Forage soybeans are not normally recommended as an emergency forage. Forage soybean production has a steep learning curve. Successful producers started with a small acreage and took several years to learn how to manage this crop. Whole unroasted soybean seeds pose a risk of ammonia toxicity. Limit to 2-4 lbs/head/day. Protein exceeding animal demand will require feed energy for excretion….
Regrowth rates of hay fields following a cut and pastures following a grazing event is dependent on rainfall. Areas that received below-average rainfall may experience slower regrowth. Producers looking to buy or sell hay are encouraged to check out the new and improved Ontario Hay Listings website Southwest According to AAFC, most of the area south of Highway 7 received…
Many management decisions affect hay quality. After deciding when to cut, the next big decision is about the moisture content. Accurately timing how long to let the crop wilt when harvesting a forage crop will help ensure that it stores well. It either needs to have enough moisture to ferment correctly (silage/haylage or baleage systems), or low enough moisture…
Rain events across the province have interrupted a dry spring. While the water is welcome, the 5-7 days after a rain that ends a severe dry period increases the risk of nitrates in forage crops! Nitrates are of concern because they can increase silo gas production and cause nitrate poisoning in livestock. Silo Gas Silo gas (nitrogen dioxide, N2O) is produced…
Alfalfa weevil and potato leafhopper (PLH) are being reported as extremely high in many fields. Hot dry conditions have made it more favourable for these pests than their natural enemies (especially entomopathogenic fungi). Scout fields to determine if cutting is possible or if an insecticide application is necessary if thresholds are reached. Consider fields at threshold if both pests are…
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 816 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 805 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 1213 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 2077 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…
