Is rotating your herbicides enough?

Integrated weed management can slow herbicide resistance, but rotation is just one piece

By
Integrated weed management (IWM) is not rotating herbicides or modes of action. IWM is combining one of more different weed management techniques, such as chemical, cultural, physical or biological weed control. Some IWM methods are easy to implement, such as making sure you select good, certified seed that will grow vigorously and out-compete weeds. Seeding […] Read more
Biologists isolate novel genes from cauliflower to improve crop nutritional value. A study committee of the National Academies of Sciences, Engineering and Medicine looking at gene-altered crops notes a genetically engineered characteristic that alters the nutritional content of a crop is “unlikely to have the same environmental or economic effects as a characteristic for herbicide resistance.” (Peggy Greb photo courtesy ARS/USDA)

U.S. study finds no risks to people, planet in GMOs

By ,
It’s time for the task of regulating new crop varieties to focus on plants’ characteristics rather than on how the plants were developed, a team of U.S. scientists recommends in a new report. A study committee of the National Academies of Sciences, Engineering and Medicine on Tuesday released an “extensive” study of genetically engineered crops, finding […] Read more

What to watch for in young corn

A strong start to your corn crop will ensure you a rewarding harvest

By
The first step in guaranteeing a profitable harvest is ensuring corn plants are thriving in the early stages of growth. At the planting to seedling stage, corn is most susceptible to seed and root rot diseases. Disease such as seedling blight, and root rots caused by pythium, fusarium or rhizoctonia could affect seedlings, particularly in […] Read more

Slow resistance with layered herbicides

Gowan representatives say layering isn't just about dressing for fickle weather anymore

By
Layering herbicides is a way to manage or delay herbicide resistance on the farm. The key is to apply a residual before seeding. The residual creates a herbicide layer in the soil. That layer kills weeds as they try to push emerge. With fewer weeds, there is less selection pressure on herbicides used later in […] Read more

Controlling seeds post-harvest

Can pulverizing weed seeds after harvest control weeds in Western Canada?

By
As buzz builds about Australia’s Harrington Seed Destructor, researchers are looking at whether pulverizing seeds after harvest will work on the Prairies. But preliminary research shows post-harvest seed control is unlikely to work for all of Western Canada’s weeds. Breanne Tidemann presented new research at the Herbicide Resistance Summit in Saskatoon this March. Tidemann, who is […] Read more

VIDEO: Herbicide resistance spreading in Western Canada

From the International Weed Resistance Summit

By
At the Herbicide Resistance Summit this past March, Dr. Hugh Beckie presented the results of the latest weed survey in Saskatchewan. Agriculture and Agri-Food Canada researchers hadn’t finished screening for herbicide resistance. But Beckie expects to see herbicide-resistant weeds on over 50 per cent of cultivated land in Saskatchewan, he told Grainews reporter Lisa Guenther. […] Read more

Early season weed control is key

Spring spraying can be challenging. Look for the right weather and moisture conditions

By
Early season weed control is a top priority for canola growers. Weeds that emerge before the crop are much more competitive than those coming up with the crop, and herbicide can’t undo the damage done by weeds left uncontrolled before emergence. Clark Brenzil, provincial weed specialist with the Saskatchewan Ministry of Agriculture, says research shows […] Read more

What’s it take to produce new pesticides?

Farmers know a lot about using pesticides. Here’s a chance to learn about how chemical companies dream them up, produce them and market them to you

By
Have you ever wondered how chemical companies create and launch new pesticides? How much it costs them, how they decide what it will cost you and how they come up with those names? Well, we were wondering the same thing at Grainews, so we talked to Kelly Bennett. Bennett manages Dow AgroSciences’ cereal broadleaf herbicides […] Read more

Look out for the Devil’s trumpet

Jimsonweed, also known as Devil’s trumpet is a highly toxic weed

By
According to provincial weed specialists in Alberta, jimsonweed, a highly toxic and problematic weed species, was found in three Alberta canola fields (Barrhead, Leduc and Westlock) last month. Growers are currently working with their provincial departments and the CFIA on an eradication strategy, although they are not considering it a major problem at this moment. […] Read more

Crop Advisor’s Casebook: Puzzling patterns in a pea field

A Crop Advisor's Solution from the October 21, 2014 issue of Grainews

By
Back in late spring, Allan was alarmed to see some strange patterns showing up in his crop of field peas at his 2,000-acre mixed grain farm near Aylsham, Sask. Irregular sections of pale green peas were appearing in the field, in contrast to the lush green growth of the rest of the crop. The pea […] Read more
