Non-corn options for livestock producers to manage Bt-resistant corn rootworm

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 […]

Managing Jointing and Non-Jointing Grasses

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 […]

Forage Options to Replace Silage Corn

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 […]

July 2020 Forage Report

Alfalfa plants exhibiting characteristic hopperburn: a yellow V shape on the tips of the leaves.

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 […]

Forage Options Following Wheat

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 […]
