With warmer temperatures wheat has really progressed across the province. Fields in southern Ontario are beginning to head out while fields further east and north are at or approaching flag leaf emergence. That being said, all herbicide applications should be wrapped up in those fields that are at or approaching flag leaf. Disease should be […]
The 2019 growing season has been a challenge for the winter wheat crop to say the least! While many winter wheat fields have been removed, a significant amount of stands remain and are being kept through to harvest. Given the wet conditions so far this spring and as we approach heading in many areas, it […]
As occurs most years, summer thunderstorms brought localized hail events through parts of Ontario, particularly during the last week of July (Figure 1). After a hail event, our first question is usually how much leaf tissue is still out there? When evaluating damage, it’s good to wait a week or so before going in. This […]
Winter Wheat: Although progress has been made on nitrogen applications, the rainfall has delayed this operation in some parts of the province. The wheat is roughly 1 week ahead of long term average development. Some winter wheat is at the 1st node stage putting it past the optimal weed control timing window (Figure 1). The […]
Conditions: Warm, sunny and dry conditions over the last 2 weeks were ideal for field work. Timely rains May 10-12 brought 20 mm (5 to 50 mm) of welcome precipitation across eastern Ontario. With most of the cereals, new forage seedings, corn and part of the soybean acreage seeded/planted between April 27th and May 10th, […]
A well-planned and run on-farm trial is a great way to test new ideas, products, and equipment. But, to provide meaningful information, even a simple on-farm trial takes time to plan and carry-out. For an on-farm trial to provide useful information, two basic requirements need to be met. First, the trial has to be set […]
Horst Bohner, Soybean Specialist, OMAFRA, Stratford Albert Tenuta, Field Crop Plant Pathologsit, OMAFRA, Ridgetown Prolonged dry conditions can reduce soybean yield at any stage of development, but plants are more susceptible during germination and the reproductive growth stages. Dry soil conditions during germination will reduce plant stands. Severe moisture stress is evident by leaf wilting […]
The hot, dry weather conditions to date have not been very conducive to foliar leaf diseases across most of the province. In most cases, besides high relative humidity, prolonged wet conditions on the leaves are necessary for infection but only under favourable temperatures (16-30oC). What has started to show recently in the southwest are the […]
There are many different diseases which are caused by various fungal pathogens that affect cereals in Ontario. The foliar diseases (powdery mildew, leaf rust, Septoria leaf spot, Septoria (Stagonospora) glume blotch and tan spot) and Fuarium Head Blight (FHB) can cause significant yield losses if not managed correctly. Although these diseases occur in all […]
