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.
