There are signs indicating glyphosate-resistant kochia is still rare in Manitoba, but farmers need to be vigilant to keep it that way.

Signs indicate glyphosate-resistant kochia still relatively rare in Manitoba

Farmers are being asked to submit suspected cases for testing and encouraged to remain vigilant

Glyphosate-resistant kochia still appears to be relatively rare in Manitoba, but that’s no reason for farmers to become complacent, the provincial government’s weed specialist says. In fact, the situation calls for more vigilance, rather than less, Jeanette Gaultier, weed specialist with Manitoba Agriculture, Food and Rural Development (MAFRD) said. Glyphosate-resistant kochia was confirmed in just

Fall a good time for winter annual, perennial weed control

Whether you apply a desiccant or glyphosate depends on the weed and your harvest plans

The swather and the combine are good places from which to spot weed problems and autumn can be a good time to control winter annual and perennial weeds, says Jeanette Gaultier, weed specialist with Manitoba Agriculture, Food and Rural Development. Pre-harvest control hinges on the type and stage of weeds and harvest goals. If a

Crop Diagnostic School: Know your target weed issues... and weeds that have caused you trouble in 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.

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

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.

Monsanto’s new glyphosate- and dicamba-tolerant Roundup Ready Xtend soybeans offer improved weed control, including some residual control, potentially higher yields and can help slow the onset of glyphosate-resistant weeds, says Dekalb’s Bruce Murray. Seed is being multiplied now for a commercial launch in 2016 pending their acceptance in China.

Monsanto rolls out ‘Xtend’ glyphosate-dicamba-tolerant soybeans

Manitoba farmers could be planting these dual-stacked 
GM soybeans as early as next spring

Monsanto’s new glyphosate- and dicamba-tolerant “Xtend” soybeans will give farmers better weed control, higher yields and delay the onset of glyphosate-resistant weeds, company officials told agronomists and reporters here June 23. And if China approves their import, North American farmers, including in Manitoba, will be planting Xtend soybeans next spring, said Pat Comte, Monsanto’s strategic

VIDEO: Roundup Ready Xtend crop system for soybeans, avoiding spray drift

Monsanto’s new Roundup Ready Xtend soybeans are glyphosate and dicamba tolerant. Here are some tips on avoiding dicamba drift

Manitoba Co-operator reporter Allan Dawson spoke with DEKALB agronomist Bruce Murray June 23 about Monsanto’s new Roundup Ready Xtend soybeans. Monsanto’s technical development representative Allan Froese also demonstrated how different nozzles affect spray droplet size.

Manitoba overhauling Noxious Weeds Act

Noxious weeds will be listed in three tiers with control action 
based on the threat to agriculture and natural areas

The Manitoba government is overhauling one of the oldest laws on its books — the Noxious Weeds Act — to bring it into line with current weed threats in the province. If passed, Bill 32, the Noxious Weeds Amendment Act, will put into statute much of what is already common practice — controlling weeds commiserate

Tank mixing weed killers helps delay herbicide-resistant weeds

But don’t forget to rotate crops, including fall seeded and perennials, 
advises AAFC’s Hugh Beckie

Tank mixing two herbicides with different modes of action targeting the same weed is a good way to delay the development of herbicide-resistent weeds, a study by weed scientists at the University of Illinois and United States Department of Agriculture concludes. “We don’t say that mixing is the end-all solution,” study co-author Pat Tranel of
