Unlike bertha armyworm, which is discussed here, diamondback moths are quite small and are carried on winds that come up from the south. This makes monitoring and scouting for the pest somewhat more difficult than others, as pests that overwinter have a more easily anticipated emergence timeline. Beyond monitoring, there are some very telling ways... Read More

With high fusarium levels threatening the quality of this year's wheat crop, Peter Johnson, cereal specialist with the Ontario Ministry of Agriculture and Food, is urging farmers to take the grain off early so as to minimize the growth and spread of the disease. That's all good and well, say farmers, but the crop is... Read More
What's above ground is a direct reflection of what's below when it comes to crop development, but under excellent growing conditions you may not notice significant differences between plants with good root development and those with poor development. At the onset of drought or nutrient stress, for example, you'll start to see a difference right... Read More
Thriving in wet, soggy soils (and thus seldom acknowledged as a problem-pathogen in Canada), aphanomyces is difficult to differentiate from other root rot microorganisms based on symptomology alone. Molecular techniques and identification of spores in the lab are the best means of identification, and as of right now, there is no commercial test available for... Read More
The hybridization of crops is one of the first big stepping stones to major advancements in crop yield, as hybrid vigour really does create offspring greater than either of the parents. Hybrid breeding of corn and canola varieties has led to yield jumps in the leaps vs. the incremental gains made through straight crosses. But... Read More
Having trouble deciding whether or not to spray for soybean aphids? Well, you're in luck: there's an app for that! In this episode of Soybean School, Tracey Baute, emtomologist with Ontario Ministry of Agriculture, Food and Rural Affairs, introduces The Aphid Advisor App, which uses pest and beneficial insect data collected by the user, in...

By now you're fully aware of the importance of monitoring insect pests in your canola. So, you've collected and assembled your sweep-net, now what? The standard technique for sweeping is one 180 degree sweep for every quick step through the canola field (accompanied by the odd fall, of course). Sounds simple (and perhaps slightly embarrassing),... Read More
At the end of the year, when all is said and done and you're looking at what your corn crop produced, it's a really good exercise to think about where yields are now vs where they were. Then start to stack up everything that went up against it from late planting to cool temperatures, hot... Read More
The wheat midge (Sitodiplosis mosellana) is a pest found in wheat that can have significant impacts on your yields and grain quality. These insects overwinter as larvae and emerge as adults from their pupal stage in late June to early July (typically 600-900 growing degree days (GDD), ask your agronomist how many GDD`s we have...

Have you been keeping an eye on the bertha armyworm monitoring trap numbers in your area? As we crawl closer to mid-July, it's important to be aware of regional risks, and have a good understanding of proper scouting techniques and spray timing. "You're going to have your best success spraying at night," says John Gavloski,... Read More
