MarketsFarm – Although it’s still early in the growing season, some insect pests have already posed a threat to crops in Saskatchewan or could do so in the near future, according to James Tansey, provincial specialist for insects/invertebrate pest management. Among the pests he cited were grasshoppers, flea beetles and pea leaf weevils. Tansey said […] Read more

Insects posing problems in Saskatchewan crops
Grasshopper, flea beetle damage already reported
Best to be scouting for insect pests
'Definitely' watch canola for flea beetles
MarketsFarm — Although it is still relatively early in the crop year, Manitoba entomologist John Gavloski strongly advises farmers to carefully watch their fields for any signs of insect pests. Gavloski couldn’t say for sure if insect damage was going to be bad this year but based on what’s transpired over the last three years, […] Read more
Matador, Voliam insecticides back in ‘limited’ release
Revised labels prohibit feeding, foraging of treated crops
Syngenta Canada no longer plans to keep its lambda-cyhalothrin insecticide products off the market in Western Canada this year — but it’s planning to have a smaller supply. The crop chem and seed company announced Friday it will have a “limited amount” of its lambda-cy-based products Matador 120EC and Voliam Xpress available in the West […] Read more
French agency drops fumigant ban on non-EU grain exports
Limit on phosphine won't apply if use required for export
Paris | Reuters — French health safety agency ANSES on Thursday cleared the use of phosphine pesticide in contact with grains exported outside the European Union when importing countries require the process, averting a halt to shipments from the EU’s top grain exporter. In late October ANSES cleared the use of phosphine tablets used for […] Read more
France says pesticide ban will not hit grain exports
Fumigant can't be in 'direct contact' with grains
Paris | Reuters — France will ensure that a decision by health and safety agency ANSES to ban the use of a pesticide in direct contact with grains does not hamper its exports outside the European Union, its trade and agriculture ministers told Parliament on Tuesday. In late October ANSES cleared the use of phosphine […] Read more
Controlling insect pests without harming beneficial insect species
Science Notes: Horizontally transferred genes in insect genomes can selectively kill green peach aphids
Killing crop-damaging insects by targeting genes essential to their survival is a promising approach to pest control. Because essential genes are often conserved across multiple insect species, the challenge is finding targets whose silencing kills the pests but not beneficial insects. Led by Georg Jander, a professor at the Boyce Thompson Institute (BTI), a team of […] Read more
Insecticide restriction pushes growers to older chemistries
PMRA limits use of lambda-cyhalothrin
The Pest Management Regulatory Agency has applied restrictions to insecticides containing the active ingredient lambda-cyhalothrin. Among other changes, it can no longer be applied on crops destined for use as animal feed. The restriction means growers who previously used products such as Matador, Warrior, Silencer, Labamba, Voliam Xpress and Endigo will have to find other […] Read more
Canola growers face potential new pests and insecticide loss
Scouting and biosecurity diligence could provide some protection
Swede midge pressure may have decreased during the 2022 canola season, but new pest threats are on the horizon. The pollen beetle, a European pest established in the Maritimes and Quebec, is creating concerns as researchers watch the Northern Ontario-Quebec border. “It does cause significant damages to canola when the beetle larva feed inside the […] Read more
Ontario confirms canola flower midge populations
New midge species could be native to North America
The emergence of a new canola gall midge in Ontario in 2021 has prompted researchers to re-assess swede midge data. The canola flower midge (CFM) was first noted in Western Canada in 2016. Researchers saw a significant number of midges bypass pheromone lures but also saw distinct canola gall injury. It was not the damage […] Read more
French insect-based ingredients maker Ynsect to expand in North America
U.S. plant would use Ardent Mills' flour milling byproducts
Paris | Reuters — French company Ynsect said on Tuesday it had signed deals to build insect ingredient production sites in the United States and in Mexico as the firm kicks off what it says will be the world’s largest insect farm. Ynsect breeds mealworms that produce proteins for aquaculture, livestock, pet food, fertilizers and […] Read more
