There’s no denying when a spray clean out has gone wrong — the streaky start to a spray pass with injured plants never seems to happen at the back of the farm, either. There are a few things at play, says Tom Wolf, co-founder of AgriMetrix and Sprayers 101. There’s the possibility of active ingredient… Read More

Scorching summer temperatures are great when you’re at the lake, but for the reproductive phase of canola, temperatures above 27 degrees C can cause heat blast. When that happens, any seeds that would have been fertilized during the very hot temps fail to form, dragging down eventual yield. As Justin Nanninga, from Neeralandia, Alta., explains… Read More
A flowering canola crop looks pretty and smells great — to humans and insects alike. Canola has a laundry list of insect pest species, from ones that target stems and leaves, to super destructive pests that destroy pods and ruin seeds. A sweep net is a humble tool, but one that when wielded by a… Read More
Each time farmers or agronomists are in the field is a chance to scout for disease symptoms. Unfortunately, fungicide products aren’t curative — and not every product can control every disease. Knowing what disease pressure is present or confirming one disease over the other is a key part of a canola disease managment plan. Disease… Read More
Sulphur is a critical nutrient for maximizing yield potential in canola, and since peak sulphur uptake for canola happens later in the growing season than peak nitrogen uptake, applying sulphate as late as early flowering can rescue yield that’s at risk to being lost to a sulphur deficiency. Heavy rains can result in canola not… Read More
While small plot research allows for well-controlled studies, it can be challenging for farmers to implement new findings at a farm scale. Variability in environment, soil, topography and equipment can change the outcome of practices that may have worked very well in small plots. One way to solve the issues experienced by growers when implementing… Read More
The time is coming when farmers will check an in-field diagnostic tool for presence of a disease or insect and know it’s time to apply a crop protection product. We’re not exactly there yet, but sensor technology and apps are advancing to the point where it’s possible to get diagnostics on a field-by-field basis. One… Read More
Work for the growing season doesn’t end with seeding. Soon after, it’s important to be out doing early season scouting in order to mitigate potential issues. There are two main things that a producer is looking for when early season scouting: one is to measure the success of the seeding operation, including how many plants… Read More
Soil testing is a best management practice when planning fertilizer rates, but a soil test is perhaps most valuable following extreme situations — very wet or drought conditions. As Mike Palmier of Max Ag Consulting explains in this Canola School episode below, three years of dry or drought conditions for his area of west-central Saskatchewan… Read More
Producers in much of Western Canada are looking forward to warmer weather to help crops advance through the early stages after a cool seeding season and delays in seeding. For canola, slow emergence and growth due to cool temperatures, combined with wind damage in some areas, makes tiny plants a sitting target for flea beetles…. Read More
