Glyphosate-resistant weed marching north

A weed that has devastated cotton and soybean crops in the southern U.S. has crept into South Dakota, 500 kilometres from the Canadian border.
North Dakota State University weed scientists reported this summer that Palmer amaranth, which can grow to four metres in height and can have a stem the diameter of a baseball bat, is[...]

Weed expert frustrated by farmer inaction

Richard Zollinger is done talking to North Dakota farmers about herbicide resistance.
Zollinger, a North Dakota State University weed specialist, said glypho-sate resistant waterhemp, kochia, horseweed and common ragweed all live in the state, but most growers ignore the issue.
“We (weed scientists) have been preaching weed resistance, just like they have in Canada, since the mid-90s,”[...]

Farmers must change practices before control options run out

Humans are creatures of habit. We find comfort in familiarity.
We are also creatures who don’t always pay enough attention to the consequences of our decisions, preferring immediate gratification over what is in our best interests over the longer term.

World in brief


Russia’s retaliation Russian food embargo to cost Europe billions BRUSSELS, Belgium (Reuters) — Russia’s ban on Western and European Union food imports, part of its response to EU sanctions imposed over the Ukraine crisis, could cost the European Union $6.6 billion US a year, according to an internal EU document. Russia, which is the EU’s[...]

Weed scientist predicts demise of glyphosate

WASHINGTON, D.C. — Stephen Powles is not optimistic about the future of glyphosate in Canada and the U.S. Powles, a farmer and weed scientist at the University of Western Australia, said the herbicide might have a shorter lifespan than farmers' imagine. "I'm going to make here a very bold prediction: glyphosate will be driven to[...]

Glyphosate as desiccant less than ideal: experts

Applying glyphosate before harvest isn’t a significant concern when it comes to herbicide resistance, says an Agriculture Canada weed expert.
“It does add some selection pressure, but a lot of the selection has (already) taken place. You’re mostly just drying down the crop,” said Neil Harker, Agriculture Canada weed scientist in Lacombe, Alta. 
“What’s left when[...]

Crop report

Saskatchewan SOUTH Less then 10 percent of crops have been swathed or straight-cut, and less than five percent combined. Harvest progress varies widely between southwest and southeast. Farmers have started combining winter wheat, lentils, field peas and fall rye, and swathing has begun for canola. Many crops are about a week behind normal development for[...]

80 percent mature heads ideal time for pre-harvest glyphosate

I had an interesting question from a grower this week. The question was “What is the operation that if I screw up, costs me the most money?” Basically, he was asking for an evaluation of his practices and suggestions on how he could improve. This is different from most questions from farmers. Most want to[...]

Manitoba crop report for Aug. 18

SOUTHWEST Welcomed precipitation varied from 10 to 30 millimetres. Spring wheat, oat and barley crops are quickly maturing and within two weeks of swathing or preharvest glyphosate application. Some areas have begun winter wheat harvest. Quality and yields are reported poor. Fusarium damaged kernel levels range from five to 20 percent and test weight is[...]

Farmers forced to become warehousing titans

Producers are growing weary over the steady stream of buy-it-early advice. All the stories of impending shortages are fuelling skepticism. 
This spring, analysts sounded more certain than ever that fertilizer availability would be a big problem. The same logistical problems curtailing grain movement were expected to spill over into fertilizer delivery. 
Scribes including this one,[...]

Crop report - August 7, 2014

Manitoba SOUTHWEST Crops continue to improve as a result of mild and drier weather, but long-term yields are expected to be average. Precipitation was five to 15 millimetres, while temperatures were at ideal levels for crop development. The drier, less humid conditions are helping keep disease levels for most crops at low to moderate levels.[...]

Farmers to get controversial chemical next year

CARMAN, Man. — Jeff Loessin made an observation that was impossible to miss while squatting down to examine soybean plants in a plot trial. One row of beans was perfectly clean and the next row was inundated with volunteer canola. Loessin, a portfolio marketing leader for crop protection with Dow Agrosciences, said the weed-filled row[...]

Identification is first step when keeping out new weeds

RIDGETOWN, Ont. — Producers are encouraged to hone up on their weed identification skills, and with good reason. “If you misidentify something, you may not be able to control it, and some of the weeds are a huge problem outside of the Ontario because of herbicide resistance,” Dave Bilyea, a research technician at the University[...]

U.S. farmers fighting explosion of 'superweeds'

(Reuters) — Farmers in important crop-growing states should consider the environmentally unfriendly practice of deeply tilling fields to fight a growing problem with invasive "superweeds" that resist herbicides and choke crop yields, agricultural experts said this week. Resistance to glyphosate, the main ingredient in widely used Roundup herbicide, has reached the point that row crop[...]

Weed of the Week: dock

Whether they call it curly dock, narrow-leaved dock, sour dock or yellow dock, for farmers it is usually a sign of water, a sprayer miss, or both. Standing above most crops, dock is a perennial with the ability to produce high numbers of seeds. Its single, sometimes forked, large taproot has allowed it to flourish[...]
