Clubroot removed from official declared pest list in Sask.
Richardson’s ground squirrel, grasshoppers and the warble fly are also no longer on the province’s list of declared pests
REGINA — Clubroot is among several pests the Saskatchewan government has now deregulated.

Crops ‘look good’ but slow
SASKATOON — Statistics Canada’s latest satellite-based map of vegetative growth in the Canadian Prairies is missing the colour green. The Crop Condition Assessment Program (CCAP) map for the week ending June 16 was all yellow and brown.

System controls ’hoppers on pasture
Reduced Agent and Area Treatments method can cut insecticide use in half and still kill most grasshoppers
WINNIPEG — Grasshoppers, as their name suggests, hop from place to place in grassy fields. By taking advantage of that natural behaviour, University of Wyoming scientists have devised a way to control grasshoppers on pastures with a smaller volume of pesticides. The method is called Reduced Agent and Area Treatments (RAAT), in which farmers apply […] Read more

Changes could be in place by spring 2024. SaskCanola requested changes a year ago to how clubroot is treated. The organization asked for clubroot to be removed from the Pest Control Act where it had […] Read more

Grasshopper numbers middle of the road; vary region to region
Grasshopper infestations across Alberta are patchy this year, following a cool April and scorching May with small pockets of moisture, according to a University of Lethbridge entomologist. The usual hotspot for grasshopper populations in southeastern Alberta got a late start compared to the rest of the province, said Dan Johnson. He cited a wet early […] Read more
