Field scouting is an essential part of integrated pest management, used to examine all aspects of crop production to achieve optimum yield. Scouting is the process of monitoring crop development in each of your fields to evaluate crop concerns and economic risks from potential pests and diseases.

If “technology transfer tool” can be defined as a way to get information into the hands of as many people as possible, weather-based disease forecasting models are the perfect example of how this works in practice.

Is there an interaction between seeding rate of pea and lentil, disease incidence, and fungicide effectiveness? This question was the driving force behind an Agricultural Demonstration of Practices and Technologies (ADOPT) Program project.

Though soybeans are Ontario’s largest field crop, 2016 presented difficult conditions, with hot, dry weather continuing until August in many areas. As a result, soybean production was down overall, from 3,728,500 tonnes in 2015 to 3,374,700 tonnes in 2016, as reported by Statistics Canada.

According to panelists at the Canadian Global Crops Symposium, the Canadian soybean industry needs to improve its protein levels as well as the perception of its soybeans in the global marketplace.

“Western Canada has gone from having not optimal to better protein levels over time and we’re getting very close to the average U.S. protein,” said Jim Everson, executive director, Soy Canada. “Unless we get protein levels up, we’re likely to take discounts on international markets.” | READ MORE

Although stripe rust is not a new disease, it was rarely considered an economic concern, except in some irrigated crops in southern Alberta. However, in 2011 stripe rust caused serious economic impacts in both Saskatchewan and southern Alberta. Unusually high spring precipitation resulted in high moisture conditions in spring wheat crops, which created favourable crop canopy conditions for the pathogen. Another factor was the large diversity of pathogen races that appeared in 2011, including a race virulent on Yr10, a major gene in the popular winter wheat AC Radiant. Researchers are trying to learn more about the disease and find ways to help both plant breeders and growers manage the disease.

In Saskatchewan, durum wheat growers have experienced serious losses to Fusarium head blight (FHB) in recent years. Although FHB infection was considered quite severe in 2014, infection in durum wheat crops was even worse in 2016. The weather conditions were a significant factor, but the high levels of FHB were compounded by the adoption of shorter rotations, a lack of highly resistant varieties and the availability of fungicides that only suppress the disease.

The relationship between bees and canola is strong, just ask any honey producer. But what benefits do canola growers receive from those colonies parked at the corner of a field? New research in Alberta is delving in to that sweet subject.

A relatively new root rot disease in pea and lentil crops is steadily expanding across Alberta, Saskatchewan and Manitoba. Caused by the soilborne “water-mould” pathogen Aphanomyces euteiches, the root rot can cause infection any time throughout the growing season under the right field conditions. Currently, longer crop rotations are recommended, but few management options are available.

A coordinated effort to understand plant microbiomes could boost plant health and agricultural productivity, according to a new Perspective publishing March 28 in the open access journal PLOS Biology by Posy Busby of Oregon State University in Corvallis and colleagues at eight other research institutions. | READ MORE

There’s good news for flax producers: if your soil has reasonable nitrogen (N) fertility, you can save on fertilizer costs because pushing the N rate seldom results in increased yield. The bad news is that flax, unlike canola or cereals, is not very responsive to N application, so yields are hard to push higher. Researchers are trying to find the compromise where N application rates provide optimum flax yield.
"Most of the barley varieties that we grow in Western Canada tend to be malt varieties; growers are hoping to get the extra premium if it makes malting grade. But only about 20 per cent of the acres sown to malting barley each year actually make malting grade,” says John O’Donovan, a semi-retired research scientist with Agriculture and Agri-Food Canada (AAFC).

Prairie farmers primarily use urea (46-0-0), anhydrous ammonia (82-0-0), or liquid urea-ammonium nitrate (UAN) (28-0-0) as their nitrogen (N) fertilizer sources. Nitrogen fertilizer can be lost due to volatilization, denitrification or leaching, depending on how the N is applied and the weather conditions after application.

The Ontario Winter Wheat Performance Trials have always been designed to give growers useful information to help them make decisions, but the historical data is equally helpful because it shows how varieties perform over time under diverse conditions. The intensive management data introduced in 2013 proved invaluable in 2016 and could have an impact on growers’ choices in the future.

Cover cropping is a promising approach to reduce some of the negative environmental impacts of production agriculture. Cover cropping also has its risks, especially if dying cover crops encourage disease pressure that passes on to the next crop. Researchers set out to describe the microbiology of dying rye cover crop roots and how their microbial communities changed over time in a field setting. What they unexpectedly discovered was the potential for elevated disease risk in corn following the use of cereal rye as a cover crop. | READ MORE

A dry spring hindered crop growth and gave a leg up to early season insects like cutworms and flea beetles in some areas of the Prairies in 2016. Mid-season growing conditions favoured wheat midge.

Root rots are a major, yield-limiting problem for Prairie soybean growers, so western Canadian researchers are working on a range of studies, such as evaluating crop rotations and screening soybean lines for genetic resistance, to help improve root rot management. Now, a project led by Fouad Daayf, a plant pathologist at the University of Manitoba, is extending that range of research into some fascinating new areas.

Moving to wider row spacing for no-till wheat can make it easier to direct seed in between rows and can create better seedbed conditions. Generally, narrow row spacing is expected to give the greatest potential grain yields for the majority of crops, however narrow row spacing requires more openers, more draft, more energy, more cost, more maintenance and more residue clearance.

Tree-based intercropping – growing trees together with crops – is a historical agricultural practice. These days primarily smallholder farmers use it in tropical systems, but researchers are focused on potential applications in the temperate soils of southern Ontario and Quebec.
