Prairie pest report says grasshopper risk low

This despite general upward trend in the populations across Manitoba and Saskatchewan

This year’s grasshopper threat remains light to very light across Manitoba, according to survey data released by the Prairie Pest Monitoring Network on April 27. The data is based on surveys done in 2019. These included nearly 3,200 grasshopper counts across the Prairie provinces between May 1 and August 31. Maps in the report show

Pests like the corn leaf aphid could be in areas thought free of it, according to new research.

Crop pests often missed as they move into new areas

Finding where pests exist in the early stages of movement into an area are key to control

Insects and diseases that damage crops are probably present in many places thought to be free of them, new research shows. Pests that have not been reported in a certain area are usually assumed to be absent, but analysis by the University of Exeter shows many pests are “currently unobserved, but probably present” (a likelihood


Grasshopper control continues in oilseed crops, hay yields seen significantly lower

Manitoba Crop Report and Crop Weather report for August 13

Southwest Region Warm temperatures this week have quickly advanced crop maturity, together with cooler than normal overnight temperatures. Rain over the weekend and into Monday occurred throughout the region but amounts varied from 0.4 mm at Lake Audy to 37 mm at Bede. Areas along Hwy 16 are still below normal moisture accumulation this summer.

Nine pests to watch for if you’re growing flax

Dr. James Tansey, Saskatchewan Agriculture’s insect specialist, reminded farmers at a Saskatchewan Agriculture conference in Weyburn, Sask., that “plants are not a passive part of the environment.” Flax produces poison in the form of cyanogenic glycoside (cyanide) that is toxic to several insects. However, your flax crop may still need some help protecting itself from

Corn, sunflower, soybeans enter reproductive phase, hay and forage yields far below normal

Manitoba Crop Report and Crop Weather report for July 23

Southwest Region Scattered showers and thunderstorms in the region brought some significant rain in few areas and very little in others. Day and nighttime temperature have been above normal, giving crops a big growth boost. Some yellowing occurring in fields due to wet conditions in low spots, but with improved conditions this past week, they


VIDEO: How to treat grasshoppers that have made the jump to your fields

What to look for when deciding to spray for the voracious pest

If you’re seeing plenty of grasshoppers in your fields, you’re likely far from alone. John Gavloski, entomologist with Manitoba Agriculture, said at the Crop Diagnostic School on July 9 that populations have been on the increase for about three years. So, what action should you take if you see these hungry pests eating your crop?

This Carolina grasshopper is a common sight on gravel roads but it’s not a threat to your crops.

Mistaken identity

Not everything that looks like a pest insect actually is

One of Manitoba’s best-known insect experts is reminding farmers to be sure of what they’re seeing when they scout. For example, that “wireworm” problem may not actually be a problem at all. Therevid larvae (the precursor to a large, hairy fly) are often mistaken for wireworms, provincial entomologist John Gavloski said during a May 22



Grasshoppers are on the move. When scouting fields for the insect, Manitoba Agriculture entomologist John Gavloski says be aware sometimes grasshoppers will be mainly on field edges as they move in from ditches.

Grasshoppers are on the move

When scouting, check farther into the field because sometimes the insect is concentrated in field edges


Grasshoppers are on the move looking for green vegetation to eat. The good news is they aren’t much interested in ripe cereal and canola crops, soybeans aren’t their preferred food and corn has so much leaf area it can withstand high populations, says Manitoba Agriculture entomologist John Gavloski. “It’s not an outbreak,” Gavloski said in

Aphid numbers this year have been a fraction of what was seen in 2017.

Manitoba sees low aphid counts

Last year was a bad aphid year for a variety of crops, but few problems have been noted this season

Last year’s aphid problems have become this year’s near absence. Farmers are not fighting with aphids this year, according to the province, a departure from last year when levels prompted insecticide applications in a wide variety of crops from wheat to canary seed. “We’ve got lots of people out looking for aphids and, in most
