Herbicide resistant weeds in all crops are a continuous concern, and for corn, these can be reduced with effective management practices. “The whole strategy [of weed control] is going to revolve around prevention, through rotation, tillage – or lack thereof – and soil applied, or pre-plant herbicides, followed with scouting for escapes,” says Craig Reid, […] Read more

Managing herbicide-resistant weeds in corn
Planning and variety in rotations is a large factor, but cover crops and herbicide programs help too
‘Stacking’ of row-crop tillage shows promise
Three modes of action monitored in organic crop study
Using the same terminology employed by agrochemical manufacturers promoting the “stacking” of herbicide-resistant traits in seed, an organic-sector specialist from the University of Maine sees promise in multiple modes of mechanical weed control. Eric Gallandt spoke on integrated weed management at the Guelph Organic Conference. He is one of the co-originators, along with Iowa State […] Read more
Can drones replace self-propelled spraying equipment?
Drones can help improve product application and provide better results
Drones are quickly becoming a preferred tool for growers across the globe. Some drones offer high-concentration, small-volume spraying technology with the same efficacy of coverage as typical agricultural equipment, allowing producers to use less product. As well, the flight ability and down-facing fan action allow growers to ensure timely applications independent of soil conditions, with […] Read more
Weeds may compound effects of climate change impact
Study says corn yields are expected to be reduced as weeds compete for fewer water resources in the American Midwest
Glacier FarmMedia – A U.S. study has found that weeds will likely deepen the negative impact of climate change on corn yields, says a scientist. Such results likely extend to other crops, said Marty Williams, an ecologist with the U.S. Department of Agriculture. “I think what this tells farmers is that going forward, more than […] Read more
There’s foreign workers in the bug world, too — and they attack weeds
Bringing in weed-attacking pests is a laborious process but it’s often the only option for pastures
Glacier FarmMedia – There are many ways to control weeds. Rose De Clerck-Floate’s favourite is to reunite them with their long-time enemies from the old country. “All of the weeds here can come from other parts of the world, mostly Europe and some from Asia, and establish here without the organisms that keep them in […] Read more
Shocking weeds into submission
The Weed Zapper uses electricity to mortally injure weeds
Controlling weeds can be a tough challenge for organic growers with few chemical options, and also for conventional growers battling herbicide-resistant weeds. For this reason, mechanical weed control has been making a comeback and innovators are now offering more options. One such option is the Weed Zapper, which uses electricity to kill weeds and does […] Read more
Covering up weed seeds
Input savings, soil health are among the benefits of cover crops
Cover crops are not free, but they don’t have to be a cost. In fact, they can save farmers money. Researchers and farmers talked about the benefits during a recent session hosted by the Ontario Soil and Crop Improvement Association. While there is always variability, weed suppression and population reduction are the chief – though […] Read more
VIDEO: Water hemp weed management
Field Talk with Chris Snip
In this edition of Field Talk, Farmtario contributor Matt McIntosh talks with Chris Snip, crop sales specialist with Agris Co-operative, about waterhemp in Essex County, wider herbicide management concerns – and the importance of dialogue with your farm neighbours.
Grassy weeds in winter wheat at harvest
OMAFRA Field Crop Report for July 28
Three different types of grassy weeds have been found above the winter wheat canopy at harvest this year. To prevent them from becoming a problem, they need to be identified so that the appropriate management actions can be taken. Here is a breakdown of each grass species and control options. Chess grass (Bromus secalinus) Management: Chess grass […] Read more
Weed of the week: Lamb’s quarters
It’s important to get ahead of this prolific, early-growing species
Lamb’s quarters can be a real contender in the field despite susceptibility to a variety of active ingredients. A species of the goosefoot family, lamb’s quarters (Chenopodium album L) require early and active management. Why it matters: Lamb’s quarters are extremely common, emerge early and can significantly reduce yields. Lamb’s quarters are a summer annual […] Read more
