Huanglongbing (HLB) was first discovered in Florida in 2005. It can now be found in all counties in the state where commercial citrus production takes place. HLB is a bacterial disease that is transmitted by the Asiatic citrus psyllid. HLB negatively affects citrus producers in several ways, including reduced yield, increased grove maintenance costs, and increased tree mortality. The research presented in this article suggests that another consequence of HLB is its adverse effect on the willingness of producers to invest in new plantings. Reduced plantings imply reduced fruit production in the future.

This 4-page fact sheet examines the impact of the presence of citrus greening on new tree plantings in the Florida citrus industry. Sweet oranges are by far the most important citrus variety grown in Florida, so the analysis is limited to sweet orange plantings. Because citrus greening impacts citrus producers through reduced yield, increased mortality, and increased cost of production, it is expected that the presence of citrus greening has had an adverse impact on the willingness of growers to invest in new trees.
