March 25^th Webinar, by Coastal Viticultural Consultants, Inc.

Effective Implement for the IPM Toolbox

Improve powdery mildew management with spore trapping technology.  This technology can identify and quantify powdery mildew spores entering into or within a vineyard, better quantify overall powdery mildew pressure, and identify mildew “hot spots” before visual symptoms and damage occur. As the visual inspection of 1,000 leaves per acre is required to detect powdery mildew on leaves at an incidence level of 1% or lower (Mahaffee, et al. 2014) and Disease Forecasting Models do not reflect actual field conditions, spore trapping is more effective in monitoring and predicting powdery mildew populations and treatment needs.

Coastal Viticultural Consultants (CVC) is providing a free informational webinar (via Zoom) that will discuss the practical use and advantages powdery mildew spore trapping offers, and availability to regional data sets. The webinar will also discuss the latest research in powdery mildew resistances to commonly used treatment materials. The webinar speakers will feature Mr. Bryan Rahn president of CVC, Certified Crop Advisor, Certified Professional Soils Scientist and Agronomist, and Mr. Walt Mahaffee, PhD, Plant Pathologist at Oregon State University.   

The Webinar agenda is below:
