There are exceptions, but most insecticides are neurotoxins designed to target an insects’ nervous systems.

Resistance, Group 4 and neonicotinoids

Saskatchewan pest management specialist updates growers at CropSphere

Saskatchewan’s provincial pest management specialist updated growers on the current state of government regulation of neonicotinoids at CropSphere in Saskatoon in January. He began with a review of insecticide modes of action.

Saskatchewan bugs to watch for in 2019

Low survey results in 2018 could be good news for Saskatchewan farmers this season

The 2018 pest survey results for Saskatchewan look like good news for the 2019 season. Grasshopper, pea leaf weevil and diamondback moth populations were all low in 2018.

Wireworms are the larval stage of the click beetle.

Wireworm populations on the rise

Wireworms are a growing concern for the potato industry. Creative controls are needed


Wireworm populations appear to be on the rise in Western Canada. Wireworm, which is the larval stage of the adult click beetle, affects many crops, including cereals and pulses, but they are particularly damaging to potatoes. Holes created by wireworms can render tubers unmarketable and serve as points of entry for potato pathogens. This pest has […] Read more


Implementing strategies to stave off herbicide resistance can bring increased costs 
to individual farmers in the short term, while the economic benefits are delayed.

Managing herbicide resistance costs

Farmers considering herbicide resistance strategies are looking at the economics first

There are several reasons many farmers haven’t yet adopted herbicide resistance management (HRM) plans. These include a lack of information, the complexity of different management strategies and limited time. But a major reason is still economics. Many farmers worry about the costs of implementing a resistance management plan, especially if they’re uncertain about the potential […] Read more

On the farm: the 2016 crop year in review

Every year is different on Kevin Elmy's farm. This year: cover crops, soybeans and rain

The good thing about farming is two years are rarely alike. 2016 started out a bit on the dry side, with close to ideal subsoil moisture. The occasional May shower did not delay seeding much. About 20 per cent of our acres were seeded in the fall of 2015 to Luoma winter triticale, which helped reduce the spring […] Read more


Cleavers can be tricky because they are both a spring and winter annual.

Timing is key to whipping weeds

It’s easiest to kill weeds when they’re actively growing. Make sure you know when that is

Whether you’re telling a joke or treating a weed, timing is critical. And as anyone who has failed at weed control will confirm, it’s no laughing matter. Once you let weeds gain a foothold they can soon get out of hand, so it’s crucial to identify the life cycle of the weeds in your field […] Read more

Controlling bugs with seed treatments

Technology has given western Canadian farmers access to a wide range of options when it comes to insect control in canola. Crucifer and striped flea beetles, wireworm, cutworm, root maggot, cabbage seedpod weevil, bertha armyworm and diamondback moth are just some insect pests that can be particularly problematic for both crop health and farmers’ bottom […] Read more
