“Wind is the barometer for deciding whether it’s a good spray day, and whether that’s right or wrong, it is the deciding factor.” – Tom Wolfe.

Making the most of spray days

Spraying expert Tom Wolfe shares tips for spraying in tough conditions

With another taxing spray season upon Manitoba farmers, the Co-operator is digging into its archives to present you with some previously-published information on navigating these challenges. Waiting for the ideal spray day is about as productive as chasing unicorns, says spray application specialist Tom Wolfe. That’s why learning to deal with less-than-ideal conditions is essential.

Canadian, U.S. farmers diverge on dicamba spray issues

While U.S. farmers have been devastated by dicamba drift, it’s been a non-issue in Canada

Canadian farmers haven’t experienced the same dicamba drift debacle their U.S. neighbours have — but that doesn’t mean they won’t also pay a price for this high-profile failure. Spray expert Tom Wolf says a cooler climate and differences in the way the product is used here have spared Canada the worst immediate effects. The bill


Dicamba spray drift declining in Canada

The climate and how the herbicide is used here both are factors

There haven’t been many dicamba drift complaints in Canada since Monsanto commercialized dicamba-resistant soybeans in 2016. In 2019 Health Canada received just “16 reports of dicamba-related environment incidents in Canada related to drift and over-the-top application of dicamba to soybean,” a Health Canada official wrote in an email June 10.

Terry Buss, Manitoba Agriculture’s farm production extension specialist for pulses, explained dicamba drift on susceptible soybeans last year at the Crop Diagnostic School at Carman, Man.

Dicamba drift not a problem in Manitoba this year

There are many ways to mitigate drift, but using the right spray nozzles is one of the most critical

For the second straight year dicamba drift, which has damaged millions of acres of crops in the United States, hasn’t been much of a problem in Manitoba, officials say. While there’s pressure to further regulate the broadleaf weed killer in the U.S., that’s not the case in Canada. “We’re aren’t seeing an awful lot of

Is it spray drift?

Some in-crop conditions can mimic the same sort of damage caused by drift

Everyone likes gifts, but farmers aren’t likely to welcome extra herbicide drifting in. Manitoba’s spray season has already hit its height, and sprayers have commonly been seen trundling down the provincial highways and grid roads for weeks. But while farmers are already watching for insect damage, stand counts and weed issues, this time of year

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.
