Help for Agricultural Producers
To help agricultural producers apply pesticides without losing chemicals to drift from wind, Clackamas County Soil and Water Conservation District is offering calibrated windsocks.
Windsocks are attached directly to the tractor for real time information to make quick, more accurate decisions on spraying practices for reducing drift. They are calibrated to indicate wind speed from 2 to 12 miles per hour.
How to Receive a Windsock
If you are a producer in Clackamas County and are interested in receiving a windsock for your sprayer, contact the District at 503-210-6002. We are happy to provide these windsocks. Producers may be asked to participate in an anonymous survey after they have used the windsocks for a number of application events. The District is partnering with the Integrated Plant Protection Center to conduct a study that will help us evaluate whether using the windsock is helping growers make better, more accurate decisions while in the field spraying.
Additional funding for pesticide reduction projects provided by Clackamas River Water Providers. Thanks to our great partner!
