, 2012

The Weed Research and Information Center previously produced three instructional videos intended for the general public, or more specifically, the Master Gardener program. These videos focused on weed identification tools, principles of urban weed control, and urban weed control tools. In this fourth video, the emphasis is on wildland weed management. The 35+ minute video discusses the different formulations used in wildland weed management, including important advantages and disadvantages of each formulation. There are also sections on how to calibrate for single nozzle backpack sprayers using both spray-to-wet and low volume treatments, as well as boom sprayers mounted on ATVs or on backpack sprayers. In addition to foliar applications using conventional nozzles, the instructors also discuss other types of treatment techniques, including drizzle and wick applications, and stem treatments on woody plants, e.g., cut stump, stem injection, and basal bark treatments. The video is easily accessible at no cost on the wric.ucdavis.edu website. From the home page, the video can be accessed from the Online Education Programs quick links on the right hand side. Alternatively, the video can be accessed in the What’s New section of the home page.
