Herbicide researchers pick new fights

Different modes of action may overcome a lull in herbicide discovery

Herbicide development has slowed in recent years, but innovative research methods could soon drive significant progress in the field. For decades, the pace of discovery of new modes of action — that is, how a herbicide interferes with the plant’s normal functions — was robust. From the 1950s through the 1980s, an average of one […] Read more


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

Some biostimulant products are meant to help see crops through environmental stressors such as unusual cold or heat.

Biologicals aren’t the silver bullet

The products can be complements, not replacements, for other inputs

Glacier FarmMedia — Biological products have been touted as replacements for synthetic chemistry and fertilizer in crop production, but that may be a false promise. According to one pitch, if farmers add biological X to the soil, they can cut nitrogen rates by 15 pounds per acre. According to another, biological Y can control a […] Read more

Let’s look at the facts on pesticides

Practical Research: Chemicals found in nature aren’t intrinsically safer than the man-made options

The May 2024 edition of Consumer Reports, published by a well-regarded U.S. not-for-profit independent organization, examined “Produce Without Pesticides.” The article carried a lead statement that some 20 per cent of the 59 fruits and vegetables in its ratings posed a high risk for pesticides. It also made the statement that some of our favourite […] Read more

Your fearless columnist tosses the cell for electrical conductivity (EC) measurement into the Montreal River at Saskatchewan Highway 2 in July 2005. Results are recorded in a notebook and all is carried in a briefcase. I have notebooks like that all the way back to 1982. At this location, water EC is 260 uS/cm. In the north, water is mostly low EC; the standard for comparison is the South Saskatchewan River system that runs through Saskatoon, with an EC of about 450 uS/cm at 25 C.

Water chemistry: a Coles Notes version

Soils & Crops: Conductivity and hardness of water samples show what you can use it for

First of all: readers who have Henry’s Handbook of Soil and Water can check out pages 124-125 for a detailed discussion of water chemistry, complete with calculations. Water is considered to be the universal solvent because it is capable of dissolving more substances than any other liquid. Therefore, one of the first things we might […] Read more

Spraying facts, fallacies and forethought

Experts share tips on what you need to know before you spray

To spray or not to spray? That is the question many farmers will be asking themselves in the coming weeks. While it’s still too early to say what pest and disease forecasts will look like this season, it’s never too soon to start thinking about temperature and other factors that can help to determine the […] Read more
