Cutworm, flea beetle pressure piling on Prairie crops

CNS Canada — High levels of cutworms and flea beetles are damaging crops in Western Canada this spring, according to Manitoba’s crop entomologist. Manitoba growers started noticing damage from cutworms this week, said John Gavloski, extension entomologist for Manitoba Agriculture, Food and Rural Development in Carman. “They were there in the fields, but they were

Be on the lookout for flea beetles, cutworms and wireworms, all of which can take a bite out of yields early in the growing season, says John Gavloski, entomologist with Manitoba Agriculture, Food and Rural Development (MAFRD). Canola is especially vulnerable to flea beetle damage during the cotyledon to second true-leaf stage, Gavloski said during

Pests likely to survive Manitoba winter

CNS Canada –– Sufficient snow cover will likely help insect crop pests survive the winter in Manitoba, despite a recent bout of extremely cold weather. “Snow is a great insulator, so even though we have had some quite cool temperatures the last several weeks, where the insects are beneath the snow it’s actually nice and

In addition to flea beetles, farmers should be scouting for cutworms, wireworms and grasshoppers

Flea beetles are munching on Manitoba canola crops but a provincial entomologist says the damage may look worse than it is. If there’s more than 25 per cent feeding damage after the canola crop has been planted for at least three weeks, an insecticide application could be economic, John Gavloski said in a Manitoba Agriculture,

Swede midge threat looms over Manitoba canola crops

A deceptively tiny bug can wreak non-stop havoc in canola

If you thought clubroot was scary, get ready for Swede midge — a voracious mosquito-like bug that can wreak havoc with your canola yields. First found in North America in 2000, and has appeared in low numbers in Manitoba in 2007 and 2013, said Julie Soroka, a Saskatoon-based entomologist with Agriculture and Agri-Food Canada. “The

Pests make an early appearance

Be watchful for flea beetle feeding Striped flea beetles (Phyllotreta striolata) have been emerging and feeding on volunteer canola since late March, provincial entomologist John Gavloski says in the first insect and disease report of the season issued April 27. “We often see striped flea beetles emerge earlier than the crucifer flea beetle (Phyllotreta cruciferae)


Flea Beetles Feasting On Canola

Flea beetles have been feasting on canola seedlings in Manitoba. Heavy infestations have warranted foliar insecticide treatments, Manitoba Agriculture, Food and Rural Initiatives says in a June 13 report. “Even if Helix or Prosper seed treatments have been used, some minor feeding to leaves and cotyledons is normal, as the flea beetles needed to ingest

Beetles Find It Tough Going In Manitoba

Manitoba has been using biocontrol beetles since 1988 in Spruce Woods Park, but the results haven’t been encouraging. In the 1990s, there were 3,500 beetle releases, mainly the black and brown flea beetle species, said John Johnson, president of the Manitoba Weed Supervisors Association. In 1996, 350,000 were brought in from a capture site in
