• Abstract

  Huanglongbing (HLB) incidence is increasing and threatening citrus production in São Paulo State, Brazil, despite multiple efforts to control the disease and its vector, the Asian citrus psyllid (ACP) (Diaphorina citri). The objective of this research was to study the temporal dynamics of HLB epidemics, under intensive disease management, in 177 individual commercial citrus blocks on a si…

• Abstract

  In the last decades, new scientific and technical tools were applied to the identification of microorganisms. Biochemical and pathogenicity protocols, before essential to the diagnosis of plant diseases induced by bacteria, were partially replaced by molecular methods. However, until now, these changes were not extensively applied in plant pathology laboratories in Brazil. As a consequenc…

• Abstract

  Huanglongbing (HLB, Greening) is one of the most important citrus disease worldwide. Its first detection in Brazilian conditions occurred in 2004 and, so far, more than 50% of the citrus orchards in São Paulo state are affected by HLB. There are no curative methods for this disease, and only new infections prevention can be adopted to minimize the related damages. New infections can be av…

• Abstract

  The citrus industry is an important agro-industrial activity in Brazil and much of the production is concentrated in São Paulo, which accounts for 73% of citrus production in the country. A major challenge for São Paulo citrus industry is the current epidemic of Huanglongbing (HLB), a disease considered the main threat to world citrus production. The HLB is associated with the bacterium '…

• Abstract

  Huanglongbing (HLB, Greening) is one of the most important citrus diseases worldwide. No curative methods are available for HLB and only preventive control strategies can reduce its damages and losses (HLB management). Those strategies has to be applied simultaneously and are: i) planting of pathogen-free nursery plants; ii) frequent elimination of symptomatic trees (roguing); and iii) ve…

• Abstract

  Para avaliar os efeitos de doses e modos de aplicação de nitrogênio na cultura do milho safrinha, serão montados dois ensaios, nos anos 1998 e 1999, na FCAVJ. O delineamento experimental será de blocos casualizados num esquema fatorial com cinco modos de aplicação do nitrogênio (todo na semeadura, todo em cobertura, 1/3 na semeadura + 2/3 em cobertura, 2/3 na semeadura + 1/3 em cobertura …

• Abstract

  Huanglongbing (HLB) is the most devastating disease of citrus and has spread to the main growing areas worldwide, including Brazil, USA and China. There is still no viable curative strategy or resistant citrus variety to control HLB and management is based in the reduction of inoculum, i.e. eradication of symptomatic trees, utilization of healthy seedlings and chemical control of vector p…
