Sclerotinia Diseases in the Vegetable Garden

Last week was our annual tour of commercial vegetable growers in West Feliciana Parish. AgCenter personnel and several of the commercial growers met and spent the morning touring the various growers’ operations. We saw some early blight on tomatoes, but the highlight of the day was the white mold on beans and timber rot on tomatoes, both caused by the fungus Sclerotinia sclerotiorum. The cool nights, wet weather and close spacing of the plants made the conditions ideal for the development of these diseases.

      Dale, Unfortunately, there’s probably not much you can do at this point except to identify the cause of the problem so you can plan for next season. There are several soil-borne pathogens that can cause tomatoes to wilt and our recommendations will depend on which one is affecting your plants. FOr help in identification, you can either call your county (parish) extension agent or send samples directly to the LSU AgCenter Plant Diagnostic Center at 302 Life sciences, Baton Rouge, LA 70803. There is a $20 lab fee for diagnosis. I hope this helps. Don
