2026–2027 Florida Citrus Production Guide: Rust Mites, Spider Mites, and Other Phytophagous Mites

Starting in 2026, the Florida Citrus Production Guide is available as two separate booklets. The first booklet will provide information that does not change frequently such as personal protective equipment (PPE) guidelines and the biology of many of the insects, diseases, and horticultural practices that are part of citrus production. The first booklet will be updated every 3 years.

This second booklet will be printed annually and include any pertinent updates to legislation that impacts Florida citrus production and all pesticide and PGR tables that were previously incorporated into each chapter. The chapters here on Ask IFAS will be amended should changes occur between printing. This allows for rapid updates to incorporate new knowledge.

The UF/IFAS Citrus Research and Education Center (CREC) is the oldest and largest off-campus experiment station in UF's Institute of Food and Agricultural Sciences (UF/IFAS) and is unique among research centers in that it focuses entirely on one commodity, citrus. [website]

The Department of Entomology and Nematology maintains tripartite priorities consistent with the mandate given to full-service landgrant universities and associated experiment stations: Research, Extension, and Academics. These programs are facilitated with state funding, extramural contract and grant funding, donations and gifts, and the collaborative efforts of cooperating agencies and institutions. The Department has coordinated faculty efforts and strengths into what could be considered major thrust areas for the Department. These areas of emphasis include: Behavior, Ecology, and Systematics; Biological Control; Medical, Veterinary and Urban Entomology; Nematology; Pest Management; and Physiology, Biochemistry, and Genetics.
