Winter of 2020-2021 was mild. Although snow cover was less than normal, there were relatively few thaws. A rapid thaw in early March melted most of the snow. The warm temperatures persisted for a few days, allowing perennial forages to break dormancy. Dry conditions throughout March with warm days and cool nights provided a window to frost seed that lasted…
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. When can I frost seed…
Cereals can be used instead of corn as an energy source in livestock rations, and this substitution can help disrupt corn rootworm life cycles in the field. When growing cereals for feed the key areas to focus on include variety selection, establishment, fertility and disease management. Winter Cereals Growing a great cereal crop starts with selecting a variety that is…
Silage corn is grown to provide energy and fibre in a ration. It has very high yield potential. In addition to breaking corn rootworm lifecycles, alternatives to silage corn need to offer similar yield and nutritional value (Table 1). Producers should consult a livestock nutritionist to ensure rations are properly balanced. Table 1. Typical nutritional quality and yield of some annual forage…
Christine O'Reilly January 11, 2021 714 Comments Off on What is the true cost of Alfalfa Snout Beetle on your farm?This article was written by Dr. Elson Shields, Department of Entomology, Cornell University, Ithaca, NY **A note from Christine: Alfalfa snout beetle is an invasive species. A 2008 survey confirmed its presence in Leeds & Grenville, Prescott & Russell, and Stormont, Dundas & Glengarry counties. At that time, over 150 km2 were infested. Dr. Shield’s research on biocontrol nematodes was…
Christine O'Reilly January 6, 2021 728 Comments Off on Taking Root: Management Options for Bt-Resistant Corn Rootworm on Ontario FarmsThis webinar features OMAFRA specialists who provided an update on Bt-resistant corn rootworm, the impact on cropping systems and feed supplies, mitigation strategies to reduce the impact of Bt corn rootworm resistance, and alternative feeding options. While this webinar is open to anyone, it is geared towards cattle producers (dairy and beef). The webinar aired December 8, 2020. Speakers include…
OMAFRA Field Crop Team October 9, 2020 1071 Comments Off on Non-corn options for livestock producers to manage Bt-resistant corn rootwormIn fields where Bt rootworm corn hybrids have been used for more than three consecutive years, resistance among corn rootworm populations is suspected. Growers can no longer rely solely on Bt hybrids for protection against rootworm injury. The best management practice to reduce the resistant rootworm population is to rotate out of corn for at least one year. Growers are…

Silage Corn In fields where rootworm Bt hybrids have been used for three or more consecutive years, resistance among corn rootworm populations is suspected. Producers can no longer rely solely on Bt rootworm hybrids for protection against rootworm injury. See the 2020 Canadian…
Christine Brown September 22, 2020 1954 Comments Off on Unraveling the Mystery of Soil: Manure’s ContributionChristine Brown, Sustainability Specialist – Field Crops, OMAFRA “A radical new way of thinking about soil has partially solved the mystery of why adding manure improves resilience, climate control, and crop yields.” – Dr. Andy Neal, Rothamsted Research. Have you ever wondered why forests can establish and thrive without being fertilized? Or, why grasslands, pastures, or roadside vegetation – including…
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 rapid rate. High prussic acid…
Christine O'Reilly September 21, 2020 643 Comments Off on Managing Jointing and Non-Jointing GrassesChristine O’Reilly, Forage and Grazing Specialist, OMAFRA Grass doesn’t just happen and not all species grow the same way. Understanding how different grass species grow enables producers to make good management decisions that maximize forage production in their hay fields and pastures. Jointing and non-jointing grasses respond differently to cutting, which directly affects productivity and persistence. In an established stand,…

Silage corn growers should check fields for rootworm resistance to Bt hybrids Scouting for corn rootworm injury in silage fields is important to detect potential resistance to rootworm Bt traits and…
Key Points: Rotating out of corn is the most effective way to reduce populations of Bt-resistant corn rootworm. To replace silage corn for 2021, establish fall rye or winter triticale immediately after 2020 silage corn harvest. After the cereal silage comes off in mid-May, establish sorghum-sudangrass and take two cuts. An energy source will need to be supplemented; producers should…
Photo above: Potato leafhopper damage (called “hopper burn”) is frequently mistaken for insufficient water. To maximize the forage yield of fall cereals next spring, research from New York state suggests planting fall rye or winter triticale 10-14 days before the optimal winter wheat planting date (Figure 1). September 1st is the deadline to report summer-seeded New Forage Seeding acres…
