Preventing HLB (Citrus Greening) with Zinkicide

Zinkicide is an economically feasible and environmentally sustainable bactericide treatment for HLB-affected citrus trees to improve production, fruit quality, and grower profitability.

How It Works

This potent bactericide can be applied with existing pesticide application equipment. It uses specifically designed nanoparticles is to allow for systemic activity from spray or drench applications while avoiding phytotoxicity.

What is HLB?

Huanglongbing (HLB), also called citrus greening, is an invasive disease of citrus that is devastating the largest citrus industry in the US and threatening the other major citrus-producing regions. This disease causes significant crop loss for citrus growers because of increased premature fruit drop and reduced fruit quality (fruit is small and unpalatable).

  • The bacteria that causes the disease, Candidatus Liberibacter asiaticus, is transmitted by insects (the Asian citrus psyllid), and control of insect vector or bacterial plant pathogen has proven difficult.
  • Few bactericides are currently available, and due to the mode of insect transmission – bypassing the protective barrier bactericides provide on the outside of the plant – their efficacy is limited.
