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 at harvest, since everyone is…
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 hits, frost damage can occur. …
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. These mycotoxins, particularly deoxynivalenol (DON, or…
Late planting dates, low Crop Heat Unit (CHU) accumulations, and early frost may result in situations where corn is killed by frost before it reaches the normal stage of maturity and moisture for silage. Some fields planted for grain may not mature adequately for optimum yield, moisture and quality. Farmers may be looking at salvaging these crops by harvesting or…
Will My Late Planted Corn Mature Prior to a Frost? Spring of 2019 was clearly frustrating to be a corn grower. Frequent rains and cool weather delayed planting for large parts of Ontario. A significant amount of corn was planted into June (Figure 1.), and many fields tasseled in early to mid-August, later then the middle to late July we…
Winter Wheat Winter wheat harvest is winding down across the province and reported yields to date have ranged from 80-130 bu/ac which compares well to the five-year average yield of 82.7 bushels/ac. This was a pleasant surprise for many growers’ considering all the stresses the winter wheat crop had to endure. Good reports of straw yield averaging 4000 pounds per…
Usually by this time in July, I am writing about how we are approaching peak flight for WBC in at least the southwestern counties. But with the delay in growing degree days this year, we have just caught the first WBC moth in Ontario this week, a month later than usual start catching them. Despite the late WBC activity, we…
Summary The Pre Sidedress Nitrogen Test (PSNT) soil samples were collected from 66 different sites across the province between June 17th and 19th, 2019 The average PSNT value was 8.3 ppm, which is below the long-term average of 12 ppm Consider corn stage and yield expectation along with PSNT values when determining nitrogen rate requirements in 2019. Below normal soil…
It’s that kind of year. Expect the unexpected or at least don’t be surprised when something doesn’t follow the rules. It’s a wet year. That usually makes us more disease prone than insect prone. And entomopathogens (fungus that kills insects) usually kick in. But we are also dealing with very delayed planting with small plants emerging, and lack of timely…
Over the last few years a number of corn insect pest populations have developed resistance to at least one Bt trait used in corn hybrids. From western bean cutworm (WBC) resistance to Cry1F, corn earworm (CEW) resistance reported to Cry1Ab, Cry1A.105 and Cry2Ab2, to the latest confirmation of European corn borer (ECB) resistance to Cry1F in the Maritimes. Although companies…
Corn Significant planting progress was made the end of last week and through the weekend as sunshine and warm temperatures dominated for a string of days. Despite the calendar date and reduced yield potential of later planting, many continued to plant corn noting the competitiveness of returns relative to soybeans. Many areas are reporting corn planting reaching 90-95% of intended…
Corn Progress was made over the last week in areas with lighter textured soils. Those areas now have upwards of 80% of their intended corn acres planted. However, regions with heavier textured soils such as Lambton, Essex, Niagara and Middlesex have 30% of their corn acres planted. Overall, ~60% of the intended corn acres are planted in the province. With…
It seems a bit cruel to point out some potential pest issues in a season like we have had where few crops are even in and might not even get in. But some crops are in the ground and at risk. There are a few pests that will take advantage of delayed crop emergence or be so limited in what…
Planting progress remains slow for all crops, and spray applications have also been significantly delayed by poor weather. Temperatures forecasted for early June are relatively cool, remaining around or below the 20°C mark in many regions. Corn Corn planting progress at the end of May was estimated to be less than 50% complete. In some regions, corn planting at the…
Weather patterns have been variable, leading to regional differences in progress on planting and crop growth. Soils continue to remain unfit for field operations in large parts of the province, especially in much of the southwest and parts of eastern Ontario (figure 1). A few pockets have had windows of opportunity to catch up on cultivation, fertilizer spreading, and planting….
