Mature soybean plants await harvest in Ontario.

Manitoba soybean growers battle spider mites

Two-spotted spider mites have been top of Manitoba’s soybean insect pest problems in patches of the province, but at least there are fewer grasshoppers than expected

Two-spotted spider mites have been top of Manitoba’s soybean insect pest problems, but at least 2025 has seen fewer grasshoppers than expected.

Manitoba’s lack of rain is stressing crops, fuelling pest pressure and slicing yield potential in soybean and pea fields

Manitoba’s pea and soybean acres are suffering in drought-stricken regions like the Interlake. Dry conditions are stressing crops, fuelling pest pressure and slicing yield potential.

Flea beetle control goes outside the box at Ag in Motion

Ag in Motion 2025 is live; farmers can check out experimental trials like this one, playing with trap crops and natural repellents for flea beetles in canola

The stops at the 2025 Ag in Motion farm show feature an entomologist experimenting with trap crops and marigolds as concepts to control flea beetles.

Farmer-friendly nematodes: Tiny worms for big canola pest control

Soil-dwelling nematodes could become a practical option for Prairie pest control against damaging canola insect pests like diamondback moth

Not all nematodes are equal in farm fields. Beneficial species of the tiny soil-dwelling worms could one day help beat back damaging canola insect pests like diamondback moth on the Canadian Prairies.





Striping along the body is a hallmark trait of true armyworm larvae.

Manitoba watches true armyworm migration

True armyworms blowing into Manitoba haven’t sparked alarm in 2025, but agriculture entomologists urge farmers to scout their crops anyway for the damaging pest insect
