Eastern Prairies’ wet conditions may curb insect pest risk

Late-seeded crops may germinate more quickly in warmer soils

MarketsFarm — If there could be one benefit to the excessive moisture across much of southern Manitoba and the Interlake region, that would be a potentially reduced risk for insect pests, according to John Gavloski, entomologist for Manitoba Agriculture, Food and Resource Development. For example, Gavloski cited flea beetles, which could damage canola. “If [canola]


It might look bad, but there’s a pretty good chance those canola 
volunteers aren’t actually doing that much harm.

What to do with those yellow soybean fields?

Now is also the time to scout for Bertha armyworms and diamondback moth

That bright yellow volunteer canola in your soybeans might look worse than it really is — so before trying to control it, consider whether it makes economic sense. That’s the advice Tammy Jones, Manitoba Agriculture and Resource Development’s (MARD) weed specialist gave in an interview following a Crop Talk webinar July 15. (Jones’ last day

The province has urged canola growers in parts of the province to be on watch for diamondback moth larvae and pupae.

Heads-up on diamondback moth

Eastern Manitoba and the southern Interlake have been hot spots for the province’s diamondback moth trapping program this year

Canola growers in eastern Manitoba and the southern Interlake should be keeping an extra eye out for diamondback moth this year, experts have warned. Manitoba Agriculture and Resource Development has noted exponentially higher counts of diamondback moth in those areas, something provincial entomologist John Gavloski has linked to windy weather in June blowing adult moths

Flea beetle damage ‘moderate’ across Prairies so far

Levels in Manitoba hit thresholds for spraying, reseeding canola

MarketsFarm — Flea beetles, cutworms and diamondback moths are only a few of the pests Prairie farmers have to deal with — and this year, so far, damage from flea beetles and cutworms has varied, as have moth counts. “Flea beetles are common throughout the Prairies, everywhere we grow canola. We haven’t been able to

So far only six of 99 bertha traps indicate risk.

Trap counts in the black for bertha army worm, diamondback moth surge

Manitoba’s trap counts remained in the low risk classes until mid-July, when diamondback moth populations started to reach threshold in some fields

*[UPDATED: July 24, 2018] Anyone worried about bertha armyworm will welcome the provincial trap counts so far, but some farmers may be spraying for diamondback moth. Diamondback moth is the only one of the two to report threshold populations, according to both trap data and Manitoba Agriculture entomologist John Gavloski. Eighty-eight out of the province’s

Manitoba Insect & Disease Update for July 5

Thistle caterpillar has been noted in some soybean and sunflower fields. Some levels of diamondback moth larvae approaching threshold have been noted in some canola fields in the southwest. There have been additional reports of suspected Phytophthora root rot in soybean. Growers in the western part of Manitoba are considering whether or not to make a fungicide application for

Replacing insecticides with sex in pest control

Genetically engineered male moths prevent females from reproducing

Cornell University researchers are combining two biotechnologies to control diamondback moths with sex instead of insecticide. The pesky feeders on crucifer crops, including canola, mustards and vegetables, have developed resistance to many insecticides as well as Bt (Bacillus thuringiensis), a soil bacteria that has been genetically engineered into corn and cotton to help control such

Conditions as of August 4, 2015

Winter wheat and fall rye harvest is underway in Manitoba. Preliminary reports indicate winter wheat yields range from 60 to 85 bu/acre, with low levels of fusarium damaged kernels in harvested samples. There are also a few fields of spring wheat, barley and field peas harvested last week.

The modified moths can mate as well as any other but they only produce male offspring


Scientists in Britain say they have developed a way of genetically modifying and controlling an invasive species of moth that causes serious pest damage to cabbages, kale, canola and other similar crops worldwide. In what they said could be a pesticide-free and environmentally friendly way to control insect pests, the scientists, from the Oxford University
