To avoid this, dont give the plant any water until its potting compost is practically dry, and use only special, well-draining potting compost. The Anthurium is not that vulnerable to diseases but it can be subject to root rot or can become infested with aphids or scale insects. In the late 1930s and 1940s, growers in Hawaii learned how to propagate anthurium by seed, leading to increased cultivation and variation (26). Plant Cell Tissue Organ Cult. 53. Monitoring the spread of Xanthomonas campestris pv. Growth effects were most striking on A. andraeanum cultivars Rudolph, Marian Seefurth and several numbered cultivars. The bacterial diseases include bacterial blight and bacterial wilt whereas fungal diseases include Rhizoctonia root rot, phytophthora, and black nose disease. Youll usually find them clustered on the undersides of leaves or on the stems of the plant. On the other hand, if you like to go the DIY route, then mix a soil medium containing peat moss (50%), perlite (25%), and leaf mold (25%). The risks associated with latent infections in symptomless cuttings convinced growers to develop a pathogen-free tissue-culture program, which remains the most important component of a successful disease management program for anthurium blight today. Anazi the disease damages the leaves of Anthurium, they are deformed, becoming covered with growths. Be sure to disinfect your tools and hands afterwards, as the disease is highly contagious. Trop. In Hawaii, anthurium cultivars generally are hybrids of A. andraeanum and/or A. antioquiense, with varieties based on characteristics of the colorful spathe and upright spadix (Fig. Alvarez, A., Lipp, R., and Bushe, B.
