Co-authored with Albert Tenuta, Pathologist, Field Crops In 2016 the milder winter conditions resulted in early leaf and stripe rust infections in Tennessee and Kentucky. This resulted in rust spores being blown into Ontario earlier than we typically see. By mid-May 2016, stripe rust was prevalent in most areas of southwestern Ontario. Growers who selected tolerant varieties or applied a…
Before long, the 2018 winter wheat crop will be seeded across the province (Figure 1). Long-term research at the University of Guelph’s Ridgetown campus shows that winter wheat in rotation provides an additional 10 bushels per acre to corn and 5 bushels to soybeans. At current crop prices, that means an extra 107 dollars per acre over a rotation. What…
True armyworm have been found in a few fields this weekend. Cereals, corn (especially, though not exclusive those fields planted into rye) and mixed forages are at risk and should be scouted every three or four days over the next three weeks. True armyworm identification was covered in a previous blog this spring (here). Scouting Guidelines: The best time to…
When we think about getting the highest yields and the best quality out of our winter wheat crop we tend to think about management practices such as timely planting, variety selection, nutrient management (nitrogen, phosphorus, potassium and sulphur), as well as timely fungicide and herbicide applications. However, one management practice that can often be overlooked or forgotten about in terms…
Two more pests deserve our attention over the next month. Cereal leaf beetle (CLB) is starting to show up in some fields in Ontario. Levels are still low but both adults, eggs and/or larvae are being found by scouts at various locations during routine scouting trips. A few locations tend to experience a higher frequency of infestations including fields near…
Crop yields have increased significantly since fertility recommendations were developed in Ontario. Crop nutrient uptake and grain nutrient removal have increased proportionately. A study was initiated in 2011 with funding from the Grain Farmers of Ontario to evaluate a corn-soybean-wheat rotation on four sites with relatively low soil test P and K levels. Areas within each test site were built…
The updated Organic Field Crop Handbook is now available for purchase on the Canadian Organic Growers’ website.
Co-written by Joanna Follings, Cereal Specialist Should you use 2,4-D to emerged wheat in the fall to control weeds? The short answer is no. First, the label clearly states under the “Application Timing” section: “Do not apply to seedling winter cereals in the fall.” Second, there are other labelled and less injurious herbicide options that provide equivalent or better control of…
Despite the dry year and stripe rust infestation, we saw some big winter wheat yields across the province this season. Many growers are giving credit to a strong stand establishment last fall thanks to the excellent planting conditions. So as we get into the full swing of winter wheat planting, here are a few things to keep in mind that…
Earlier this year, Grain Farmers of Ontario (GFO) and the Ontario Agri Business Association (OABA) were involved in broad industry discussions regarding the implications of using ManipulatorTM, a plant growth regulator, in the 2016 wheat crop. ManipulatorTM is not registered for use in the United States so the U.S. Environmental Protection Agency has zero tolerance for any residues of the…
Cashcropper allows you to compare the net profitability and fertility requirements for different crop rotations within a given field. This app is powered by over 30 years of data on crop yield responses to different rotations from trials conducted by the University of Guelph. The app uses default yield values provided by crop insurance records in Ontario and uses the…
Over-night temperatures on May 22 to 23 dipped to -2 to -3 oC in many parts of Ontario. Cereal crops are hardy to light frosts. Leaf tissue on plants that have not hardened off will withstand temperatures of -4 oC or lower before the cells will freeze and damage occurs, making late spring frosts of little consequence.
28% has become the preferred nitrogen source on winter wheat in Ontario. Application is perfectly uniform, something that seems difficult to achieve with most urea applications. However, leaf burn is one of the main problems with 28% applications, particularly at later stages of growth. With more emphasis on split nitrogen applications, and renewed interest in even later N applications on…
Wheat yields pushing 150 bu/ac are very possible with good management and increased nitrogen (N) rates. Recent research clearly shows an interaction between fungicides and nitrogen. But high nitrogen rates immediately raises questions about lodging, nitrogen source, and application timing. Wheat’s nitrogen demand is much earlier than corn, so nitrogen management needs to be different. What is the right rate,…
Synopsis: Using the provincial performance trials to pick the top variety for your farm. By now you should have looked at the wheat variety trials (www.gocereals.ca). What an AMAZING amount of information. With new information, and combined charts, which table should you actually use? Managed or normal? For the first time ever (2013), there are variety comparisons using fungicides, or “managed”(Tables 1A,…
