Low, high or in the middle, soil pH affects your farm

Acidic or alkaline soils can have a big effect on soil nutrition, but while farmers with acidic soil 
can turn to lime, fixing alkaline soils may be more of a challenge

Alkaline soils are a common problem in Manitoba, but farmers may not have an easy fix. Amir Farooq, crop specialist with Manitoba Agriculture and one of the speakers at a soil fertility update in Brandon Jan. 30-31, argued that high pH soils would need a prohibitively expensive amount of elemental sulphur to lower levels. The

Soybeans damaged by dicamba. The Arkansas State Plant Board wants to ban in-crop dicamba use from April 15 to October 31 following almost 1,000 complaints about dicamba drift damaging nearby crops. The proposal needs approval from the Executive Subcommittee of the Arkansas Legislative Council.

Arkansas moving closer to in-crop dicamba restrictions

Its plant board wants an April 15 to Oct. 31 ban to prevent injury to crops from drift

Arkansas farmers might not be allowed to apply dicamba in annual crops during the 2018 growing season. A regulatory change prohibiting dicamba applications between April 15 and Oct. 31, was approved by the Arkansas State Plant Board, Arkansas’ Agriculture Department said in a news release Sept. 21.

Broadcasting nitrogen in fall least efficient approach

It’s also the least environmentally friendly

Broadcasting in fall is the quickest and easiest way to apply nitrogen — and the least efficient. So why, anecdotally at least, does the practice seem to be on the increase? Bigger farms and a shortage of labour could be part of it. Moreover, nobody knows when poor weather will shut down field operations. And

Quebec researchers say a new treatment can remove atrazine from 
surface water.

Cleaning up chemicals

Atrazine is the most common weed killer found in Quebec surface water, which prompted the research

A group of Quebec researchers, at that province’s Institut National De La Recherche Scientifique, say they’ve identified an effective way to remove the pesticide atrazine from surface water. Atrazine, widely used as a weed killer, is known to have harmful effects on aquatic wildlife and presents a risk to human health by altering the action

The decision to apply glyphosate or a true desiccant ahead of harvesting soybeans will depend on the weeds being controlled.

Pre-harvest glyphosate on soybeans?

Yes, no or maybe — it really all depends on the weeds

Whether to apply glyphosate or a true desiccant before harvesting soybeans depends on the weeds in the crop, Manitoba Agriculture weed specialist Jeanette Gaultier, said Sept. 20 during the Crop Talk Westman webinar. “If your issues are winter annuals and perennials I would definitely go in with glyphosate because obviously it’s a systemic — it’s


Health Canada had no herbicide drift complaints from Manitoba

That includes the herbicide dicamba, which has triggered many drift complaints in the U.S.

Health Canada has not received any herbicide drift complaints in Manitoba this season, including related to dicamba, André Gagnon, a media relations officer serving Health Canada and the Public Health Agency of Canada, said in an email Sept. 12. That contrasts sharply with the United States where the University of Missouri says 3.1 million acres

The latest estimates are that as much as 50 per cent of the crop area in Western Canada could be affected by Group 1- and/or Group 2-resistant wild oats.

Ag in Motion: Managing herbicide resistance

Diversity is defined in the dictionary as “the condition of having or being composed of differing elements.” In weed control, diversity means using multiple strategies, or an integrated weed management approach. For herbicides, this means using all of the modes of action available to reduce the risk of weed resistance. This may be obvious, but

Alloway straw cutter makes combines run smoother

Our History: August 1965

The Alloway straw cutter advertised in our August 5, 1965 issue was said to be simple to install, and due to the drum design and weight, would actually make the combine run smoother. The issue contained several photos from the Threshermen’s Reunion at Austin. Encouraged by another excellent turnout, the directors were considering expansion and


Canola growers urged to be smart: don’t use Clever (quinclorac) until importers set MRLs

Those who have sprayed canola with the herbicide need to inform buyers at delivery time

The Canola Council of Canada is warning growers that using the newly released herbicide called Clever on their canola crops this year might not be a smart idea. That’s because Japan, one of Canada’s biggest canola customers, has not yet established a maximum residue level (MRL) for the active ingredient, quinclorac, which means all grain

Both the treated and untreated soybeans were planted May 25 at Oakville, Man. The untreated plot photographed June 23 is weedy while the plot sprayed pre-emergence with a glyphosate and dicamba tank mix was virtually weed free thanks in part to dicamba’s residual weed control. The treated soybeans had not received a second glyphosate treatment yet.

Tips on applying dicamba/glyphosate tank mix on Xtend soybeans

The implications of residual control, plus mitigating drift and sprayer cleanout

Roundup Ready Xtend soybeans, which can be safely sprayed with glyphosate and dicamba, offer many advantages, but there are several things to keep in mind when applying dicamba. Dicamba provides residual weed control — 14 days or even longer under certain conditions, Allan Froese, Monsanto’s technology development representative, said during a field day June 23.
