Kochia control waning in North Dakota

Two popular products also widely used in Manitoba seem less effective

By
A North Dakota State University study showed that some kochia populations in western North Dakota likely have developed resistance to commonly used pre-plant burndown herbicides. For many years, no-till farmers have used Aim (carfentrazone) and Sharpen (saflufenacil) either just before or just after planting to control emerged kochia and other annual weeds. In Manitoba, carfentrazone is the active ingredient in Aim EC,

Late harvest hampers fall weed control efforts

Narrow regrowth window, cooling temperatures play role in limiting applications

By
Manitoba’s weed specialist says this year’s late harvest has thrown a wrench into many farmers’ fall control plans. Normally, it is recommended that farmers wait four to six weeks after harvest to allow weed regrowth before spraying. “This year, we just don’t have the calendar days to do that,” said Kim Brown-Livingston, Manitoba Agriculture and

By ,
Washington | Reuters — The U.S. Federal Trade Commission on Thursday sued two top pesticide manufacturers for allegedly entering into exclusive contracts with distributors that kept prices paid by farmers artificially high. The consumer watchdog agency was motivated to bring the case in part because rising costs and supply chain disruptions from Russia’s invasion of

Weeds in fields quickly outpacing crops

Late seeding and weather challenges make a big challenge even bigger

By
This will be a tough year for weed control. Late seeding into warm, wet soil is going to give rise to relatively fast crop emergence and leave little time to do any kind of pre-seed herbicide application. Complicating matters further, is the ongoing global herbicide shortage. In a ‘normal’ year, depending on the crop, that

Stocking up for a shortage-plagued spring

There’s a long list of ag products under supply strain while one of farming’s busiest seasons is about to ramp up

By
This isn’t going to be one of those springs where you can stroll into your local ag retailer and be confident you’ll be leaving with everything you need. Supply chain issues of all stripes have kept inventories of all kinds across the country depleted, even as spring approaches. The list of ag products facing supply

Pre-emergent products require care

These older formulations are effective but come with some risks too

By
Hitting weeds with a pre-emergence residual herbicide can be an effective way to keep them in check while they’re germinating and highly vulnerable. This gives your crop a head start by removing early competition but you have to consider carry-over if you’re going to manage a persistent herbicide in your soil, according to Kansas State

Comment: Doubling down won’t solve weed woes

Dicamba was supposed to solve weed problems – instead, it’s making farming harder

By
Farmers are stuck in a chemical war against weeds, which have developed resistance to many widely used herbicides. Seed companies’ answer – using more varied herbicides – is causing new problems. In October 2021 I was a guest on a popular podcast to discuss my recently published book, Seed Money: Monsanto’s Past and Our Food

With a looming chemical shortage, it’s going to be important to do more with less this spring

By
A host of seemingly unrelated incidents including another round of COVID-19, the upcoming Winter Olympics and the current world supply chain issues have brought about an odd perfect storm. The component chemistries that make up herbicides are harder to get, so herbicides are not as plentiful and they’re more expensive. Consequently farmers may have to

Management interference flagged in Environmental Protection Agency’s dicamba decision

Office of inspector general says decision ran counter to EPA’s Scientific Integrity Policy

By
Three senior United States Environmental Protection Agency (EPA) managers altered scientific documents to support the EPA’s decision to extend the registration of the herbicide dicamba in 2018, contrary to EPA’s Scientific Integrity Policy. That’s the conclusion of the EPA’s office of inspector general (OIG) in its report released May 24. The EPA’s decision to extend

Industry program helps avoid residue problems on exported crops

By
Canadian farmers are being encouraged to use an industry alert program to keep unacceptable pesticide residues on crops from spiralling into potential trade problems. The voluntary program called Keep It Clean informs producers about which products to use on cereal, oilseed and pulse crops and which ones to avoid so as not to exceed maximum
