In almost all agronomic practices, timing is key. There are certain, and often small, windows of opportunity for getting a task done without losing yield potential or product quality. Weed specialists talk about early weed removal, pathologists talk about symptom monitoring, and entomologists remind us of economic thresholds. Acting at the right time is fundamental. […]
It happened three times this spring. As is often the case, I was contacted by growers who wanted help with herbicide application. In most of these calls, the discussion revolves around the proper choice of nozzles for a specific task, perhaps some questions on spray pressure, water volume and travel speed. But these three were […]

This research was performed with Dennis Van Dyk, OMAFRA Vegetable Crop Specialist. In 2018, MS Gregson introduced a line of electrostatic sprayers (the Ecostatik) in Canada. While electrostatic technology has been used in agriculture since the 1980’s, this is the first time ground rigs have been so readily available to Ontario (possibly Canadian) growers. The 3-point hitch […]
Dear reader: This article is intended to provide basic information on how electrostatic sprayers work in an agricultural setting. The author does not sell or manufacture sprayers. If your interest is related to spraying disinfectant in private or commercial settings, please contact retailers or manufacturers of electrostatic sprayers. Electrostatic nozzles have been tested in agriculture since […]
Spray adjuvants are tank mix additives that either physically or chemically influence the efficacy, consistency or safety of pesticides. For example, adjuvants can improve the handling characteristics of a spray solution (e.g. water conditioners, de-foamers, emulsifiers). They can improve uptake into a target plant and/or improve the amount of contact between spray droplet and target […]
