CUPS Protects Citrus from HLB and Storms

Daniel CooperCitrus Greening, CUPS, Research


A system designed to protect citrus trees from the deadly greening disease withstood the ravaging winds of Hurricane Irma last year, University of Florida scientists say. With reinforcements installed after the storm, they’ll likely withstand even more dangerous storms. Using citrus under protective screening (CUPS), growers can keep the Asian citrus psyllids away from their trees, said Arnold Schumann, a … Read More
