Norman, D., and Alvarez, A. Rubbing alcohol can be used as a sanitizing agent. It’s essential that you prune the affected foliage away from the plant using sterilized pruning tools. They may take a long time to enlarge but eventually they can encompass the entire leaf margin, invade the center of the leaf and even cause leaf abscission. When the spathe is infected the disease is often called "flower blight" (Fig. K. M. Delate and E. R. Yoshimura, eds. dieffenbachiae. The capacity of X. axonopodis pv. 47. These lesions turn black and remain wet appearing as they enlarge. Solution: Fungal diseases are the most common problem in anthuriums. The pathogen causing bacterial blight disease of anthurium was isolated by standard techniques from leaf samples of diseased anthurium plants collected from different parts of Kerala, India.

Nishijima, W. T. 1994. Shehata, S. 1992. dieffenbachiae was captured from aerosols in relatively low numbers, primarily during rain and sprinkler irrigation events. Use of monoclonal and pathogenicity tests to characterize strains of Xanthomonas campestris pv.
