OMAFRA Field Crop Team August 12, 2019 283 Comments Off on OMAFRA Field Crop Report – Week of August 12, 2019Winter 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…
Western bean cutworm (WBC) Peak moth flight is likely taking place this week for many regions of Ontario, putting both corn and dry beans at risk (Figure 1). WBC moths prefer pre-tassel to full tassel corn to lay eggs in so scout these fields first. If corn has passed these stages in the immediate area, moths will choose to lay…
Nitrates in Silage Fast-growing crops can accumulate nitrates under dry weather conditions. This is most common in corn, but sorghums, sudangrass, millets, cereals, and Italian ryegrass can all accumulate high levels of nitrates and potentially cause nitrate poisoning in livestock. Figure 1. Fast-growing forage crops like sorghum-sudangrass may accumulate nitrates under stressful growing conditions Why are high nitrate levels a…
Nitrates in Silage Fast-growing crops can accumulate nitrates under dry weather conditions. This is most common in corn, but sorghums, sudangrass, millets, cereals, and Italian ryegrass can all accumulate high levels of nitrates and potentially cause nitrate poisoning in livestock. Why are high nitrate levels a problem? Nitrates (NO3-N) are converted to nitrites (NO2-N) in the rumen. Normally, the…
Winter Wheat Harvest Harvest has been slow to start in the province, lagging 7-14 days behind last year. Early yield and quality reports have been decent given the late planting date and challenging spring, but more acres will need to be harvested before any generalizations can be made. In fields were there are concerns of fusarium head blight (FHB), there…

Pesticide Drift Pesticide drift is a complicated subject and it carries significant financial and emotional baggage. This season has been challenging for many agricultural sectors and practices, and spray applicators have been challenged with difficult timing and limited opportunities for herbicide applications. When sprayer operators are rushed or frustrated they have to make hard decisions, and this sometimes ends badly….
Corn Early planted corn reached the ‘knee-high by the 1st of July’. Crop stages range from 12 leaf stage to still a few acres being planted. More so on the heavier soils some unseeded corn acres remain. Corn planted this late will have high harvest moisture and could be difficult to combine pending fall conditions. For the most part, plant…
Corn Grain corn planting is complete on intended corn acres except on heavy clays that received more rain this week. Crop stages range from 8 leaf stage to newly emerged. Overall plant stands look good on lighter and medium textured soils although plant stress is becoming evident on corn seeded into less than ideal conditions. There were reports of tough…
Corn Grain corn planting is largely wrapped up. Depending on the region, anywhere from less than 10% (heavy clays) to 90%+ of intended corn acres have been planted. There were a small number of growers in higher heat unit regions intending to plant final fields of grain corn before the forecasted rain on Thursday, June 20th. There is also still…
OMAFRA Field Crop Team June 13, 2019 2393 Comments Off on Ontario Field Crop Report – Week of June 10th, 2019Corn 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…
OMAFRA Field Crop Team June 6, 2019 1934 Comments Off on Ontario Field Crop Report – Week of June 3rd, 2019Corn 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…
OMAFRA Field Crop Team May 30, 2019 2052 Comments Off on Ontario Field Crop Report – Week of May 27th, 2019Planting 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…
OMAFRA Field Crop Team May 23, 2019 3337 Comments Off on Ontario Field Crop Report – Week of May 23rd, 2019Weather 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….
OMAFRA Field Crop Team May 16, 2019 1872 Comments Off on Ontario Field Crop Report – Week of May 13th, 2019The weather story continues this week with very little change across the province in terms of field activity, including fertilizer and pesticide application to wheat, manure application, field preparation and planting. A small number of acres were planted on the lighter soils across the province, where conditions permitted, but to date less than 10% of corn is in the ground….
