Other than the normal lingering Phytophthora root rot issues and occasional Alternaria escapes, few pest issues have been reported over the past few weeks. Except for some severe spring storms, weather conditions have been ideal for ginseng production up to this point with mostly dry weather and normal temperatures. Although temperatures have occasionally been hot, there have also been plenty of cooler days and nights to reduce plant stress. Temperatures are forecast to be above normal beginning this weekend, which could increase plant stress. Along with longer dew periods at this time of year, this could increase Alternaria disease pressures. Although most areas received a much-needed rain early last week, rainfall since then has been more sporadic. It is important to monitor soil moisture closely and ensure timely irrigation to reduce plant stress and the risk of Alternaria outbreaks.
