The pea leaf weevil can cause devastating economic losses to both peas and faba beans. Though the adult beetles feed on these crops after overwintering in perennial legumes, it is actually the larvae that cause the greatest damage. Larval feeding occurs on Rhizobium nodules for roughly six weeks. This may limit or completely inhibit nitrogen-fixation… Read More

Results from a seed test could shape several management decisions made at seeding — from fine-tuning the seeding rate to determining the viability of the seed lot for seed at all. Though damaged seeds and vigour issues can be assessed, arguably the biggest factor for consideration in seed test results is the type and level… Read More
Let’s say the planning stages go like this: crop rotation, variety selection, seed testing, determine seeding rate and so on. If you’re a farmer who doesn’t typically test seed or who may be thinking of skipping this step in an effort to save on costs, this episode of the Pulse School is for you. In… 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
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
Applying fungicides to pulses early is crucial, particularly with polycyclic diseases which can spread through the canopy quickly. Downy mildew is one of these polycyclic diseases, but it’s trickier than most to control due to a few factors, says Kan-Fa Chang, research scientist with Alberta Agriculture and Rural Development. Chang says limited fungicide options makes in-crop… Read More
Does your farm have the cleavers? In this episode of the Pulse School, Ken Sapsford, research assistant at the University of Saskatchewan, explains issues surrounding the abundance of cleavers across the prairies. With the shift towards no-till farming practices, cleavers, which were once considered a summer annual, are now overwintering, particularly in the presence of… Read More
Each seed treatment product protects against a specific list of diseases or insects, but it’s the overall impact of early season protection on stand establishment that has much more far-reaching impacts than simply avoiding disease infection. In this Pulse School episode, Wes Anderson, agronomy manager for Richardson Pioneer, does outline which seed treatments will protect… Read More
In order to have an effective fungicide strategy, the approach behind it has to be more preventative than reactive. That approach can be a little scary sometimes when spraying based on a risk assessment instead of seeing actual symptoms. It’s an approach that can leave you wondering if you did the right thing, but if… Read More
A good fungicide program is important in your pulse crops. Variety selection, rotation, product selection and proper application of that product should all come together to get you the most bang for your fungicide buck. While all of those elements are vital to the health of your crop, your whole program could suffer if the… Read More
Getting to know your field should start early. You can most effectively notice when something has gone wrong with your field if you are familiar with it. The benefit of starting that process early is that you can see things like crop establishment issues and other stresses on the plants that you might not be… Read More
Weed control in pulse crops is an area that has to be managed well in order for your crop to reach its potential. Pulse crops are not very competitive once put into the ring with invasive weed species. While they’re not exactly the 98-lb weakling of the agricultural world, they do need the playing field… Read More
Spray timing, plant population and desiccants are very important elements to manage when it comes to weed control and the proper development of your pulse crop. According to Weed Biologist Eric Johnson of Agriculture & Agri-Food Canada, producers should start to plan weed control 2 to 3 years ahead. What that means is that in… Read More
We’ve talked before about the damage the pea leaf weevil can do, but the current economics of peas add a sense of urgency to producers scouting and control strategies. With pea prices being as strong as they are currently, the economic threshold for spraying for the pest is lower than it ordinarily would be. Taking… Read More
This years mild winter has brought a number of concerns to producers minds in the area of pests. The general thoughts and feelings being that the mild weather would either help pests to over winter more easily leading to increased numbers or that the conditions would lead to pests being out and about much earlier… Read More
