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

Having trouble deciding whether or not to spray for soybean aphids? Well, you’re in luck: there’s an app for that!

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), but… Read More

Nobody is capable of identifying every nutrient deficiency, disease symptom, insect species or weed present. But,  anyone involved in production should clearly understand the ins and outs of scouting, and what you’ll need in order to ask… Read More

When it comes to marketing your hard red winter wheat, quality is the name of the game. That means protein. Increasing that protein in your wheat predominantly means nitrogen management. SEE MORE WHEAT SCHOOL EPISODES. In this episode of the Wheat School, Peter Johnson joins us to talk about the relationship between nitrogen and protein… Read More

Ascochyta blight is a disease caused by three species of fungi, which are very difficult, if not impossible, to differentiate in the field. Fortunately, diagnosis of a specific pathogen causing ascochyta symptoms is not usually necessary, as control measures are very often the same. Out scouting? Look for purple-brown lesions on the stem, tendrils and… Read More

Damage from soybean cyst nematode can be minor, but once this pest is established in a field, it’s there for good. Since being confirmed in Ontario about 15 years ago, the nematode moved throughout much of the soybean growing region. Knowing the nematode pressure level in your fields is essential to minimizing damage through the… Read More
