Protecting Trees: Beyond CUPS and IPCs

Ernie NeffHLB Management

Many Florida citrus growers have been using individual protective covers (IPCs) for several years primarily to protect trees from HLB-spreading Asian citrus psyllids (ACP). Smaller but increasing numbers of growers are utilizing the more expensive citrus under protective screen (CUPS) system to protect trees from ACP and HLB. Recently, Fernando Alferez informed growers in a virtual presentation about some other …
