Range Calibration Educational Video by WRIC Davis


Dr. Joe DiTomaso (retired) and Guy Kyser of the UC Weed Research and Information Center (WRIC) present a 30-minute, six-part educational video on how to properly calibrate and apply herbicides in rangeland or wild land settings to avoid over application and still achieve effective control of target species.

The video includes:

  • Discussion and examples of major formulation categories of herbicides available in rangeland environments.

  • Demonstration on how to apply herbicides correctly with a single nozzle spray system and a multiple nozzle system (with John Roncoroni, a Napa County Farm Advisor).

  • Demonstration on how to use a wick applicator, applying herbicide on woody weeds and working in aquatic environments.
