Weekly in-season progress reports of the Ontario field crop landscape
Plan to Assess Field for Ear Rot and Mycotoxin Risk With assistance from the Ontario Agri Business Association (OABA) and funding through the Grain Farmers of Ontario, Ontario Ministry of Food and Rural Affairs (OMAFRA) and Agriculture and Agri-Food Canada (AAFC) will begin sampling grower corn fields to determine ear mould incidence and occurrence of […]
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 […]
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 […]
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 […]
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 […]
Parts of southwestern Ontario remain dry, while eastern Ontario continues to have frequent rainfall and saturated soils in many areas. While yields have been good, making dry hay continues to be a struggle for many growers under the later conditions. Winter wheat harvest has continued this past week in eastern Ontario. Most fields in the […]
Western Bean Cutworm Update Western Bean Cutworm continues to be a concern for pollinating corn in areas with high trap counts. Peak moth flight has occurred in some of the counties in the southwest but counties east and north of Middlesex and those in Central and Eastern Ontario have not reached peak yet. Moths will […]
Cover Crops The underseeded red clover is looking pretty good where the winter wheat has been harvested. As is often the case some fields have variable stands and others have poor or non-existent stands. If the red clover stand is poor and it is insured nothing can be done until it is released by Agricorp. […]
General Another large hit of rainfall in eastern Ontario has put a stop to field work in the area again. Other parts of the province were slowed down by smaller amounts of rainfall over the weekend and overnight Thursday; however combining and hay harvest have started again. The two week forecast is showing some real […]
Cereals Winter wheat harvest has begun throughout southwest Ontario but intermittent rainfall has caused delays. Some farmers in Essex County have finished harvest and initial word is that the quality and yield of the crop has been good. Harvest progress is likely 7-10 days behind what was observed in 2016 but comparable to the 2015 […]
Nutrient Deficiencies in Soybeans Leaf yellowing and slow growth is evident in many fields. Stressful growing conditions will amplify nutrient deficiency symptoms, insect feeding, and disease symptoms. When plants are already stressed it’s even more important to manage deficiencies wherever possible. Fortunately, weather conditions over the next four to six weeks are more crucial to […]
Western Bean Cutworm Western bean cutworm (WBC) traps have been set on corn and dry edible bean fields across southern Ontario, and low numbers of moths are being caught. Traps are used to monitor moth activity (Figure 1.) and indicate when scouting is required, and are not intended to determine when to spray insecticide. Up […]
Diagnosing Early Season Soybean Diseases In Ontario, soybean seedling diseases and root rots are the second most important yield limiting diseases (Figure 1.) and this year is no different. Cool soil temperatures along with early rains in parts of Essex and Niagara resulted in a large number of soybean fields needing to be replanted and […]
Nitrogen Rate Decisions for Corn Split nitrogen applications in corn not only minimize risk of loss, but can also provide an opportunity to adjust rates based on rainfall, which is a key factor in corn response to nitrogen from year to year. Use decision support tools to help with your rate decision and don’t underestimate […]
Cereals A large majority of the winter wheat crop has progressed beyond the post-flowering stage, and spraying for Fusarium Head Blight protection has been completed in many regions. Stripe rust is reported to be advancing in some areas in fields that did not receive a fungicide application. Significant yield loss can occur in cases where […]
