Abstract

The Brazilian citriculture faces a new disease, huanglongbing (HLB), also known as greening, which is associated with Candidatus Liberibacter spp. The Coordenadoria de Defesa Agropecuária (CDA), Ministério da Agricultura Pecuária e Abastecimento (MAPA), and Agência Paulista de Tecnologia dos Agronegócios (APTA) have been executing actions for plant sanitary protection and disease control. About one year after finding the first symptomatic tree in Brazil, MAPA’s Normative Instruction number 10, of 18/03/2005 was published. It was later replaced by Normative Instruction number 32, of 29/09/2006. Both Normative Instructions prescribed the elimination of all symptomatic trees. Currently, the Normative Instruction number 53, of 16/10/2008, is in force, which guarantees higher agility in the fiscalization process, giving new duties to the grower and determining the elimination of not only symptomatic but also non- symptomatic plants in the same area, when symptomatic tree incidence is over 28%. Plant Protection Agency (CDA) has already released a new Instruction (CDA number 04, of 12/03/2009), delimiting and establishing the whole Sao Paulo State as an area under plant protection surveillance against the disease. The success of HLB control depends on a united action of all citrus growers. Therefore, the governmental actions aiming to eliminate the bacterial sources comprised by those properties whose owners do not follow the specific legislation, placing in risk the sanity of the plants in adjacent properties, are fully justified.
