Avoiding residues is now two clicks away

Producers can ensure the chemical sprayed on their canola or pulses won’t leave unacceptable residues by adhering to the pre-harvest interval — or PHI — found on the product’s label. Often referred to as the “spray to swath” interval, the PHI is the number of days that must pass between spraying pesticides or desiccants and […] Read more

Don’t forget about residue limits before you harvest

If you’re still considering pre-harvest weed control or a desiccation product, don’t forget about maximum residue limits. “Producers need to ensure they adhere to the pre-harvest interval which is the time from applying a product until it is either swathed or combined,” said Nevin Rosaasen, policy and program specialist with Alberta Pulse. Detailed information on […] Read more


These Manitoba Department of Agriculture photos show that weeds are more obvious when looking 
down at a wheat crop (r) than looking at it sideways.

It’s the time of year when crop scouting pays big dividends

Weed escapes, herbicide resistance, disease, and pests can all be assessed after spraying, says expert

Spray, then scout, says provincial crop specialist Mark Cutts. “It is very important to recognize that scouting after a herbicide application is vital to weed control, said Cutts. “In the majority of cases, producers will find that the chemicals have worked. However, in certain situations, field scouting may show the weeds weren’t properly controlled. Producers […] Read more

Wet weather last August has increased the odds of pea leaf weevil infestation this year.

Another hangover from last year’s dismal weather

Pea leaf weevil have been spreading north and last summer’s wet conditions will give them a boost this year

Research shows that treating pea seed with a systemic insecticide product is the most effective control measure to prevent pea leaf weevil damage. Legume crops such as field peas and fababeans produce most of the nitrogen they need, but pea leaf weevils “greatly compromise” that process, said provincial crop specialist Neil Whatley. The pest showed […] Read more


Did your spraying do the trick?

If weeds survived, you need to figure out what went wrong so you can avoid a repeat

Field scouting after herbicide application can lead to more successful crop production. “In the majority of cases, producers will find that the chemicals have done their job” said provincial crop specialist Mark Cutt. “However, in certain situations, field scouting may show the weeds weren’t properly controlled.” If so, figure out what went wrong. “A difference […] Read more

Dew makes mornings the worst time to spray, Farming Smarter researchers have found.


Farmers, hit that snooze button — spraying later is your best bet

For pre-seed burn-down and broadleaf weed control, it’s better to 
spray during the day rather than early morning or nighttime

A plant in the morning dew is a little like a man stepping out of a shower — wet and cold, and that much colder because it’s wet. “The phase change between a liquid and a gas sucks heat energy out of the plant. That practice will actually hurt the plant,” said Ken Coles, general […] Read more


Looking to improve spray coverage? Try pulse width modulation

Pulse width modulation maintains spray pressure and droplet size at different travel speeds

Nozzle guy’ Tom Wolf is often asked about ways to improve spray coverage. But as he says — borrowing a turn of phrase from Paul Simon — “there must be 50 ways to improve your coverage.” And one of them is through pulse width modulation — a relatively new technology that’s “on the move.” “I […] Read more

Save your spray: Crop disease risk drops in drought conditions

But diseases like stripe rust, tan spot, or sclerotinia could be an issue if there’s been decent moisture

This summer’s dry growing conditions have at least one silver lining — lower levels of disease in fields. “In those areas that have had very little rainfall this summer, you’re probably looking at limited development of diseases,” federal research scientist Kelly Turkington said in a July 6 interview. “Of more concern would simply be poor […] Read more


Going ‘off label’ is a bad idea all around when it comes to pesticides

You can not only be fined, but also put your customers, the environment and your business at risk


The practice of ‘off-label’ spraying is not only illegal and can result in severe fines, but can also be very dangerous for your clients, your livelihood, and the environment, says a provincial commercial horticulture specialist. “Horticultural chemicals and pesticides often have the dubious distinction of being more expensive than their field crop cousins. In order […] Read more

“We lost money with most advanced agronomic practices. Most things actually resulted in a net economic loss.”


Fungicide application offers best bang for your buck — in the right conditions

Expert says fungicides paid off big for wheat in wet conditions, 
but plant growth regulators and extra nitrogen weren’t worth the cost

You know the old saying: In order to make money, you’ve got to spend money. But spend it wisely, says an Alberta Agriculture research scientist. “There’s a lot of different agronomic practices out there that you can spend money on — but which ones are going to make you money?” Sheri Strydhorst asked attendees at […] Read more
