Keeping volunteer canola out of soybeans

Inter-row tillage looks like a promising management tool

By
The average of six per cent canola seed loss during harvest sounds bad enough, but even worse when converted into the number of seeds left to germinate as volunteers the following year. “We’re losing an average of 4,000 to 5,000 seeds per square metre so it doesn’t take a lot of persistence for volunteer canola
The take-home message for soybean growers and agronomists in Manitoba is not to overdo soybean management, says an Ontario soybean specialist.

Soybeans — the ‘kitchen sink’ strategy works, but…

Ontario trials suggest early seeding is the best and cheapest management practice

By
Intensive management can improve soybean yields, but growers should evaluate whether each strategy pencils out, says a soybean specialist with the Ontario Ministry of Agriculture, Food and Rural Affairs. Speaking at the Manitoba Agronomists Conference (MAC) in Winnipeg in December, Horst Bohner described more than a decade of research to evaluate various management strategies to
Data suggests there is most white mould suppression and increased yield when fungicides are applied at the R1 growth stage.

Soybean white mould control options limited

In contrast to canola, there are only four products registered

By
While many Manitoba growers are familiar with the extensive number of fungicides available for dealing with white mould (sclerotinia) in canola, they may not realize that there are a lot fewer options to treat this disease in soybeans. Only four foliar fungicides are registered for control or suppression of white mould on soybeans: Acapela (DuPont),
A study in Manitoba found one adult female of the thirteen-spotted lady beetle ate about 110 English grain aphids in 24 hours.

Engaging natural enemies to fight soybean aphids

The economic threshold for spraying is 
much higher if there is a good population 
of natural enemies

Don’t only count the bad bugs before deciding to spray — count the good ones as well, says Jordan Bannerman of the department of entomology at the University of Manitoba. Bannerman is developing a new decision-making tool that will provide growers a way to predict whether there are enough natural insect enemies present in the

Manitoba Canola Growers Association’s board election results

More than 8,000 ballots were mailed out and just over 1,000 valid ones were counted for a voter turnout of almost 14 per cent

Don’t gamble by not aerating your canola

Uneven maturity means there’s more green seed this year, and that ups the risk of spoilage


By
You can lose a lot of money in a hurry, so watch for potential canola storage problems as fall transitions into early winter, says an Alberta provincial crop specialist. “Canola seed’s high oil content makes it very susceptible to deterioration in storage,” said Neil Whatley. “Safe, long-term canola storage is at or below eight per
A new multigenic clubroot-resistant variety will be a boon for some canola growers, 
but it’s not ‘a saviour,’ says agronomist Dan Orchard.

New variety a milestone in the battle against clubroot

New canola variety has two resistant genes — but clubroot strains are quickly multiplying

By
A new canola variety resistant to multiple strains of clubroot will hit the market in time for spring seeding. But the new variety from Crop Production Services will only be available in limited quantities and a clubroot expert says growers can’t expect it to be “a saviour.” CPS Canada says the variety, Proven Seed PV
Two fields with high-enough levels of clubroot to produce yield-robbing galls on canola roots have been found in the Swan River area by agronomist Ryan Immerkar.

Two fields of canola with clubroot galls found near Swan River

MAFRD’s advice remains the same: soil test for the pest, extend canola 
in the rotation and seed resistant varieties if appropriate

By
Two canola fields in the Swan River Valley had enough clubroot spores this year to produce yield-robbing root galls that characterize the soil-borne disease, says local agronomist Ryan Immerkar, owner of RSI AgriCoaching and New Era Ag Technology. Laboratory testing confirmed the fields have the potentially devastating pest. That brings the number of Manitoba fields

Aquaculture could be big market for camelina

Fish-farming companies are looking 
for a crop-based alternative to fish meal 
from wild stocks

By
A recent discovery in the aquaculture industry may soon make camelina oil a highly sought alternative for fish feed. Currently half of the world’s seafood supply comes from farmed fish, but fish meal from wild stock is still part of the ration, putting a strain on the population. “The proportion of wild fish that is
