Insect numbers low, flea beetles requiring some control in canola

Manitoba Insect & Disease Update for May 31

Insect pest concerns are currently low overall. There have been some insecticide applications for cutworms on corn and soybeans in the Central Region, and on peas and lentils in the Northwest. Some species of cutworms, such as dingy cutworm, have started to turn to pupae in some field. Cutworm staging can be quite variable depending on the dominant species

While forest tent caterpillars are high in number this year, they are not a direct a threat to most crops.

Cutworms growing larger, stripe rust detected

Manitoba Insect & Disease summary for June 8

Insects Cutworms are getting larger and have been an issue in some fields. The highest level of damage appears to be in the Northwest, where there has been some reseeding because of cutworm feeding. Flea beetle feeding continues, although foliar use of insecticides for flea beetle management has not been widespread. In many fields plants are now getting to stages more tolerant to feeding by flea beetles. Plant Pathogens Stripe rust has been detected


Cutworms, flea beetles a concern for canola growers

Cutworms, flea beetles a concern for canola growers

Manitoba Insect & Disease Update for May 25

Insects Cutworms and flea beetles on canola are the insects of greatest concern currently. Seed treatments should still be effective against flea beetles in most canola fields, although scouting for feeding damage is encouraged, especially in the earlier seeded fields where seed treatments may soon start losing effectiveness. Cutworm levels are quite variable, hard to

Flea beetles in canola and cutworms in several crops were the main insect problems in Manitoba in 2015, but overall it wasn’t a terrible insect year for Manitoba farmers, says MAFRD entomologist John Gavloski.

Alfalfa weevils, army worms, corn borer, soybean aphids and 
lygus bugs showed up in some fields too

Insects didn’t take a massive bite out of Manitoba crops in 2015, but there were some nibbling problems caused mainly by flea beetles and cutworms, says Manitoba Agriculture, Food and Rural Development entomologist John Gavloski. Alfalfa weevil populations were high enough in many alfalfa fields to cause economic damage and army worms were a concern

Flea beetles in canola and cutworms are the insects of most concern

Summary Flea beetles in canola and cutworms continue to be the insects of greatest concern. Insecticide applications and some reseeding have occurred because of feeding by these insects. Monitor emerging crops for seedling disease. So far populations of disease vectors have been low. Aphid vectors of barley yellow dwarf have not been seen or reported, and only small populations of

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 three early-season crop pests

cutworms and wireworms for Manitoba farmers

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

Later canola seeding could mean less flea beetle damage

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,
