Spot spraying advancements include building algorithms

Advanced spraying systems have benefits, but they also have costs that must be taken into consideration


Spot spraying isn’t a new idea, and the equipment capable of performing selective applications has been around for decades. However, the technology that supports this approach is advancing. Tom Wolf, an application specialist with Agrimetrix Research & Training and Sprayers101, recently shared some of the new research, technology developments, and application techniques during the Western […] Read more

Crop Production Show 2025: Spray drone research continues

Tom Wolf, a research specialist at Agrimetrix, shared some of the spray drone research he and others in the subject area have done at the Nufarm Information Theatre during the Western Canadian Crop Production Show yesterday. While the use of spray drones for chemical application is still illegal in Canada, research on how to use […] Read more

Legal drone spraying takes step closer to reality

CFIA says the work that is ongoing to satisfy federal regulatory authorities is moving faster than previously anticipated

The ray of hope might be dim right now, but farmers wanting to legally spray pesticides on their crops using drones may be seeing the first hint of light at the end of the tunnel. Ross Breckels, a senior scientific evaluator with Health Canada’s Pest Management Regulatory Agency (PMRA), said the process of getting common […] Read more

Innovation is critical to the future of agriculture, especially if there’s more volatile weather on the horizon, as we’ve been told to expect. Farmers will need as many tools as possible to pivot quickly and adapt on the fly. | Screencap via vimeo.com/GuardianAg

Canada’s regulatory model slows innovation on the farm

Glacier FarmMedia – In early July, Manitoba Pork Council general manager Cam Dahl argued in an opinion piece that Canada’s product approvals process puts producers at a competitive disadvantage. “Farmers in competing countries like the U.S. have rapid access to new products and technologies, while the slow pace of regulatory approval in Canada can block […] Read more

Should farmers use drones to spray?

Producers are eager to adopt DIY aerial spraying, but a slow, careful approach if warranted, says sprayer expert

A number of farmers across Western Canada are using unmanned drones to spray crop protection products, and they’re doing it undeterred by a lack of regulatory approval, say ag drone experts. Markus Weber, president of Alberta-based LandView Drones, sells drones for agricultural applications, including crop spraying. Up until a few years ago, farmers were primarily […] Read more

Last fall bleaching, black splotches and pockmarks appeared on vegetation in gardens within Speers, Sask. The Saskatchewan Ministry of Agriculture found that the damage was connected to a spray plane that was applying herbicides to crops near Speers in mid-August.  |  Photo submitted by Speers resident

Pesticide damage seen in small-town Saskatchewan

WINNIPEG – In mid-August last year, people in Speers, Sask., noticed a spray plane flying over the town and nearby for three consecutive days. The plane was applying pesticide to fields around Speers, a community of 70 people about 100 kilometres northwest of Saskatoon. The residents didn’t think much about it because spray planes are […] Read more

Spraying in dry times can be tricky

Heat waves and dry weather added to the headaches faced by canola producers during spraying season. “The main concern with the heat is just the evaporation of water from the droplets, and that causes two main problems,” said Tom Wolf, owner of Agrimetrics Research and Training based in Saskatoon. Other stories in the 2023 Canola […] Read more

Slow down, up the volume, reduce the pressure

A spraying specialist weighs in on how producers can achieve effective deep canopy coverage while applying fungicides

In Agrimetrix research conducted in chickpeas and field peas, water volume was the most important factor associated with good canopy penetration.
