SC Fruit and Vegetable Field Report- September 5, 2023

Midlands Region

Rob Last

  • After the storms in the Midlands, crops are looking good with minimal damage. The Lowcountry is still very wet.
  • Following the rain, diseases will be increasing both bacterial and fungal pathogens.
  • I am picking up some Southern blight in tomatoes along with downy mildew in cucurbits.
  • Please remember to check transplants for disease issues, particularly black rot in brassicas. It is easier to reject diseased plants before transplanting than to manage an existing issue. In the case of many bacterial diseases, management options are very limited.
Diseases are starting to pick up, like this Southern Blight.

Pee Dee Region

Brittney King

  • The tropical storm last week brought 4-6 inches of rain throughout my counties, so there was some flooding in low-lying areas of fields. Pumpkin vines suffered some damage from the wind gusts but have seemed to bounce back. A lot of debris was thrown into fields by the wind.
  • Scouting should be done regularly, especially after an event like a hurricane that can weaken a crop and increase its vulnerability to insects and disease.

Upstate Region

Andy Rollins

  • In cucurbits, we are finding downy mildew and phytophthora. In pumpkin, we are seeing major issues with stem rot from phytophthora on one farm.  It has been traced to irrigation ponds where water is being distributed across multiple fields. The extended cool, wet spring is thought to have contributed.
  • Strawberry growers are fumigating now. Make sure to fill out your fumigant management plan before beginning. Take your time and check the system for leaks beforehand. Make sure you remove your filter and clean or replace it. Most of all, be careful, as these materials are too dangerous not to be treated with respect.
  • Harvest of muscadine has begun, although still slow.
Downy mildew is present on cucurbits in the Upstate.
