Wheat Pete’s Word, May 10: Quality forage timing, cold temp fallout, and two-pass fungicide strategy

This week’s (almost!) cross-Canada Wheat Pete’s Word is packed full of great questions, worries about cold temperatures, solid timely answers on field management, and at least one alert, alert, alert! Your host Peter Johnson tackles questions on harvesting cereal rye (soon! this week!) while keeping compaction in mind, if corn seed is going to be… Read more »

Wheat Pete’s Word, May 3: Rust alerts, wet weather, and the philosophy of seeding rates

We’re kicking off May with wet, wet weather both at home and south of the border, and not one but two alerts for very early disease detection in Ontario’s Bruce and Essex Counties. Peter Johnson, your host of Wheat Pete’s Word, also has cautions on using saved soybean seed from the 2016 crop, why you… Read more »

Wheat School: Evolving Stripe Rust Beats The Heat

Wheat stripe rust is thriving in Ontario and growers are asking what can they do to manage a growing scourge of what European growers now refer to as ‘Yellow Death.’ In this episode of Wheat School, Real Agriculture agronomist Peter Johnson takes you to the Ontario Cereal Crops Committee performance trials near Harriston, Ontario where… Read more »

Syngenta Launches Fungicide With Three Modes of Action

Syngenta has announced plans to bring the first three-mode-of-action foliar fungicide to farmers in Eastern Canada this spring. Trivapro features three active ingredients, including one new active — azoxystrobin (Quadris – Group 11), propiconazole (Tilt – Group 3), and benzovindiflupyr (Group 7 SDHI), known as Solatenol. Solatenol was approved for use on corn, soybeans and… Read more »

Wheat School: Identifying and Managing Stripe Rust

Stripe rust was reported in early spring in Alberta, likely having over-wintered in the southern part of the province, and now there are reports in Manitoba of the fungus arriving on winds from the U.S. In this Wheat School episode, Holly Derksen, plant pathologist with Manitoba Agriculture, Food and Rural Development, describes how stripe rust inoculum moves north from the… Read more »

Wheat Pete’s Word — May 20: Weed Escapes, Spray Timing and Manganese on Wheat

The 2015 planting season is moving right into spraying season, as this week’s update from Wheat Pete includes discussion about early weed control in dry conditions, critical weed-free periods for corn and soybeans, and manganese deficient wheat. Whether it’s lamb’s quarters, pigweed, ragweed or foxtail, “you name it, it’s out there coming gangbusters,” says Peter Johnson. And… Read more »

Wheat School: Economic Thresholds for Stripe Rust

Wheat leaf diseases aren’t always capable of overwintering in Canada. Besides often needing shelter from harsh winter conditions, the pathogens also suffer from a relative lack of alternate hosts. This year, however, stripe rust — a disease caused by the fungus Puccinia striiformis — took sanctuary in winter wheat fields in parts of the prairies, safe… Read more »

Wheat School: Stripe Rust ID, Risk Factors & Over-Wintering

Leaf rusts come in many shapes and strains and can be particularly hard to avoid, as the pathogen blows in from parts unknown (well, we know where, but that turn of phrase sounds better). What’s perhaps more troubling is there is evidence that stripe rust may have over-wintered in parts of Alberta this year. Over-wintering… Read more »

Wheat School: Do you Know your Variety’s Rust Resistance? It Matters.

Rust in cereals, and especially stripe rust, is a disease that it can be easy to allow to drop off the radar. After all, the spores are carried by wind and may not reach your growing region in time to really cause an issue. What’s more, decent varietal resistance exists for many races of rust,… Read more »

A 3-Point Plan for Avoiding Leaf Disease Losses

It’s that time of year where we transition from killing weeds to protecting our crops from diseases. Growing conditions across much of Western Canada have been good, with adequate moisture (to too much moisture!) and warm temperatures; this is excellent for the crops, but also creates a conducive environment for diseases to thrive. Scouting: As… Read more »

DuPont Enters Strobilurin Race

After a chemical manufacturer discovers a new crop protection chemical family, the normal response within the industry is to focus research on better versions of the same chemistry. This typically results in several new brands being launched, each claiming to be slightly better than the last. This seems to be the case with DuPont’s new… Read more »

Wheat School – How Do I Know If It’s Stripe Rust?

Stripe rust is the new big bad disease on the block. Don’t get me wrong, it’s not “new” in the sense of just arriving on the scene, but it is new in the sense that it is making it’s presence known lately. As with anything that’s currently in the spotlight, there tends to be a… Read more »
