Stacked tolerance traits taking on herbicide-resistant weeds
Next-generation herbicide stacks are on their way to help fight not only weed resistance, but more weed species too
Reading Time: 8 minutes A number of next-generation herbicide-tolerant crops are in the pipeline for soybean and canola growers, but the offerings won’t include any magic bullets. Instead, what we’re likely to see first are more stacked tolerance traits. It’s because life science companies have their own kind of stacking to deal with. Their new traits are lined up, […] Read more
Herbicide-resistant weeds are our biggest threat
There’s no reason why the West must become an Arkansas-style nightmare because of weed resistance, but we may be heading there anyway

Pest Patrol: Weed control update on vetch
Can I do anything to get rid of vetch before seeding soybeans?
Reading Time: < 1 minute In my last column, I discussed my optimism for vetch control in soybeans using a few different pre-plant burn-down herbicides. Specifically, I had been impressed by some preliminary results when either flumioxazin (found in Valtera, Step-Up, Fierce and Guardian Plus) or saflufenacil (found in Eragon, Integrity and Optill) was mixed with glyphosate and the adjuvant Merge.
