    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.

    Cool weather has slowed everything down including insect growth and development, and we could see problems with alfalfa weevil later than typical this year.   Alfalfa fields should be scouted weekly for weevils until at least the first harvest.  Followup scouting may be needed after harvest in heavily infested fields. 

    Spot problem fields early by checking alfalfa tips for feeding damage – small holes and a tattered appearance.

    Forage stands will begin spring greenup in the next few weeks, especially in southern Ohio. While winter injury in forages is very hard to predict, this winter has presented some very tough conditions for forage stands. This is especially true of legumes like alfalfa and red clover. Producers and crop consultants should be prepared to walk forage stands early this spring to assess their condition in time to make decisions and adjustments for the 2019 growing season.

                Late season alfalfa management decisions often come down to balancing a need for forage versus stand health and winter survival.  Weather patterns across the state in 2018 have been variable.  Lack of summer rain in some areas have decreased forage yields, frequent rains or too much rainfall in other areas have blown apart harvest schedules and/or resulted in low quality forage inventories.  Taking a fall alfalfa harvest is an opportunity to increase both the quality and quantity of the farm forage inventory.  Like most farming decisions, there are trade-offs and risk factors to
