Abstract
‘Candidatus Phytoplasma brasiliense’ (CPB) is a phytoplasma originally discovered in South America and is known to infect a wide variety of economically important crops. It is most prevalent in Hibiscus spp., where it causes witches broom symptoms, and papaya, where it causes bunchy top. Recently, CPB was documented for the first time in North America in a new host, globe sedge. In this study, two quantitative PCR assays are developed: one using high-resolution melt curve analysis (HRMA) based

Abstract
A survey of weeds was undertaken in a palm nursery affected by lethal bronzing (LB) to identify a reservoir host of the causal phytoplasma. Three common species were identified; Urochloa maxima (Guineagrass), Sporobolus indicus (smut grass), and Cyperus esculentus (yellow nutsedge) and sampled over a period of 2 years. Each species was sampled 36 times and all three species were negative for the LB phytoplasma. However, three specimens of C. esculentus tested positive for the phytoplasma specie
