Key Points When is the fall rest period? The fall rest period (sometimes called “critical fall harvest period”) for alfalfa is 450 growing degree days, base 5°C — or approximately 6-weeks — before the average date of the first killing frost (-4°C for several hours), when alfalfa stops growing. Not cutting during this period allows […]
Co-authored by Mike Cowbrough, OMAFRA Weed Management Specialist – Field Crops An annual ryegrass cover crop is excellent at scavenging nitrogen, improving soil structure, and preventing erosion. It tolerates low light levels well enough to be inter-seeded into an established corn crop and grows quickly enough with adequate moisture to help suppress weeds. For ruminant […]
True armyworm (TAW) has been spotted at near threshold levels in a winter wheat field near Niagara and has also caused significant damage in late planted seedling corn in Chatham Kent. Though most of our YEN wheat sites being scouted weekly have picked up only low levels of TAW in a few of the sites, […]
Key Points: What Causes Fires? The process of forage heating up and then burning is typically called spontaneous combustion. Spontaneous combustion for hay usually occurs within the first two months of storage. Unusual growing conditions, such as an early harvest window or immature crop, can complicate the drying process and increase the risk of fire. […]
Key Points: What Causes Fires? The process of forage heating up and then burning is typically called spontaneous combustion. In silos, forage can dry down if air enters the silo through leaks in walls or doors; this results in the potential for fires throughout the whole year. Spontaneous heating and combustion occur when sufficient moisture […]
This article was originally written by Joel Bagg in 2013. It was edited May 25th, 2022 by Christine O’Reilly to reflect current insecticide options to control alfalfa weevil. Alfalfa weevil can be an issue in Ontario, particularly in south-western parts of the province. While outbreaks tend to be isolated, they can be severe and dramatically […]
Frost seeding is a popular way to renovate an existing forage stand and is most effective in fields where patches of bare soil at least the size of a loonie are visible. With spring around the corner, many producers have questions about how to best use this technique to improve their hay fields and pastures. […]
Publication 30: Guide to Forage Production is a comprehensive guide to forage agronomy. It has information on establishment, fertility, weed management and weather stress for many species grown as forage in Ontario. It also covers harvest and storage of forage crops and understanding a laboratory forage analysis. To download a free PDF version or order a […]

Caution! Members of the sorghum family – sorghum, sudangrass, and hybrid sorghum-sudangrass – contain dhurrin, a glucoside that breaks down to release hydrocyanic acid, also known as prussic acid (hydrogen cyanide, HCN). A sudden disruption of growth such as frost, drought or cutting, causes prussic acid to be released inside the plant at a more […]

Bt-resistant Corn Rootworm Corn rootworm is a serious pest of continuous corn. Root feeding reduces yield and increases the risk of lodging and “goose-necking” which can […]

The optimal time to summer seed alfalfa mixes depends on the length of the growing season: More than 3100 CHU: August 10-20 2700 – 3100 CHU: August […]
The relationship between alfalfa breeding efforts and yield potential is complicated. While most literature on annual grain crops shows yield improvements with the release of new varieties over time, a literature search on alfalfa yield will show improvement, stagnation, and declines, depending on the paper. One of the latest attempts to discern what is really […]
South and West According to Agriculture and Agri-Food Canada: Bruce, Grey, Dufferin, Simcoe, Niagara, Elgin, and parts of Lambton and Middlesex received average or above average precipitation for June. The rest of the region had below-average rainfall. Above-average levels of winterkill reduced yields in affected fields. Although some dairy producers cut on their preferred calendar […]
Description Blister beetles are very rare in Ontario but have been occasionally found in alfalfa fields north of Lake Erie. They are more common in arid climates, such as the U.S. Midwest, and are often associated with grasshopper infestations. The three most common species are the black blister beetle (Epicauta pensylvanica), the ash grey blister […]
