Should you go ground or air? That’s the question many growers struggle with as they try to determine the best method of applying disease-fighting fungicide to their growing corn crops. On this episode of RealAgriculture Corn School we tackle that question with two of North America’s leading plant pathologists — University of Kentucky’s Kiersten Wise… Read More
Strip tillage for corn continues to gain momentum as more growers cultivate strips to reduce total tillage and place seed and fertilizer in soil that warms faster prior to planting. But what about weed control? How do growers keep yield-robbing weeds at bay in these cultivated strips and optimize the potential of the growing environment… Read More
It’s mid-April and the weeds are growing in eastern Canada. Overall, good weather has many fields one month ahead of schedule, and in some cases, two months ahead of backward 2019 spring conditions, notes BASF agronomist Rob Miller. That means it’s time for growers to tackle perennial weeds and winter annuals like Canada fleabane before… Read More
First there were strobilurins, then came triazoles, and now we have succinate dehydrogenase inhibitors or SDHIs. That can be a bit of tongue twister, but it also adds up to three classes of fungicides and multiple modes of action that more growers are stacking up to bring stronger disease protection to their cornfields. That’s the… Read More
Tar spot, a new corn leaf disease, has moved through the U.S. Midwest, into Michigan and Wisconsin, and now sits at the doorstep of Ontario’s corn growing region. Characterized by tar-like speckling on the upper surface of corn leaves, the fungal pathogen has been delivering yield hits ranging from 20 to 60 bushels per acre… Read More
Corn growers in the mid-south and Midwest U.S. are being asked to take a closer look at diseased corn leaves as re-emerging diplodia leaf streak pushes into major corn growing states. The disease looks very similar to northern corn leaf blight (NCLB), a leaf disease Canadian growers typically identify based on its characteristic cigar-shaped lesions…. Read More
Changing weather patterns played havoc with corn planting and harvest in 2019 and they also affected insect cycles and how pests impacted the crop. Ontario Ministry of Agriculture, Food and Rural Affairs entomologist Tracey Baute notes that the cold, wet spring had a big impact on western bean cutworm (WBC). A significant reduction in early-season… Read More
The good news is tar spot — a new corn leaf disease — has yet to be found in Ontario cornfields. The bad news is it’s only a matter of time before the yield robber is confirmed in the province, says Ontario Ministry of Agriculture, Food and Rural Affairs plant pathologist Albert Tenuta. On this episode… Read More
Testing for DON in Ontario’s 2018 corn crop was an incredibly frustrating process for growers. With gibberella ear rot infecting a wide swath of corn in the province, many growers were exasperated when samples from the same load of corn taken from a field would show wide variation in DON levels — sometimes from 3… Read More
One of the big questions surrounding the Ontario corn crop of 2019 is whether plant roots can push through tough planting conditions and continue to feed the plant throughout the growing season. On this episode of the RealAgriculture Corn School, agronomist Peter Johnson takes a look at the challenges root systems faced in one of… Read More
Western bean cutworm (WBC) moths typically hit peak flight this week in Ontario — but not this year. Cold, wet spring conditions across the province not only delayed crop planting and development but also put the squeeze on the mating and flight patterns of the yield-robbing pest. On this episode of RealAgriculture’s Corn School, Ontario… Read More
Difficult planting conditions across Ontario this spring are set to test growers yet again as corn fungicide application timing approaches. On this episode of the RealAgriculture Corn School, Ridgetown College, University of Guelph professor Dave Hooker explains that growers looking to control gibberella ear rot can expect a 50 per cent reduction in DON when… Read More
Challenging Ontario planting conditions may follow the corn crop through the entire season and cause 2019 harvest disease headaches for growers. That’s the message Ontario Ministry of Agriculture, Food and Rural Affairs’s plant pathologist Albert Tenuta shared with growers attending a Huron Tractor combine clinic last week at company headquarters at Exeter, Ont. With corn… Read More
A tough fall, winterkill, and a cool, wet spring are adding up to a condensed and busy herbicide application window for growers across Ontario.One of the first challenges is how to manage best all the abandoned winter wheat acres that are likely to be planted as corn or soybeans. On this episode of the RealAgriculture… Read More
For people who play the stock market, an opportunity to cash in on an 826 per cent return on investment doesn’t come along too often. But Ontario farmers can realize this type of return every time they apply herbicide in corn fields that experience intense weed pressure, says University of Guelph weed scientist Dr. Peter… Read More
