Boom stability, boom height and travel speed are critical to uniform herbicide application and curbing variability in spray coverage.

Tackling herbicide resistance with smarter spraying

Tom Wolf from Sprayers101.com shares insights on how spraying techniques and technologies can help farmers stay ahead of resistance

Justin Prickel demonstrates the WeedSeeker 2 system’s ability to detect a weed during Agco’s 2024 Tech Day event near Salina, Kansas in June. PTx Trimble is now part of a joint venture between Trimble and Agco.

WeedSeeker 2 offers spot-spraying retrofit for existing sprayers

A drone lifts off at Canada’s Outdoor Farm Show at Woodstock, Ont., this September. There are no agricultural pesticides currently approved for application with drones, so agronomists must exercise caution when asked for advice on the practice.

Be wary when asked about spraying with drones

Farmers may ask for advice, but answering may get you in hot water

It could happen anytime. As drone fever sweeps across Western Canada, a farmer is eventually going to ask an agrologist or crop advisor to teach them how to spray pesticides with drones. What do you do? Igor de Albuquerque advises extreme caution. “If the product in question does not include drone usage on its label, […] Read more


The spray window for fusarium head blight in wheat may only be a few days, so timing is critical.

Four tips for FHB spray applications in wheat

To prevent outbreaks consider spray preparation, double nozzles, coarser sprays and lower booms

Fusarium head blight (FHB) is one of the most destructive wheat diseases in Western Canada, affecting the yield, grade and end-use quality of infected crops. Fungicides can be very effective in preventing FHB outbreaks, as long as they’re applied on time and sprayed the right way. Tom Wolf, a sprayer expert and scientist at Agrimetrix […] Read more
