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

Plant health is affected by a multitude of factors, making identifying problems in a field a daunting task.

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

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
