Proper staging is critical when applying in-crop herbicides in corn, but there are multiple ways to measure corn’s growth stages, and herbicide labels don’t always use the same method. Agronomists often use the “leaf collar” — or V-stage — method to describe growth stages, while others use plant height. However, herbicide labels often refer to… Read More
When’s the best time of day to spray herbicides? Morning, noon, or night? University of Guelph weed scientist Dr. Peter Sikkema says that every herbicide has a time-of-day effect but generally speaking, growers get the best weed control at 3:00 pm in the afternoon. That’s Sikkema’s conclusion based on time-of-day efficacy trials he conducted using… Read More
A spring of extremes — first cold, dry and windy, then hot, dry and windy — has resulted in weeds getting a head start in many soybean fields in the soybean-growing areas of Western Canada. While wind and cold temperatures delayed burnoff applications at the start of the season, questions about when to spray in… Read More
Will nozzle type solve the problem of getting efficacy while spraying T3 fungicides? There’s plenty of work done on the right nozzle for this job, but what are the other factors that lead to an efficacious application for controlling fusarium? In this Wheat School episode, our resident agronomist Peter “Wheat Pete” Johnson is fired up… Read More
With T3 fungicide application timing approaching to control fusarium in Ontario’s wheat crop, many growers are wondering whether to spray or not to spray. With the hot, dry Ontario weather pushing into late May, there’s little or no disease in the crop and disease levels could decline further if moisture continues to be scarce. For… Read More
Dry spring planting conditions have many growers wondering how their soil-applied residual herbicides will perform, as the weather continues to heat up with little meaningful rain in sight. Research by University of Guelph weed scientist Dr. Peter Sikkema indicates pre-emergence herbicides will still deliver significant value for growers in dry spring conditions. He notes that… Read More
As we approach the first long weekend of the summer season, farmers are thinking about relaying winter wheat and barley for forage, protecting N on dry ground, and skipping a pre-emergent herbicide pass. As to whether all or some (or none) of those are good ideas, Peter “Wheat Pete” Johnson has the answers in this… Read More
See and spray technology, recirculating booms, and pineapples — that’s just a few of the topics discussed in this episode of The Agronomists. To tackle what’s new in sprayer tech and how to do the best job spraying, there are no better experts to ask than our guests than Jason Deveau and Tom Wolf of… Read More
With winter wheat progressing rapidly through its growth stages in Ontario, RealAgriculture agronomist Peter Johnson is advising growers to keep a close eye on the crop. With crop development running 10 days ahead of schedule, Johnson says wheat fields need to be scouted to make critical management decisions to optimize yield. On this episode of… Read More
The roller coaster ride continues for Ontario’s winter wheat crop. It’s been a spring full of weather highs and lows but AGRIS Co-op agronomist Dale Cowan says the development of the crop is running about 10 days ahead of schedule in the southwest region of the province. Cowan told agronomists, researchers, and agribusiness reps gathered… Read More
As farmers begin to hit the field in Canada, ensuring adequate supplies of crop protection products is essential for the growing season. As retailers get product in place, growers are hearing of potential shortages of glufosinate and glyphosate in the U.S., both of which are critical early in the growing season. These two products touch… Read More
Early spring weather has left some wheat feeling the burn of products applied before cold nights in Ontario. Out west, many farmers are still hoping for moisture before getting rolling for the #plant21 season. For this week’s Wheat Pete’s Word, host Peter Johnson reminds listeners to take fifteen minutes out of their day to phone… Read More
Kochia is one of the first weeds to emerge in spring. There are reports that 80 per cent of the kochia population emerges before anything else in a field. The fact that it emerges so early puts a lot of pressure on the pre-emergent herbicide options out there. In this Wheat School episode, Kara Oosterhuis… Read More
Starting the year off on the right foot requires a little bit of forethought and planning. When it comes to keeping a canola crop clean during the early stages of growth, there are some steps to take before even seeding the crop. Dr. Charles Geddes, research scientist in weed ecology and cropping systems at Agriculture… Read More
When it comes to weed control, getting it right is key for edible bean success. University of Guelph research shows, on average, weed interference can cause yield losses up to 56 per cent compared to 50 per cent in corn and 36 per cent in soybeans. When comparing edible beans and soybeans, U of G… Read More
