Field Crop News

Field Crop News is an archive of information dedicated to the production of over 8.5 million acres of field crops in Ontario and a forum for which producers, researchers and industry personnel can share information and ideas. The crop technology team with the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA), faculty at the University of Guelph and Ontario field crop producers continually work together to find ways to improve field crop production. The key learning and outcomes from these collaborations are captured at “Field Crop News”.

Fall Weed Management Tips Many farmers have witnessed the value in applying herbicides in the fall to perennial weeds, especially perennial sow-thistle and dandelion (Figure 1.). Often they will see a reduction in their population the next year as well as a delay in their shoot emergence. This allows the planted crop to have a competitive advantage over those perennial...

Making Soybean Silage

Thursday, September 21, 2017

Co-author: Horst Bohner In 2017, wet growing conditions have made it difficult to put up high quality forages. A wet spring delayed planting in many regions, and the cool summer and an early frost may prevent some soybeans from reaching their full potential as an oilseed crop. These circumstances may encourage producers to consider harvesting soybeans for silage. Before committing...

Best Management Practices for Late Planted Winter Wheat With many soybean fields across the countryside just starting to change colour, harvest is not likely to begin anytime soon.  A cool, wet spring delayed soybean planting in much of the province and cooler temperatures in August and September have pushed harvest back this fall compared to the last two years.  As...

Gauging Corn Growth Stage for Frost Risks With a later than normal planting window and a summer growing season seemingly short on summer weather, some growers have been monitoring their corn growth stages and asking about gauging the risks associated with corn maturity and frost, particularly those who planted very late or have longer maturity hybrids. While there are still...

Soil fertility benefits of wheat in rotation

Tuesday, September 05, 2017

Before long, the 2018 winter wheat crop will be seeded across the province (Figure 1). Long-term research at the University of Guelph’s Ridgetown campus shows that winter wheat in rotation provides an additional 10 bushels per acre to corn and 5 bushels to soybeans. At current crop prices, that means an extra 107 dollars per acre over a rotation. What...

Managing Phosphorus to Reduce Losses Phosphorus (P) is an essential plant nutrient. Sufficient phosphorus fertility means improved root growth and winter hardiness, accelerated maturity, and improved yields. However, when phosphorus makes its way off of fields through runoff or tile drains, it can negatively impact the health of rivers and lakes. Lake Erie is the strongest example of this locally....

With the delay in growing degree day accumulation and crop maturity, many fields are still in the ideal growth stages that put them at risk of some of our later season pests and diseases. Western bean cutworm (WBC) Peak moth flight for western bean cutworm has finally passed for all regions of the province. Central and eastern counties were the...

Keeping an eye out for Trochanter mealybugs in soybean

Monday, August 21, 2017

Author: Julia Mlynarek, Research Scientist – Field Entomology, AAFC-Harrow The Trochanter mealybugs Pseudococcus sorghiellus (Forbes) are small (at most 2mm), whitish, wax-covered insects that feed on plant roots (Fig. 1). Because of their size and life history, they are often overlooked but have been found in Southwestern Ontario. Trochanter mealybugs are part of a family of unarmored, scale insects that...
