Growing citrus under enclosures
Citrus production under protected environments reduces huanglongbing (HLB) disease incidence and damage by excluding the Asian citrus psyllid (ACP) vector from access to citrus trees by surrounding them with a screen barrier. In addition to protecting citrus from the disease, it greatly reduces insecticidal sprays applied to control psyllids. This reduces costs and selection for insecticide resistance in the psyllid.
