Evaluating methods for controlling algae in carrier water storage tanks

This work was performed with Mike Cowbrough, OMAFRA Field Crop Weed Specialist. In the early summer months, many field and specialty crop operations collect rainwater (or possibly pump water from holding ponds) into storage tanks for use as a carrier in spray applications. These tanks may be stationary, or they may be part of a […]

Droning On and On – RPAAS Pilot Certification in Canada

In Canada, the use of drones for pesticide application, otherwise known as Remote Piloted Aerial Application Systems (RPAAS), is regulated by two Federal Departments: Transport Canada establishes regulations for safe operation and Health Canada for the registration and conditions of use of pest control products. Drones are already used in Canadian agriculture for crop surveillance […]

Spraying Weather

It’s time to spray and what’s the first thing you do? Check the weather forecast, of course. More often than not, the suitability of the weather is the main factor in the decision to spray. Let’s have a closer look at what each weather component contributes to the decision. Wind: Everyone knows that small droplets […]

How cameras, computers and cake recipes will drive the future of weed recognition

The idea of controlling weeds individually instead of treating the whole field uniformly makes a lot of sense. Why waste herbicides, till soil unnecessarily or use other weed control methods on areas without weeds? Besides reducing unintended environmental impacts, it means cost savings for the farmer, reduced crop stress and the opportunity to concentrate efforts […]

How to Size a Nozzle for Pulse Width Modulation (PWM)

PWM is gaining popularity, and there is an ever-increasing number of first-time users that need to make nozzle selections for their system. We’ve written about it here, here, and here. Recall the PWM replaces spray pressure with Duty Cycle (DC) of a pulsing solenoid as the primary means of controlling nozzle flow. The solenoid shuts […]
