Abstract

Begonias are susceptible to a wide variety of fungi, bacteria, and viruses, as well as nematodes and abiotic diseases. The systemic nature of some of the pathogens makes it likely that the diseases they cause can be found wherever vegetatively propagated begonias are shipped. Management of these pathogens is paramount for specialty propagators while growers purchasing plants must inspect incoming plants for symptoms and understand the biology of the pathogens involved in order to manage them effectively.
