Oxytetracycline hydrochloride (OTC-HCl) application for control of palm phytoplasmas

oxytetracycline hydrochloride

Phytoplasma diseases of palms are a major threat to the Florida nursery and landscaping industries. Historically, lethal yellowing has killed millions of coconut palms throughout the Caribbean and has been causing decline of over 30 species of palm in Florida since it was introduced to the state in the first half of the 20th century. In 2006, lethal bronzing disease was discovered on the west coast of Florida near Tampa. Currently, the only two management options available for control of phytoplasmas is an aggressive sampling strategy followed by consistent tree removal and injections of oxytetracycline hydrochloride, or OTC. This 2-page fact sheet written by Brian W. Bahder and Ericka E. Helmick and published by the UF/IFAS Entomology and Nematology Department seeks to provide a source of information and instruction on the injection of OTC into palm trunks.
