Assessing water sensitive paper – Part 3
This is the final part of our three-part article discussing methods for digitizing and processing water sensitive paper. You can read part one here and part two here. Morphological operations We can now move on to the larger shapes, or “morphology” of the objects in our binary image. Our goal is to quantify deposits by […]

Riparian vegetation or low-drift nozzles for water protection?
Authors: T M Wolf, B C Caldwell and J L Pederson. Originally published in Aspects of Applied Biology 71, 2004, in expanded form. Abstract Spray drift deposition into water bodies may pose environmental and health hazards, and buffer zones have been suggested as a means of mitigating water contamination. Field trials were conducted to determine […]

Drift is… good?
OK, fine. We confess to the shameful use of click-bait in our title. Nevertheless, it’s absolutely true: Drift can be good. The reason this statement is unsettling is because of the lack of context, which is really what this article is about. The majority of sprayer-related information available to ag stakeholders relates to horizontal boom […]

Comparing three brands of water sensitive paper
Introduction Spray coverage describes the degree of contact between spray droplets and the target surface area. This metric can be used to predict the success of an application. One of the easiest methods for visualizing coverage is to use water sensitive paper (WSP), which is a passive, artificial collector that turns from yellow to blue […]

We Need Better Drift Control Technologies
Sprayer manufacturers have all but offloaded the entire responsibility for drift management to the sprayer nozzle. It’s asking too much. Sprayers have changed a lot over the past 25 years. They have become larger, with more tank capacity, boom width, and, if self-propelled, horsepower. They are more comfortable and ergonomic, with more sophisticated swath control […]

The Label Summary Sheet Proposal

From the perspective of the spray applicator, the information needed most often can be difficult to locate, anachronistic, contradictory, subjective or even missing from the label altogether. To truly encourage an applicator to read and follow the label we need a consistent, concise and clear format […]
