  2. Avoid Forage Toxicities After Frosts

    Author(s): Mark Sulc

    As cold weather approaches this week, livestock owners need to keep in mind the few forage species that can be extremely toxic soon after a frost. Several species contain compounds called cyanogenic glucosides that are converted quickly to prussic acid (i.e. hydrogen cyanide) in freeze-damaged plant tissues. A few legumes species have an increased risk of causing bloat when grazed after a frost. Each of these risks is discussed in this article along with precautions to avoid them.

  3. Seeding alfalfa

    Late Summer Establishment of Perennial Forages

    Author(s): Rory Lewandowski, CCA , Author(s): Mark Sulc

    Ohio growers experienced another wet spring and compressed 2018 spring planting season.  On some farms, this caused postponement of plans for spring seeding of alfalfa and other perennial forages.  In some areas, the prolonged wet weather affected forage harvest schedules, resulting in harvest equipment running on wet forage fields leaving ruts, compacted soils and damage to alfalfa crowns.  Some of these forage acres need to be re-seeded.

  4. Keep Scouting for Potato Leafhoppers in Alfalfa

    Author(s): Rory Lewandowski, CCA , Author(s): Mark Sulc , Author(s): Kelley Tilmon

    If you grow alfalfa, now is the time to scout those fields for potato leafhoppers.  Integrated pest management (IPM) scouts are finding potato leafhoppers (PLH) widely distributed across a number of alfalfa fields.  PLH numbers have ranged from low to well above economic treatment thresholds.

  5. Using PEAQ to Estimate Alfalfa NDF for Multiple Cuttings

    Author(s): Rory Lewandowski, CCA , Author(s): Mark Sulc

    Much of the region’s alfalfa crop has been harvested over the past two weeks.  As cooler temperatures move into the area regrowth will likely slow down. Once regrowth reaches 16 inches tall again, the NDF (neutral detergent fiber crude protein) can rapidly be estimated in the field using the predictive equations for alfalfa quality (PEAQ).
