Pest Patrol: Are there any promising new mechanical methods for weed control?

The Harrington seed destructor is one possibility to help avoid spreading weed seed

Reading Time: 2 minutes Ray Harrington, an innovative farmer from Western Australia was struggling with herbicide-resistant weeds, so he took matters into his own hands by using a cage mill from an old mine that he adapted to process the chaff coming out the back of his combine. A team from the University of Western Australia, led by Michael […] Read more

Reading Time: < 1 minute A team from the University of Western Australia conducted a number of on-farm research trials to evaluate the effectiveness of the Harrington seed destructor. The results were impressive with greater than 90 per cent seed destroyed in the chaff of a number of different weed species.

Working 9 to 5: What a way to kill those weeds!

Reading Time: 3 minutes Competitive broadleaf weeds, specifically lamb’s quarters and velvetleaf, are easier to kill when herbicides are applied during the day, generally between the hours of 9 a.m. to 6 p.m. Most will joke that this is simply because civil servants like me do not want to work before 9 a.m. and after 6 p.m. Touché. However, […] Read more

Pest Patrol: Choosing winter wheat herbicides

Controlling weeds when you've underseeded red clover

Reading Time: 2 minutes Question: Besides Buctril M (bromoxynil/MCPA), are there other winter wheat herbicides that we can use to control weeds when we have underseeded red clover? The short answer is, “Not really.” There are other broadleaf herbicides including MCPA sodium and MCPA/MCPB that can also be used on winter wheat that is underseeded with red clover, but […] Read more

A valued colleague, @wheatpete, goes on to the next 
chapter of his distinguished career

That’s the price you pay for being passionate, unafraid to share an opinion and continually challenging the industry to step up their game. Not […] Read more


A flowering nipplewort plant found in glyphosate-tolerant corn in late June of 2014. This would indicate that this particular population has a winter-annual life cycle. As such, management should be targeted in the fall when the plant is in the smaller and more-susceptible seedling rosette stage.

Pest Patrol: controlling nipplewort

I have nipplewort, and it seems to be very tolerant to herbicides. Any tips for controlling it?

Reading Time: 2 minutes The common name of this weed may seem risqué but understandable. The plant’s milky latex, which is believed to have anti-inflammatory and antiseptic properties, was allegedly used in the 16th century to soothe cracking and inflammation of nursing mother’s breasts. Fast-forward to the present day and it’s thought more of as an annoying weed that is […] Read more

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.

Pest Patrol: options for tufted vetch

Can I do anything to get rid of vetch 
before seeding soybeans?

Reading Time: 2 minutes Tufted vetch (Viccia cracca) is a weedy perennial legume that is difficult to manage in cropping systems that use reduced tillage and particularly when annual legume crops like soybeans are grown. Tufted vetch also exhibits high tolerance to many herbicides, most notably glyphosate. A rate response study was conducted by the University of Guelph over […] Read more
