Ontario Corn Planting Mostly Complete; Soybeans Over Half Finished

Most of the corn is now planted in Ontario, while over half of the soybeans are also in the ground, according to the latest weekly provincial crop report on Thursday.

Meanwhile, winter wheat crop injury from last week’s cold snap was less severe than anticipated, although concern remains for wheat crops that have generally shown little growth and development over the last six weeks due to colder-than-normal weather.

Temperatures over the past week have been significantly warmer than the week prior. Most of the province saw rain over the long weekend. In many areas this was welcome news, but much of southwestern Ontario received significant downpours and flooded fields were a common sight.


Most of the intended acreage was planted before the recent rains. The remaining unplanted acreage is primarily in regions with heavy clay soils, or lighter soils where growers halted planting prior to last week’s cold temperatures to avoid cold injury risks. After being underground for several weeks due to the cool weather conditions, early planted corn is starting to emerge in the southwest. Central and eastern Ontario should see emergence starting this week.


Soybean planting continues, but the range of progress across regions of the province varies widely (25-80%). The average for soybean acreage planted in the province stands at around 60% complete.


Concerns of crop injury from last week’s cold snap was less severe than anticipated. However, concerns over crop health exists in areas where there has been very little growth and development over the last 6 weeks due to the cold temperatures. As temperatures continue to climb, it is expected that those plants will begin to grow more rapidly and look better. Winter wheat in southwestern Ontario is at flag leaf, while most of the rest of the province is at or approaching stem elongation.

Spring cereals continue to emerge with most of the crop being at the 2-3 leaf stage. Weed control continues in these fields. With the warmer temperatures forecasted, it is expected that weeds and cereal crops will start to grow more rapidly.


Like wheat, forages seem to have made it through the cold relatively well. The exceptions are mostly in fields that were cut or grazed late last fall. Alfalfa plants are weakened by late cutting, and spring conditions may not have allowed sufficient recovery for them to withstand the frost.


Winter canola fields in Essex and Chatham-Kent are at or near white mold fungicide application timing and are fully in bloom. Other fields that are further north are a week or more from fungicide timing. So far, no insect pests have been observed in winter canola. Spring canola planting is wrapping up and seedlings are emerging.
