  1. Sorghum-sudangrass and Teff
    Author(s): Mark Sulc , Author(s): Bill Weiss

    Many producers in Ohio have planted summer annual grasses this year to increase their low forage inventories. These include sudangrass, sorghum-sudangrass, forage sorghum, pearl millet, and teff grass. When should these grasses be harvested or grazed?

    The general guidelines for harvesting or grazing these summer annual grasses as listed in the Ohio Agronomy Guide are shown in the table below.

    Table 7-12: Harvest Information for Summer-Annual Grasses.

    We are quickly approaching the second good opportunity of the year for establishing perennial forage stands, which is in the month of August. Most of us were not able to establish forages this spring, and many existing stands were damaged by the winter followed by the heavy rainfall this year. It is time to make preparations and be ready to plant perennial forage stands in the next few weeks.

    Usually, we think of water and moisture as a way to put a fire out, but the opposite is true with hay and straw, which when too wet can heat and spontaneously combust. Most years this is more common with hay than straw because there is more plant cell respiration in the hay. This year the wheat is at various growth stages and straw seem to have more green stems than normal. When baled at moistures over 20% mesophilic bacteria release heat-causing temperatures to rise between 130⁰F and 140⁰F.

  4. Potato Leaf Hopper
    Author(s): Kelley Tilmon , Author(s): Andy Michel , Author(s): Mark Sulc

    Some alfalfa fields have been harvested for the first time and now is the time to scout the regrowth in those fields for potato leafhoppers (PLH).  At our Western Agricultural Research Center near South Charleston, OH the PLH numbers last week in early alfalfa regrowth were generally about half the number needed to reach economic treatment thresholds. However, PLH populations can change quickly, and second crop regrowth should be scouted at least on a weekly basis.
