For over a decade, the Asian Citrus Psyllid has been present in the state of Florida, and among other states like California. While the insect itself causes minimal damage, the citrus greening disease or Huanglongbing (HLB) is causing irreparable damage because we currently do not have a chemical control of the bacterial disease. Due to limited methods of control, we are applying the pesticide Imidacloprid to citrus trees; the more susceptible Valencia orange in particular. It will be used on trees at the ages of one, four and eight years old with different irrigation schedules of 0.5, 1.0 and 1.5 ET. Samples will be collected up to a depth of 45cm. After the completion of the project, it is expected that the uptake efficiency will be improved by controlling the ACP, Imidacloprid will have a miniscule affect on water quality and residence time in root zone will be increased. This project is aimed to aid citrus growers in defending their crops against a bacterial disease.
