Calibrating pesticide sprayers for best results

University of New Hampshire Extension Field Specialist Emeritus, George Hamilton will demonstrate the importance of and best techniques to calibrate air blast sprayers. Proper calibration will ensure effective, efficient, economical and legal spraying.  Inadequate spray coverage is usually the cause of poor spray efficacy and additional spray applications. Overuse of some sprays results in unhealthy residues and can lead to fines.

Calibration should be done several times each season, or when you incorporate any new equipment or repairs - from the tractor to the nozzle.  Join us for a refresher or send new employees for training.  This workshop is open for any grower that relies on either an airblast sprayer to deliver plant protectants to fruit or vegetable crops or a boom sprayer.   Please note that locations and times vary for each workshop. This is the July 18th airblast workshop. For simultaneous Spanish translation and boom sprayer calibration, please sign up for the July 19th workshop here.

Both workshops will provide audio amplification, handouts and refreshments. 

DEC Pesticide applicator recertification credits will be available in categories 1A, 22, 23, 10 for 2 credits
