Weekly in-season progress reports of the Ontario field crop landscape
Dimethoate Resistant Two-Spotted Spider Mite Populations in Ontario Soybeans Results from bioassays conducted on two-spotted spider mite (TSSM) populations collected in soybean fields across Ontario show the prevalence of dimethoate (Cygon or Lagon) resistance is high in some areas. Through a collaborative project with Dr. Vojislava Grbic, Professor at Western University, Dr. Ian Scott at […]
Corn Tar Spot Watch Begins! Tar spot has now been established in the midwestern US for almost a decade and is an annual concern in many Midwestern states like Illinois, Indiana, Iowa, Michigan, and Wisconsin. While tar spot was not as yield-limiting in these areas in 2022, it continued to expand its range across the […]
General Across much of Ontario major crops and forages are progressing well. Evidence of moisture stress is present on various crops, but some relief came over the period of June 11-14th with scattered rainfall periods. Keeping appraised of incoming rainfall is at the back of everyone’s mind. Be aware of various networks and stations where […]
General Field crops in general across Ontario are doing well and welcomed the rain of the past few days. The need for moisture is coming up as the corn begins rapid growth. Winter wheat looks good across the province although have been impacted by dry conditions in areas. Rain across the province was welcomed but […]
Conditions Planting has wrapped up across most of the province with the exception of acres going in after first cut forages or on some heavy clays that received rainfall before they were planted and edible beans. Some areas received back-to-back frost warnings, but damage has been minimal to date. Persistent dry conditions are presenting some […]
Conditions Outside of rains received last Friday and Saturday, conditions have generally been excellent for field work over the past week which has allowed planting to continue or wrap-up at a quick pace for most parts of the province. Cool night temperatures, including frost warnings in some areas, is expected to have minimal impacts for […]
Conditions Field conditions across the province have improved vastly over the last ten days. With sunshine and temperatures in the high teens to even high twenties in some areas, planting is rolling across a majority of the province. Field work began early last week with lighter soil but by late last week, work on heavier, […]
Conditions Weather conditions improved considerably beginning on Monday, with sunshine throughout the week and daily high temperatures ranging from the high-teens to mid-twenties (Celsius) in both southern and northern Ontario. Planting has begun on lighter soils and is likely to progress onto other soil types by later in the week. Other field activities, including second […]
Conditions Overall, April rainfall has been slightly higher than average. This week, cold and wet weather slowed crop and planting progress. Eastern Ontario received above average rainfall, while most of the rest of the province had average rainfall. Winter Wheat Weather conditions have caused winter wheat growth to stall. The crop continues to look very […]
Winter Wheat Winter wheat stands continue to look excellent with very high stem counts (up to 144 stems/sq ft) in the southwest. Most fields have received at least one application of nitrogen, with many opting to add sulphur. Fields that have not yet received a nitrogen or sulphur application are showing signs of yellowing. Manganese […]
Weather The weather late last week was unseasonably warm, with maximum temperatures exceeding 24˚C in most of the agricultural regions of the province. Crops already in the ground responded well to the heat and growth progressed quickly. With more typical single-digit temperatures this week, crop development is expected to slow, and staging should become more […]
Spring conditions have arrived across Ontario this week and some tillage and field preparation has started in fields with light-textured soils. Manure application is also underway. Taking a manure sample at the time of application is recommended and will help fine-tune fertilizer needs. Several heavy rainfall events in early April have some producers concerned about […]
Planting In March 2022, Statistics Canada estimated Ontario farmers intended to plant 2.3 million acres of grain corn, 6% higher than the 5-year (2017-2021) average seeded acres of 2.16 million acres (OMAFRA Crop Statistics). Spring arrived slow. Lingering snows and rain limited field work on all but the lightest soils in late April. A very […]
Over three million acres of soybeans were seeded in 2022. High prices have increased the farm gate value of soybeans to over 2.5 billion dollars. The Agricorp floating claim price was $18.72/bu in 2022. Rainfall was sporadic during key plant growth stages, so yields were variable across the province. Field averages ranged below 25 bu/ac […]
2021 Winter Wheat Planting Conditions Planting conditions varied across the province. Areas with ideal conditions and a timely harvest of edible beans, canola, and oats were able to seed winter wheat within the optimum date range. Other areas experienced above average rainfall in October that resulted in pooling and heavy tile-run wheat. Most planting was […]
