Corn School: Understanding 30 years of rising yields
Ontario will set a new corn yield record in 2017 with the crop expected to hit an average of 180 bu/ac or better. Where is all that yield coming from? Corn physiologist Dr. Thijs Tollenaar has poured over the data and identified three key factors driving corn yield improvement. A long-time University of Guelph professor… Read more »
Corn School: Evaluating late-season northern corn leaf blight control
With late planting and slow maturity, much of Ontario’s corn crop may be in for a challenge as leaf diseases arrive in fields across the province. In this episode of RealAgriculture Corn School, we catch up with Ontario Ministry of Agriculture, Rood and Rural Affairs (OMAFRA) field pathologist Albert Tenuta in his leaf disease nursery… Read more »
Corn School: Could 2017 be another vomitoxin year?
A late-maturing crop, difficult environmental conditions, significant insect pressure and potential for late-season leaf disease…although too early to tell – this growing list of factors could lead to another year of high vomitoxin levels in the Ontario corn crop. In this episode of RealAgriculture Corn School, OMAFRA plant pathologist Albert Tenuta takes a look at the… Read more »
Corn School: Managing western bean cutworm
It’s lining up to be a big corn pest year and the insect to watch for in the weeks ahead is western bean cutworm (WBC). In this edition of RealAgriculture Corn School, OMAFRA entomologist Tracey Baute explains that late planting across Ontario has left the young corn crop more susceptible to an increased number of… Read more »

Corn School: Leaf Blight Defence Starts With Genetics
Choosing the right genetics is the most important decision growers make when tackling leaf diseases such as northern corn leaf blight (NCLB). Fungicides applied in-season can provide both curative and preventative benefits, but the battle to fend off yield-robbing leaf diseases starts with your seed choice explains, OMAFRA field pathologist Albert Tenuta. In this episode… Read more »
Corn School: Harvest Quickly to Fend off Steep Downgrades
Ontario’s corn crop is showing high vomitoxin levels and growers are being urged to harvest as quickly as possible to preserve corn quality. Last week, the OMAFRA Field Crops team revealed that 26% of the samples taken in its annual vomitoxin survey had DON concentrations of 2.0 ppm or greater. At these levels, vomitoxin produced… Read more »
