Feds to change pesticide oversight

The federal government is adopting a new way to manage pesticides, which seems to give a larger role to Environment and Climate Change Canada. On June 20, the government announced the next steps toward a “sustainable approach to pesticides management.” In the past, Health Canada’s Pest Management Regulatory Agency was responsible for pesticide regulation in […] Read more

Wind can be an applicator’s friend, says expert

A windy day can provide ‘directional certainty,’ but farmers should avoid spraying in extreme conditions

Wind, wind, wind: it keeps the bugs away, but if you’re a busy farmer with thousands of acres of crop to spray, it can be a royal pain in the neck. Applying expensive and potentially damaging chemicals in windy conditions is not an ideal scenario, says Tom Wolf, a chemical application expert and president of […] Read more

Roga Drone will use Kray Technonogy’s eight-rotor, hybrid UAV to spray from a 16.5 foot wide boom. The company is planning to cover 40 to 50 acres per hour, depending on label rates of the pesticide being applied.  |  Don Campbell photo

The drones are coming to spray your crops

CORRECTION: This story originally said Don Campbell revived approval from Transport Canada to apply crop protection products with a drone. However, Transport Canada only gave Campbell a special approval to emit fluids from a drone. The Pest Management Regulatory Agency is responsible for the regulation of pest control products in Canada.   Roga Drone is […] Read more


Spray technology

Three years deposition experience Robert Brunel has often used a deposition agent in his Apache high clearance sprayer in the past three years. WinField’s InterLock has cost him $1 to $3 per acre, depending on wind, the crop and the product he’s spraying. He said it’s a small price to pay for the benefit he […] Read more

Spraying time is all about acres, not reloading. Techniques to reduce filling time allow farmers to spend more hours in the cab. A producer near Kindersley, Sask., applies a pre-harvest application of glyphosate in the first week of September.  |   Robin Booker photo

Less time spent filling means more time spent spraying

Cutting sprayer fill times in half would significantly improve farmers’ bottom lines, says a spraying systems engineer. Syngenta researcher Doug Baumann has developed and proofed a mathematical model showing how a producer can fill a 1,200 gallon sprayer in six to eight minutes. He said optimizing fill time is the easiest way for farmers to […] Read more


Darren Robinson talks about plots in which herbicide drift events were simulated. With an exposure rate just five per cent of the label rate, damage can be significant depending on the crop.

Ontario growers failing to prevent herbicide drift

RIDGETOWN, Ont. — Herbicide drift can be managed, but the risk may be too great even when the best protocols are in place. “If there are sensitive crops around you, you can make the decision not to apply a chemical,” said Adam Pfeffer, a development representative with Monsanto. “If a plant is sensitive to a […] Read more

Tom Wolf uses a hand-held boom to demonstrate that dual tip nozzles have serious coverage problems when spraying in windy conditions.  He uses paper test strips at a cost of about $1 each to check the pattern going both directions.  |  Ron Lyseng photo

Effective spraying starts at the top

Dual tip nozzles may be great for fusarium, but planning and timing are more critical than the technology

PORTAGE LA PRAIRIE, Man. — Only 15 percent of the efficacy of a crop protection package depends on application technology and the spray operation itself. Thinking accounts for the other 85 percent. In fact, technology and application rank a distant third place on the list of three factors that affect the success of a crop […] Read more

Tom Wolf says producers must consider efficiency of spray nozzles as well as proposed regulations on application methods.  |  File photo

Correct nozzle use moves to political radar

Using the right nozzle for the right product at the right water rate could some day become a legal requirement. Tom Wolf of Agrimetrix in Saskatoon says farmers need to consider their application methods as carefully as they do their rates of product. “Legislation is in all of our futures,” he told a farm meeting […] Read more


Cleaning up after spraying is not another job, it is part of the process of spraying. It is also an opportunity to find plugged nozzles and leaks.

Sprayer cleanup not to be ignored

Chemicals can build up in the sprayer and cause problems for later operations if they are not properly cleaned out

A spray day doesn’t end when the farmer parks the rig. Producers who use Group 2 products that are formulated as a dry fine ground powder have one more important task when they park the sprayer: cleanup. The issue is compounded if they mix Group 2 dry products with other products that have an oily […] Read more

Better efficacy with less water

A spray plane equipped with rotary fan atomizer nozzles can reduce drift and put more product on a crop while dramatically reducing water volume. Until recently, aerial applicators with standard nozzles typically put down three to five gallons of water per acre. However, applicators who equip their planes with Davidon Hi-Tek rotary fan atomizer nozzles […] Read more
