Abstract
New diseases known locally as ‘hoja de perejil’ of tomato (Lycopersicon esculentum Mill) and ‘brotes grandes’ of potato (Solanum tuberosum L.) were first recognized in surveys of production fields in Bolivia during 2000–2003. Alfalfa (Medicago sativa) witches' broom and little leaf diseases of native weeds Morrenia variegata and mora-mora (Serjania perulacea) were also identified near to production fields. Phytoplasma aetiology was attributed to each of these diseases following detection and ini

Abstract
During 2003, surveys of sugarcane yellow leaf disease and papaya bunchy top-like disease were carried out on plantations in Havana province, Cuba, to determine the roles of weeds and Auchenorrhyncha insects in the epidemiology of these diseases. More than 250 plant and insect samples were collected and indexed by using a nested PCR for phytoplasma 16S rDNA with the generic primer pairs P1/P7 and R16F2n/R16R2. The PCR products were further characterized by restriction fragment length polymorphism
