In-grained pest resistance

Wheat midge are a problem in much of the Prairies and next year producers may seek wheat varieties that can limit damage from those insects. Todd Hyra, western business manager for SeCan, urged producers to note its CWRS variety AAC Oakman VB, which carries tolerance to both midge and sawfly, but it is not available […] Read more

Wireworms remain persistent pest for producers

Nestled in the soil and hard to kill, this insect is a constant headache for growers across Western Canada

Glacier FarmMedia – They’ll survive things that would kill other crop pests. Some species will eat each other. If food is scarce, they might reverse molt to become smaller and harder to starve. They’ll go after grain crops, potatoes, onions, carrots, strawberries or almost any other field crop. Their tendency to feast on germinating seeds […] Read more

Canola council urges vigilance with flea beetles

Flea beetle damage was relatively low last year compared to the crushing pressure of previous seasons, but producers can’t afford complacency. “There was less foliar insecticide used for flea beetles than the previous years, and maybe less flea beetles to some degree, but there were still a lot of flea beetles out there,” said Manitoba […] Read more

Potential exists for high spring ’hopper hatch

Latest forecast indicates migratory grasshoppers likely to emerge in a large cluster this spring rather than more gradually

MEDICINE HAT — The number of crop-damaging grasshoppers has been rising in southern and eastern Alberta since 2021 and conditions favour the trend to continue, according to the latest forecast. The warm, dry fall and early winter may have created a situation in which most southern Alberta grasshoppers have entered diapause, a type of hibernation […] Read more
