The Canadian Bt Corn Trait Tables have been updated for March 2023. These tables include all registered Bt Corn Trait Packages and indicates which Bt proteins and herbicide tolerant traits they contain and pests they target. These tables also include known resistance status for each pest and Bt protein. English: Canadian Bt Corn Trait Table […]
This article shares the findings from a 2021 on-farm trial that compared fall cover crop termination with planting green. It was conducted near Hagersville, Ontario, as part of an Ontario Soil and Crop Improvement Association Tier Two project. Highlights To watch a short video with in-season footage from the trial, click below: Background Information on […]
Co-authored with Ken Janovicek and Dr. Dave Hooker, University of Guelph Highlights By now, you’ve likely heard the message from the long-term rotation trials at Ridgetown and Elora: winter wheat in rotation improves corn and soybean yields. But with greater revenue coming in during corn and soybean years, the real question is whether these yield […]
The value from manure comes in the nutrients provided along with other components that benefit soil health. Manure adds a layer of complexity to fertilizer management, but it also provides benefits to crops that commercial fertilizer on its own cannot provide. Research helps with understanding the principles of how nutrients behave in different environments and […]
Results from the 2022 Ontario trap sites participating in the Adult Corn Rootworm (CRW) Trap Monitoring Network have been summarized in the infographic below. A more detailed report for all trap sites across North America was prepared by Ashley Dean and Erin Hodgson at Iowa State University and myself at: 2022 Regional Corn Rootworm Monitoring […]
The 2022 Ontario Corn Committee (OCC) hybrid performance trials are now available at GoCorn.net (Link HERE). Over past decades, Ontario’s average corn yields have increased around 2 bu/ac/yr. Staying current with new and competitive yielding hybrids is important. A key benefit of OCC trials is the ability to compare a large number of hybrids. These […]
Simple Summary there is limited guidance for safe fertilizer rates for strip till – unlike 2”x2” planter banding, there are many different fertilizer placement options in strip till there is likely some tradeoff with fertilizer placement in strip till – placement closer to the seed likely improves starter fertilizer effect and fertilizer efficiency, but likely […]
Co-authored with Albert Tenuta, Field Crop Pathologist, OMAFRA. OMAFRA field crop specialists in collaboration with Grain Farmers of Ontario (GFO) and members of the Ontario Agri-Business Association (OABA) have completed the annual Ontario corn ear mould and DON mycotoxin survey. Corn ear moulds such as Gibberella and their corresponding mycotoxins occur every year in Ontario. […]
Simple Summary – Changes in fertilizer:corn price ratios (not fertilizer prices alone) change optimum P and K rates. Corn prices increasing with fertilizer prices can limit price ratio changes. – Significant price ratio changes are required to appreciably change optimum P and K rates. For instance, changing fertilizer:corn price ratio ($/lb-P:$/lb-corn) in a recent Ontario […]
Western bean cutworm (WBC) trap counts are starting to ramp up quickly, with a few traps catching around 200-300 moths this week. Fewer trap sites are reporting to the GLMPMN, but from the ones that are, moth activity is increasing in southern counties (Chatham-Kent to Haldimand-Norfolk to Huron, as well as Prince Edward County (Fig. […]
More growers are noticing northern corn leaf blight (NCLB) – the most common corn leaf disease in Ontario. A proactive and integrated approach to management will mitigate significant financial losses. The simple answer Regular scouting is the best way to identify increases in the severity of NCLB. Ontario research has shown that an effective fungicide […]
As corn approached VT stage, it is the ideal time to start putting up the corn rootworm sticky traps. We are asking everyone participating this year to monitor and change traps weekly, on approximately 7 day intervals, so that we can properly calculate the # of beetles per trap per day. It will also help […]
Nitrogen (N) dynamics are always complicated, but manure adds a few layers of complexity. Nitrogen availability is impacted by soil texture, soil moisture, organic matter levels in the soil, form of N applied and of course, the weather. An application of liquid finisher hog manure applied ahead of planting would be expected to provide about […]
Reports are coming in that black cutworm larvae are cutting corn and even soybeans. We don’t often see cutting in soybeans but two fields in Niagara region were reported today with significant stand loss and a variety of sizes of larvae (Figures 1 & 2). Fields not treated with an insecticide seed treatment or planted […]
Key links for the 2022 Corn Rootworm Trap Network: The 2022 CRW Trapping Instructions are available here, though the trapping methods are similar to last year in that trap sites are to be monitored weekly (in regular 7 day intervals) for 6 to 8 weeks. 4 traps are setup each week at each trap site.
