How potato pests find ways around insecticides

Resistance to insecticides is complicating pest control, prompting experts to advocate for integrated management strategies

Several mechanisms allow insects to survive pesticide applications — for example, metabolic resistance, in which the pest detoxifies the insecticide faster than a susceptible individual, or target-site resistance, in which the receptor sites affected by the pesticide are altered.

New Group 14 tank mix partner may be on horizon

A Japanese firm’s new chemical isn’t like the other PPO inhibitors

Not yet registered in either Canada or the U.S., the Japanese active ingredient-in-waiting could be needed sooner than later, because many growers in Saskatchewan and Alberta are struggling with herbicide-resistant kochia.

Red clover: A forage crop worth a second look

Cool-season adaptability, strong yields and soil benefits may make it an attractive choice

Red clover is a cool-weather crop. While alfalfa tends to yield better in southern regions, the trend shifts as you move north. Wisconsin forage expert Dan Undersander points out that this shift is noticeable even within his own state.

Cutting the nitrous oxide emissions without losing yields

Better nitrogen management promises to both protect crop yields and reduce greenhouse gas emissions from fertilizer; new research looks to verify how much difference it actually makes

Grow forages, starve weeds

Forages disrupt weed routines and slow herbicide resistance — if you can use them

“Forages actually can be used to combat resistant weeds,” Kim Brown says. “A perennial forage stand will last for several years, but in a spring annual crop rotation, you’re dealing almost exclusively with annual crops most of the time.”

Concerned over canola? Focus on agronomy

In a stressful market environment, best practices can reduce risk and drive profit

The best option for canola producers in the current market environment may be to apply agronomy practices that can improve profits for little to no added cost, the Canola Council of Canada says.

Farmers can now choose between multiple track and tire technologies that help reduce the compaction risks around supersized grain carts.

Supersized grain carts a weighty problem

They can boost harvest efficiencies, but also ramp up risk of serious soil compaction. Here are some tips to reduce that risk

Grain carts can still cause serious soil compaction whether they’re on tracks or wheels, but Scott Shearer’s research at Ohio State indicates less of a yield hit with tracks compared to wheels in unfavourable soil conditions. Here are some tips to reduce compaction risk.
