Other Plant Disease — Worldwide/Unknown
Lethal wilt, a severe disease of oil palm, is spreading throughout South America. An incidence of about 30 percent was recorded in 4 commercial fields in Colombia.
Phytoplasmas were detected in symptomatic oil palms by using specific primers, based on 16S rDNA sequences, in nested polymerase chain reaction [PCR] assays. The phytoplasmas were then identified as _Candidatus_ Phytoplasma asteris, ribosomal subgroup 16SrI-B, through the use of restriction fragment length polymorphism (RFLP)
