Corn Newsletter : 2018-13

  1. Septoria, wheat
    Author(s): Pierce Paul

    It is wet and rainy outside and the forecast calls for more rain throughout this the second week of May (May 14–19). Therefore, growers’ concerns about diseases and the need for fungicides are understandable. However, although most of our common diseases of small grain crops are favored by wet, humid conditions, it does not automatically mean that you have to apply a fungicide this week.

  2. alfalfa, forages

    Alfalfa stands in Ohio had a slow start this spring, but our recent change in weather is causing alfalfa development to move quickly. Stand growth is catching back up to where it would normally be at this time of year. As we approach the end of May many producers will be making harvest decisions.

    It is common for many growers to base harvest decisions primarily on alfalfa maturity; however, variable weather conditions affect the rate of bud and flower development in alfalfa and this method can be inaccurate.

  3. rainfall
    Author(s): Jim Noel

    Above normal temperatures will continue for the rest of May. Unlike temperatures, rainfall will be very inconsistent with a tendency to be wetter than normal. Some areas of Ohio will receive flooding rain while other areas will struggle to receive an inch or perhaps less than a half inch of rain for the rest of the month. Uncertainty is high for where the flooding rains will occur and where the driest areas are. Runoff will also be highly uncertain the rest of May.
