New herbicide tackles glyphosate-resistant Canada fleabane

There’s a new tool available for growers in the fight against herbicide-resistant weeds, such as Canada fleabane. Corteva Agriscience has launched Elevore, a Group 4 herbicide option for pre-plant burndown of broadleaf weeds, including glyphosate-resistant Canada fleabane, in both field corn and soybeans. Last week at Canada’s Outdoor Farm Show, Dave Kloppenburg, Corteva’s Canadian category leader… Read more »

Managing clubroot? Choose broad-spectrum genetic resistance

Where clubroot is a risk, are you stretching canola rotations or using a clubroot-resistant variety? Realistically, you should be doing both — and not all clubroot resistance is created equal. While industry and plant breeders should be commended for the speed at which clubroot-resistant varieties were introduced, we know now that that early, single-gene resistance… Read more »

Corn School: Harvest quickly to limit losses to gibberella

If you’re noticing a little fuzzy trouble with your corn crop this year — you’re not alone. With rainfall after rainfall at pollination (but not before!), the weather created perfect conditions for gibberella infection and spread. If you’ve scouted your corn crop and have found pink mould growth at the tip of the cob, chances are… Read more »

Saskatchewan agriculture associations collaborate to urge re-evaluation of strychnine

The 90-day consultation period regarding access to strychnine for rodent control in Canadian fields is drawing to a close. Back in July, Health Canada proposed the de-registration of the chemical, often used to curb rodent population in farmers fields as the department found the chemical was also causing harm to species-at-risk, such as the swift fox and the burrowing… Read more »

Resistance Management School: It’s all about diversity

Herbicide resistance is nothing new to Ontario farmers. It all started in 1973 when triazine-resistant lamb’s-quarters were found on a farm near Ripley, Ontario. Group 2 herbicide-resistant weeds were first documented in 1996. Fast forward to 2018, and we find that the province is now home to a host of glyphosate-resistant weeds including Canada fleabane, giant… Read more »

Wheat School: Smart(phone) help for cereal aphid scouting

Agriculture and Agri-food Canada (AAFC) has, until now, never developed an app. Until now, that is, with the launch of a new app called CAM. The Cereal Aphid Manager (CAM) is the first app ever developed by AAFC. Dale Leftwich, RealAgriculture’s Saskatchewan field editor, met with Tyler Wist, field crop entomology research scientist with AAFC,… Read more »

Wheat Pete’s Word, Sept 5: Big yield predictions, gibberella risks, and selling potash

If you’ve heard tell of some record yield estimates out there, let’s all remember that the crop sure isn’t in the bin yet, says Peter Johnson, host of Wheat Pete’s Word. It seems that some of the good spots look GREAT and some of the poor spots are turning out better than anticipated. When it… Read more »

Manage resistance by rotating modes of action

Resistance One of the many things to think about while managing herbicide resistance on your land is the rotation of modes of action. Many growers don’t realize how much Group 14 herbicide they are using. While there are many common add-ins used with glyphosate, more than half of them are from Group 14 — which,… Read more »

Corn School: Will wet weather bring late-season disease?

Ontario Ministry of Agriculture, Food and Rural Affairs plant pathologist Albert Tenuta is gearing up for his annual pre-harvest corn disease survey, and he’s optimistic leaf disease will not have a significant impact on the 2018 corn crop. Some growers have raised concerns that a rainy late July and August could lead to a flood… Read more »

Soybean School: Tips to keep soybeans free from volunteer canola

When glyphosate-tolerant soybeans made their appearance on the Prairies people were very excited about the crop and the potential for good weed control. It turned out, though, that there was one fly in the ointment, and that was volunteer glyphosate-tolerant canola. Although early attempts at soybeans sometimes looked more like canola fields, there are some… Read more »

Health Canada proposes ban of remaining two main neonics

Health Canada has proposed banning two of the most commonly used neonicotinoid insecticides (neonics) used in Canadian agriculture in the next three to five years following a review of their impact on aquatic insect species. The proposal published on Wednesday would end outdoor agricultural and turf uses for clothianidin, and all outdoor agricultural and ornamental uses… Read more »

Soybean School: Trade the hula hoop for boots and a measuring tape

What’s the gap between your soybean seeding rate and final stand count? It’s a key management consideration if growers want to get a handle on what’s happening in their fields and increase yields, says Syngenta agronomic sales rep Marijke Van Andel. When growers discover there’s a 20 percent gap between seeds planted and the final… Read more »

Xarvio launches weed identification app

What if you could just point your phone at a weed and the phone would tell you what you were looking at? At one time it was a huge breakthrough to be able to take a picture of a weed and send a text message to an agronomist. It still is in fact, but sometimes… Read more »

Canola School: Clubroot cases popping up in Manitoba

Now is the time to check canola fields for symptoms of clubroot, as a new streak of cases have been found in Manitoba over the last few weeks. The clubroot map for the province will likely be changing this fall, as the soil-borne disease has been found in a new municipality, says Holly Derksen, field… Read more »

Prairie pest finds unlikely ally in the federal government

There is often a good natured debate about what they are called. Officially, they are the Richardson Ground Squirrel. In polite company they are most often called gophers. In farm country, what they are called is mostly unprintable, especially the adjectives. That being said, the much-maligned pest may have just found an ally in the… Read more »
