Bayer puts Roundup future claims settlement on hold

Judge questions proposal for third-party scientists to rule on chemical's carcinogenicity

The German company said that lawyers representing those preparing a class action had withdrawn a request for

Weather conditions that can volatilize dicamba herbicide

Avoid applying all herbicides during temperature inversions too

In addition to drift caused by wind the herbicide dicamba can end up off target due to volatilization, also referred to as vapour drift, and temperature inversions. Last week’s stories on dicamba (see ‘Related Articles’ below) prompted a reader to ask about the weather conditions for both. The University Minnesota explains it on its website

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.

Precautions to take when applying dicamba

The best way to avoid dicamba drift is to follow label directions. Although dicamba can be applied to Xtend soybeans from pre-emergence to early flowering, applying pre-emergence has advantages. One is if your crop isn’t up, your neighbour’s might not be either and can’t be damaged by drift. “Dicamba provides residual control for a short

Breaking down the recirculating sprayer boom

Non-profit Sprayers 101 demonstrates the concept and benefits of a recirculating sprayer system

Looking at the back of a modern sprayer the pile of hoses and valves in a traditional plumbing system can seem complicated, and even more so when you start to look at recirculating sprayer booms. Hoping to mitigate that confusion, Dr. Tom Wolf and Dr. Jason Deveau have “Everything you never wanted to know about

Spring weeds rise up well ahead of seeding efforts

Weed forecasts have farmers expecting to reap the consequences of last year’s lack of field work

Farmers are gearing up for spring seeding, but the weeds have already made it to the field. Manitoba’s provincial weed specialist, Tammy Jones, says producers are already starting from behind on weed control this year, thanks in large part to harvest conditions last fall. Why it matters: Seeding is stressful enough as is, but farmers
