In June, 2014, 30 growers attended a spray coverage demonstration in a potato field in Alliston, Ontario. Our goal was to explore three questions: What is the effect of droplet size on coverage? What is the effect of volume on coverage? What is the effect of spray angle on coverage? This certainly wasn’t a scientific experiment. […]
Reproduced from an article written by Angela Lovell for Grainews, 2014 “The fundamental challenge of spraying is that it’s a compromise game,” said Tom Wolf of Agrimetrix Research and Training. “As operators and advisors we need to always balance the opposite needs of coverage, efficacy and drift.” Wolf, in a presentation at the recent Manitoba […]

To understand the reasons why, and help applicators use the right volume for a given situation, we briefly outline what happens to a spray cloud as it reaches the crop canopy. Basic Principles […]
