Black root rot impacts a range of woody and herbaceous ornamental plant species primarily in greenhouse ornamental plant production, but also in home and commercial landscapes and nurseries. This disease causes decay of the root system and leads to yellowing, wilting, and necrosis of foliage. It is widely distributed and has been described on approximately 30 plant families in many parts of the world. Some of the most frequently impacted ornamentals are pansy, viola, Calibrachoa, annual vinca (periwinkle), Salvia, petunia, Persian cyclamen, snapdragon, Begonia, Verbena, Phlox, and Gerbera daisy. In addition to ornamental plants, some vegetable and other agricultural crops are also susceptible to infection.
Many ornamental crop species (including trees, shrubs, and bedding plants) are susceptible to diseases caused by Phytophthora, a genus of plant-pathogenic oomycetes (also known as water molds) that can persist in soil for several years. This publication rates common bedding plants, shrubs, and trees on their resistance to Phytophthora.

Botrytis blight, or gray mold, is a fungal disease that is widespread in the United States and globally. This fungus spreads via spores in the air and can result in economic losses if not managed early. In North Carolina, this pathogen is most threatening in the spring when temperatures are cool. This factsheet provides information about the disease, how it spreads, when it is a problem, and how to manage it through cultural and chemical practices.
