And Their Control ANR-1087, New Jan 1998. By Austin Hagan, Extension Plant Pathologist, Professor, Plant Pathology at Auburn University. And Their Control Introduction Members of the genus Ilex or holly are landscape favorites throughout the United States. Popularity of this group stems from their diversity of leaf texture, fruit and foliage color, size, and their adaptation to a broad range of climatic conditions. When compared with other woody landscape plants, holly have relatively few serious diseases.
Most diseases are more damaging in the nursery than in the landscape.
In the landscape, pests such as spider mites, scale insects, and spittle bugs usually pose more of a threat to the health and beauty of holly than do diseases or plant parasitic nematodes.
