Environment Canada has issued frost advisories for most corn growing areas of the province for the nights of September 18 to 20 which are expected to be near or slightly below freezing (Figure 1). This is earlier than we typically observe first frosts, earlier than our long-term season end dates (Table 1) and much lower […]
With the first usher of cool fall weather this past week, there were frost warnings for parts of Northern Ontario. With the introduction of increasingly shorter maturity corn hybrids, there has been more corn grown in shorter season areas than what has been typical in the past, and also growers who may have recently started […]
Background There are various ways to count growth stages of corn plants throughout the season. We use methods such as leaf over and corn height to decide when to come into fields and apply post emergence herbicides. Though what is the best method to assess corn growth in later vegetative stages? This becomes challenging when […]
Key Points: Rotating out of corn is the most effective way to reduce populations of Bt-resistant corn rootworm. To replace silage corn for 2021, establish fall rye or winter triticale immediately after 2020 silage corn harvest. After the cereal silage comes off in mid-May, establish sorghum-sudangrass and take two cuts. An energy source will need […]
Scouting for corn rootworm injury is important to detect potential resistance to rootworm Bt traits and to plan management options for the next growing season. It is especially important to report any fields showing signs of suspected resistance to your corn agronomist and the provincial entomologist. Rootworm larvae feed below ground on corn roots from […]
Canadian Corn Pest Coalition News Release: Corn rootworm (CRW) has historically been one of the most important pests of corn in Canada and can cause extreme economic loss and increased management costs. High CRW pressure in Ontario in 2020 is challenging current Bt corn rootworm hybrids and several growers of Bt rootworm hybrids are reporting […]
Summary Pre Sidedress Nitrogen Test (PSNT) soil samples were collected from 94 sites across the province from June 8th to 10th, 2020 The average PSNT value was 14 ppm, slightly above the long-term average of 12 ppm. Optimal nitrogen (N) rates are a function of both soil N supply and yield. Consider both when determining […]
Some corn was planted around 10th of April. A much larger acreage got in between the 21st and 27th. The rest got in during the first part of May. Corn planted to date has gone in under very good soil conditions for the most part. The remainder of the corn will be likely planted after […]
In these uncertain times, farmers with grain still in the bin may be considering storing that grain a bit longer than they’d originally expected. If you are in that situation, there are a few steps to take which will help you store your grain long-term in good condition. ENSURE GRAIN IS DRY When it comes […]
With some out of the box thinking, Ken Hartemink, hog and cash crop producer from St. Thomas, Ontario has mounted a strip tiller to the back of his manure tanker for one-pass manure incorporation and seedbed prep for next year’s corn crop. Ken Hartemink is a hog and cash crop producer just outside St. […]
Farmers who may be struggling to get corn dried this year are looking for alternate options. It is possible to use natural (unheated) air to dry the corn. Natural air drying is gentle and does not require any specialized equipment, other than a grain bin with a reasonably-sized fan, and maybe a small heater. However, […]
Many grain farmers may have questions about storing and drying corn this year, with recent propane shortages and a lot of wet corn still in the field. Decisions for harvesting corn will vary from farm to farm based on local conditions and factors (corn moisture, distance to alternative dryers, crop standability). Some farmers may already […]
So your corn was planted late and got damaged by frost, or maybe it wasn’t quite fully mature when you harvested. You ended up harvesting low-test-weight corn. Now it needs to be dried and stored. Storing in your own bins may provide some marketing advantages. There may not be much tolerance for lower-quality grain sold […]
Late planting combined with below-average heat unit accumulation this year means Ontario’s corn crop is behind in maturity from where we would normally expect it to be. Autumn is here in full swing and many parts of the province have already experienced frost. If corn is not fully mature by the time the first frost […]
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 Provincial corn ear mould and mycotoxin survey. Corn ear moulds such as Gibberella and their corresponding mycotoxins occur every year in Ontario. […]
