Integrated weed management requires as many weed control methods as possible. You try to prevent weeds from becoming established. Weeds can be controlled with tillage. Cultural weed control can be used by making your crop as competitive as possible. Biological weed control utilizes organisms that may be pathogens that kill the weeds. Rodents and insects eat weed seeds in your crop and can have a huge effect. Integrated weed management includes herbicides as well.

There are now 41 glyphosate-resistant weeds in the world. Seventeen of those occur in the United States. There are six species in Canada, and four of those occur in Ontario. In Ontario, glyphosate-resistant giant ragweed was confirmed in 2008, Canada fleabane in 2010, common ragweed in 2011 and waterhemp in 2014.

According to David Lobb, best management practices for soil health might actually have a negative impact on water quality, because any extra phosphorus stored in residue on the soil surface can potentially move into waterways in runoff events.

Research is building on the many benefits of cover crops, from their ability to help boost yields in subsequent crops to improved soil structure and reduced erosion.

Health Canada has announced its plan to phase out most uses of the neonicotinoids clothianidin and thiamethoxam, citing that the two insecticides are being measured at levels harmful to aquatic insects.

With high canola prices relative to other commodities, the temptation to run continuous canola is high. But does it really pay in the short term? A research study shows that net returns aren’t necessarily better, and that insect and disease pressures increase over time.

While most producers are wrapping up planting this spring, the Top Crop Manager team has soil on the mind. We’ve spent much of the very long winter and even shorter spring season planning our 2019 Soil Management and Sustainability Summit (to be held Feb. 26, 2019 in Saskatoon, and March 11, 2019 in Ottawa – check out www.topcropsummit.com for more details).

The Canadian Agricultural Partnership was launched April 1, with the intent to chart the course for government investments in the sector over the next five years. The partnership aims to continue to help the sector grow trade, advance innovation while maintaining and strengthening public confidence in the food system, and increase its diversity, according to a press release from Agriculture and Agri-Food Canada.

Cutworms are present across the Prairies, and in some years some species of cutworms can reach levels that are of economic concern in field crops. The focus of a five-year project conducted across the Prairies resulted in the development of better identification tools, a better understanding of cutworm biology and their natural enemies, and a management guide to improve cutworm monitoring and control in different crops.

In Western Canada, wild oat continues to be one of the most problematic weeds. As part of an integrated weed management strategy, researchers continue to look for additional options and different lifecycle timings to reduce populations, frequencies and herbicide resistant populations.

While putting his issue together, I was reminded just  how intricate (and complicated) disease is. Let’s look at Fusarium head blight (FHB) and its many forms as an example.

Last April, Real Agriculture agronomist Peter Johnson tweeted a photo of winter wheat seedlings surrounded by a tangle of chickweed. “Chickweed in wheat needs to be controlled in fall! Shepherds purse, stinkweed same. Too much spring competition!” he wrote.

This is important information for irrigation farmers to decide when to irrigate, but it’s equally important for dryland farmers to understand their soil moisture conditions when deciding on crop input requirements.

Some Prairie farmers were fortunate enough to have good moisture conditions to band anhydrous ammonia or urea last fall to get a jump on spring seeding. But for the majority of farmers, dry conditions in many parts of the Prairies may mean adjustments to nitrogen (N) applications.
From humble beginnings, soybean acreage hit 2.3 million seeded acres in Manitoba in 2017. Can those acres be sustained? The answer lies with managing glyphosate resistance.

Reducing natural habitats in order to create more acres of farmland may become a regretful practice with negative consequences – including reducing the yield potential of canola and other oilseeds, says Melanie Dubois, research scientist with Agriculture and Agri-Food Canada (AAFC) from the Brandon, Man., Research and Development Centre. Dubois recently finished her second field season of a three-year project.

A seed treatment is a vital and effective product, so long as it stays on the seeds where it can do its work. When it is released into the surrounding environment, however, it can cause significant political and environmental concern.
