Citrus Diseases Exotic to Florida: Citrus Tristeza Virus–Stem Pitting (CTV-SP)

Amit Levy, Ozgur Batuman, Peggy Sieburth, Ajia M. Paolillo, Kuang-Ren Chung, and Ronald H. Brlansky

This document is one in a series designed to provide important information on the causal agent, symptoms, and transmission of exotic citrus diseases. This information can be used as an educational tool to raise awareness about these diseases and for scouting and identification efforts. Disseminating information about the diseases to the citrus industry may prevent their introduction and spread in Florida. This document will focus on the exotic viral disease caused by isolates of citrus tristeza virus–stem pitting (CTV-SP). Major revision by Amit Levy, Ozgur Batuman, Peggy Sieburth, Ajia M. Paolillo, Kuang-Ren Chung, and Ronald H. Brlansky; published by the UF/IFAS Citrus Research and Education Center; 5 pp.

The Updated Seed Testing Rule for Lettuce mosaic virus in Florida

De-Fen Mou, Germán V. Sandoya, Anna Mészáros, Ozgur Batuman, and Trevor Smith

This publication aims to raise awareness of the updated Florida seed certification requirement for lettuce mosaic virus (LMV). Florida mandates that all lettuce seeds sold and used in the state must be tested and certified as LMV-free (i.e., zero infected seed per 30,000 tested for LMV). The information presented in this publication is directed to state and county Extension faculty, crop consultants, current and potential lettuce producers, seed companies, and home gardeners who grow lettuce in Florida.

Individual Protective Covers (IPCs) for Young Tree Protection from the HLB Vector, the Asian Citrus Psyllid

Fernando Alferez, Ute Albrecht, Susmita Gaire, Ozgur Batuman, Jawwad Qureshi, and Mongi Zekri

Psyllid exclusion is the most effective strategy to keep citrus trees free from HLB. Individual protective covers (IPCs) are a novel strategy based on psyllid exclusion of individual trees using a protective mesh bag. This new 3-page publication summarizes the knowledge we have accrued from our 3-year-long field studies using the IPC system and provides recommendations that can help with effective use of this technology. By F. Alferez, U. Albrecht, S. Gaire, O. Batuman, J. Qureshi, and M. Zekri.

Oxytetracycline Injections in Citrus: Cost Estimates for Early Adopters

Shourish Chakravarty, Tara Wade, Ute Albrecht, Ozgur Batuman, and Thomas H. Spreen

This publication provides per-tree and per-acre costs of adopting oxytetracycline (OTC) trunk injections for large-scale orange production in southwest Florida. The values represent the costs observed by early adopters (i.e., the 2023–24 season). This information will be helpful to citrus growers, Extension agents, and other citrus industry stakeholders interested in understanding the costs of trunk injection and OTC applications in tree crop production. The values shared are estimates; costs will vary depending on the operation’s application methods, products used, tree density, and other grove characteristics. Written by Shourish Chakravarty, Tara Wade, Ute Albrecht, Ozgur Batuman, and Thomas H. Spreen, and published by the UF/IFAS Department of Food and Resource Economics, June 2025.
