Powdery scab, caused by Spongospora subterranea, thrives in cool, moist conditions and can significantly impact potato crops by forming lesions on tubers and galls on roots.

Powdery scab a puzzling potato problem
Biosecurity, such as avoiding the use of manure from livestock that ate infected potatoes, is a must
How potato pests find ways around insecticides
Resistance to insecticides is complicating pest control, prompting experts to advocate for integrated management strategies
Several mechanisms allow insects to survive pesticide applications — for example, metabolic resistance, in which the pest detoxifies the insecticide faster than a susceptible individual, or target-site resistance, in which the receptor sites affected by the pesticide are altered.

Red clover: A forage crop worth a second look
Cool-season adaptability, strong yields and soil benefits may make it an attractive choice

Get your kochia under control — by burying it
An AAFC scientist found covering kochia with chaff was the most effective at killing it
For the last few years, AAFC scientists in Saskatoon have been studying methods to “artificially” bury kochia seeds in the soil as a possible way to control the tumbleweed.
Cutting the nitrous oxide emissions without losing yields
Better nitrogen management promises to both protect crop yields and reduce greenhouse gas emissions from fertilizer; new research looks to verify how much difference it actually makes
Better nitrogen management promises to both protect crop yields and reduce greenhouse gas emissions from fertilizer. New research looks to verify how much difference it actually makes.
Grow forages, starve weeds
Forages disrupt weed routines and slow herbicide resistance — if you can use them
“Forages actually can be used to combat resistant weeds,” Kim Brown says. “A perennial forage stand will last for several years, but in a spring annual crop rotation, you’re dealing almost exclusively with annual crops most of the time.”
