Crop-Adapted Spraying (CAS) and an Apple Orchard Case Study

The ultimate goal of CAS is to adapt the amount of active ingredient per unit ground area such that the amount of active ingredient per unit target area (usually the leaf area) remains constant for canopies of varying shape and density. When this is achieved with sufficient accuracy, the pesticide efficacy is maintained. These three plants are all significantly different in size. When calibration is appropriate to each plant, the foliar coverage “experienced” for each plant will be the same, in spite of differences in the amount of solution expelled per ground area.

An orchard spraying scenario Here’s a common situation: An orchardist following IPM identifies a pest that poses an economic threat. It’s an annual pest and spraying is really a matter of when, not if. The operation is 150 acres and runs three airblast sprayers; two have a tower and one does not. Multiple varieties are […]

Sprayer Calibration in Belgium

Spring always brings renewed interest in sprayer calibration. This is good, because a well-maintained and calibrated sprayer will protect crops more effectively and efficiently, as well as reduce the potential for off-target drift and point source contamination. Presently, there is no nationally-recognized standard for sprayer calibration in either Canada or the United States. As a result […]
