Spray Calibration Training for California Red Scale 2017

On June 13, 2017, University of California Cooperative Extension Farm Advisors Ali Pourreza (Moderator), Lynn Wunderlich and Franz Niederholzer and IPM Specialist Beth Grafton-Cardwell collaborated with Matt Strmiska of Adaptiv and the Citrus Research Board to provide a training on calibration of sprayers for California red scale in citrus at the Lindcove Research and Extension Center.   More than 80 participants learned about the causes of California red scale outbreaks, the methods for calculating spray rates, and the aspects of spraying that make it most effective.  Ali Pourreza provided insights on variable-rate applications for non-uniform orchards.
