At harvest individual soybean plants that remain green may become evident. The whole plant or just the stem stays green and there are often fewer pods present on these plants. In severe cases the pods may also be small or rounded and have little or no seed. These pods are called parthenocarpic (seedless). There are a number of causes for…
OMAFRA Field Crop Team September 19, 2019 802 Comments Off on Ontario Field Crop Report – Week of September 16, 2019Fall Means – Sampling for Soybean Cyst Nematode! As fall approaches, two things are certain – winter will come and soybean cyst nematode (SCN) has done its business! For many growers, managing soybean cyst nematode means planting SCN resistance varieties BUT effective SCN management does not end when you have selected your soybean varieties! It is imperative to not only…
Tracey Baute September 5, 2019 766 Comments Off on Late Season Bean Leaf Beetle Activity in SoybeansBean leaf beetles (BLB) have reached the pod feeding threshold in some IP soybean fields this week. Despite the calendar date, both the beetles and soybeans are behind due to the delayed planting and slower accumulation of growing degree days. The first generation beetles coming out in July and August are attracted to later planted fields. But in more “normal”…
There is a long way to go yet before we reach crop maturity and a few insects are thriving right now in late planted soybeans and dry beans. Bean leaf beetles are a risk for both soybeans and dry beans. Reports are starting to come in of some activity at various locations. This is the first generation of adults; what…
Tracey Baute July 11, 2019 899 Comments Off on Pest Watch – Potato Leafhoppers, Thrips and Spider MitesWhat a year! Goes from too wet to too dry. With young crops and little canopy yet, a few pests could become a problem quickly. Especially if hot dry conditions continue to stress the crop further. Scout fields frequently for these three pests; Potato leafhoppers, thrips and spider mites. Potato leafhoppers (PLH) are in high numbers in many counties. Both…
It’s that kind of year. Expect the unexpected or at least don’t be surprised when something doesn’t follow the rules. It’s a wet year. That usually makes us more disease prone than insect prone. And entomopathogens (fungus that kills insects) usually kick in. But we are also dealing with very delayed planting with small plants emerging, and lack of timely…
OMAFRA Field Crop Team June 13, 2019 1354 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 1081 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 1152 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…
Horst Bohner May 23, 2019 1720 Comments Off on Is It Time to Switch to Earlier Maturing Soybean Varieties?The spring of 2019 has been unprecedented with excess rainfall and cool temperatures. This has significantly delayed soybean planting. When does it become necessary to switch to earlier maturing soybean varieties? There has been a trend in modern soybean production to plant early and to use long season varieties to achieve higher yields. This strategy has proven effective when soil…
OMAFRA Field Crop Team May 23, 2019 2224 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 1046 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….
OMAFRA Field Crop Team May 9, 2019 1025 Comments Off on Ontario Field Crop Report – Week of May 6th, 2019Weather The continuing thread of the story for this spring is the weather. Very little has changed across the province in the last week in terms of manure application, wheat fertilization, tillage and crop planting. We continue to wait on weather that allows fields to dry out and support equipment. Eastern Ontario did get a small window to get some…
Early planting has been adopted as a management strategy to achieve maximum yield in modern soybean production. There is considerable evidence that soybeans planted in late April and early May yield more than beans seeding during the second half of May. Ontario trials have shown that in some years early planting can provide a 10 bu/ac yield advantage. In the…
Jake Munroe December 17, 2018 2855 Comments Off on To plant green or to plant brown? Rye cover crop termination timing before soybeansCereal rye has several strengths as a cover crop option. It’s relatively inexpensive and easy to kill. Rye improves soil structure, builds organic matter and helps protect against water and wind erosion. It also competes with weeds, as Mike Cowbrough has written here (see Figure 1). However, in most cases, rye doesn’t put on much growth until the month of…
