Jim Tansey and Keith Gabert talk about flea beetles – including how far they travel to find the first canola crops, major differences between striped and crucifer species, and how long the risk can last…

Striped flea beetles tend to emerge earlier than crucifer flea beetles, and some are already feeding on canola volunteers. Are first-emerging crops at higher risk?… -
Respirators for pesticide applicators are NIOSH/MSHA/BHSE approved organic-vapour-removing cartridge with a pre-filter approved for pesticides or a NIOSH/MSHA/BHSE approved canister for pesticides…

A full-fledged bertha armyworm outbreak continues in the Peace region. Continue scouting, noting that fields at thresholds can be right beside fields with low counts…

Bertha armyworm numbers are at thresholds in more Peace-region canola fields this week. Growers in the Birch Hills, Saddle Hills and Northern Sunrise areas in particular are encouraged to scout… -
As predicted by moth traps, the Peace region has fields at thresholds. Beyond there, a few field here and there across the Prairies have been sprayed but the worm is not a problem on most fields…

The bertha armyworm risk is fairly low across most of the Prairies, but the insect pest is at high numbers in localized areas. These infestations can occur even when adult traps in the area had counts within the ‘low’ risk range, so scouting is recommended everywhere… -
Insect pressure is low, for the most part. Localized outbreaks of bertha armyworm and other insects could be found, so scouting is still important, but no insect is causing any major damage at this time…
