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 […]
This 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 […]
In 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 […]
Photo: It is impossible to tell by looking at frost-damaged sorghum-sudangrass what the prussic acid levels may be. 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 […]
Christine 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, […]
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 […]
Christine 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 […]
AgriSuite is an interactive online collection of management tools and calculators, developed by OMAFRA that you can access from your desktop or mobile device. AgriSuite assists you with key crop fertilization management decisions and how they relate to optimizing crop production and protecting the environment. AgriSuite: The Field Management Calculator helps with nutrient balancing to […]
Photo: Many winter wheat fields were planted to an annual forage crop after harvest this year. Premiums for summer-seeded New Forage Seeding insurance are due to Agricorp September 15. 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 […]
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 […]
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 […]
With winterkill, winter injury and low first-cut yields in many parts of Ontario as well as higher land costs, there is interest in following winter wheat and other cereals with a forage crop to help supplement inventories. Not only can this approach produce some extra feed, it also provides cover crop benefits. There are a few double-crop forage options […]
Southwestern • According to AAFC, Lambton, Huron, Perth, Bruce, Grey, Dufferin, Wellington, Waterloo, and Halton counties had average amounts of precipitation for the month of June. The rest of the region had below-average amounts of rainfall. • First cut was fully underway the first week of June. • There have been many reports of true […]
Christine O’Reilly, Forage and Grazing Specialist , OMAFRA The soil health benefits of having a perennial forage in the crop rotation are better than any cover crop, because its living roots are in the soil for much longer. Hay prices have been strong over the last couple of years, and there is always a market […]
Cool conditions in the first half of the month slowed forage growth across the province. Victoria Day – the weekend before May 24th – was early this year, with the holiday falling on May 18th. This further affected perceptions of crop development, as many dairy farmers aim to start first cut based on the long […]
