Herbicide resistant weeds aren’t a novelty anymore — now they’re just the norm

While herbicide resistance isn’t a new problem, it is a growing one. Today 80 countries report herbicide-resistant weeds, says a researcher. And Canada is near the top of that list. Dr. Ian Heap heads the international survey on herbicide-resistant weeds, and reported those findings at the Herbicide Resistance Summit in Saskatoon this March. “North America […] Read more

PHOTOS: Small-scale sprayers offer targeted weed killing

Today’s high-clearance farm sprayers come equipped with boom widths of 100 feet or more, which makes getting them into sharp corners or tight places pretty difficult. And with some precision ag data collection systems now able to pinpoint small problem weed areas in a field, spraying them with very wide booms may mean wasting product. […] Read more


Farmers check out pea plots during the Western Applied Research Corporation’s annual field day at Scott, Sask. Weed control is a perennial problem for pea producers.

Managing Group-2 resistant weeds in pulse crops across Western Canada

Cleavers, mustard, kochia and sow thistle are among the weeds getting harder 
to control, but there are methods, starting with good agronomy

Group 2 resistance is something that is really a big problem across Western Canada,” says Dr. Chris Willenborg, a researcher at the University of Saskatchewan’s plant sciences department. Willenborg has worked on several research projects that inform weed resistance in pulses. The bad news is that resistance is spreading. And the more farmers rely solely […] Read more

Dow enlists a new stacked trait

Dow is registering Enlist seeds, corn and soybeans tolerant to glyphosate and 2,4-D

The biggest new development on the horizon for Dow Seeds corn and soybeans is the Enlist weed control system. Enlist corn and soybean seeds will be tolerant to both glyphosate (Group 9) and 2,4-D (Group 2). “We’ll be adding the additional tolerance of 2,4-D to the glyphosate trait that’s already in corn and soybeans,” says […] Read more

Use a true desiccant for best dry-down

A big part of getting high quality peas and lentils in the bin is using a “true” desiccant that gives you a fast, even dry down. How I define a “true” desiccant? Simple. A true desiccant is not systemic and works by actively bursting the live cell of the plant on contact, thus releasing moisture. […] Read more

Crop Diagnostic School: Know your target weed issues... and your problem weeds of the past

To help keep herbicide-resistant weeds at bay, some older soil-applied products are rejoining the fight. At the 2015 Crop Diagnostic School, Jeanette Gaultier, pesticide use specialist with Manitoba Agriculture, Food and Rural Development, talks about which herbicide-resistant weeds producers should watch for and what they need to consider before choosing a herbicide for their situation.

Hard water hampers weed control

To get the most from the herbicides you’re spraying in your field, check your water quality first

A North Dakota State University extension specialist says the performance of some herbicides can be adversely affected by using hard water to prepare spray mixtures. According to Richard Zollinger, there are a variety of water quality issues that can impact herbicide efficacy, including the presence of clay, silt or organic matter in the water. But […] Read more

Herbicide-resistant weeds changing farm practices

Resistant weeds are driving U.S. farmers to actions like manual weeding

Arkansas has been ground zero for herbicide-resistant weeds. For instance, the state is second only to Australia in the amount of herbicide-resistant ryegrass in wheat. “We’re actually running out of herbicides, making it difficult for us to even grow wheat in Arkansas, because of the levels of resistance that we have,” said Dr. Bob Scott.

Chemical safety on the farm

You use them so often they may not even seem to be all that dangerous
 anymore. But make sure you know just what you’re dealing with

Every year farmers and farm workers come in contact with a wide variety of chemicals. Often they’re used every season and farmers can become familiar with them, even a bit complacent about the dangers they pose. Each chemical will have an information sheet and information tag. All chemicals and medications have Material Safety Data Sheets […] Read more
