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 […]

Methods for Determining Nozzle Flow Rate

Calibration should be a regular practice for every operation that uses a sprayer. Part of that process is confirming that each nozzle is operating within the manufacturer’s specifications. This is a must for researchers that adhere to Good Laboratory Practices and for custom operators that sell their services. But we didn’t just fall off the […]

Beluga Drop Hoses in Corn – Utility and Return on Investment

In 2019 we evaluated the spray coverage from nine application methods on corn silks. The results showed that a directed application from drop hoses (aka drop pipes, drop legs) suspended in between the rows gave significantly higher deposits. If you’d like some context and history, the article can be found here. The results led us […]

Angled Spray Nozzles in Wheat

When T3 wheat rears its head, the first rainy day brings questions about spray angles. Let’s begin with a graphic that illustrates how angled sprays cover a vertical target like a wheat head. Assuming moderate wind and sufficiently large droplets, this is a simplified depiction of what we would expect to see. But is this […]

Herbicides in Asparagus – A homegrown solution

In 2016, an asparagus grower in southern Ontario picked up a used De Cloet Hi-Boy originally used to spray tobacco. His vision was to create a three-row herbicide sprayer for asparagus and we were invited to participate. His concept was to design shrouds that would contain the herbicide, but not snag the asparagus or drag […]
