Citrus ID

Citrus ID is an application designed to aid in the identification of various citrus pests and diseases. It serves as an indispensable tool for those working in or surveying citrus orchards, as well as enthusiasts cultivating citrus varieties in their home gardens. While the United States is home to many species within the Rutaceae family, the focus is primarily on crops most likely found in cultivation settings.

This tool serves as a comprehensive database, with over 500 types of citrus and related cultivars grown in the U.S.A. Often, originally released cultivars are listed through state programs and entities such as the National Clonal Germplasm Repository for Citrus & Dates. By synthesizing information from various state-specific programs, it facilitates precision in identifying these plants.

Identifying the exact cultivar may be challenging due to the complex breeding history of citrus and the selection emphasis on traits like taste and resistance over ornamental traits. However, this tool is capable of guiding users at least to the correct group level, such as distinguishing between sweet and sour oranges.

The visual aids provided are derived from the North Carolina State University Herbarium, and users should note that any use of these images beyond personal identification requires permission.

Citrus ID, an initiative backed by the USDA APHIS ITP, Fort Collins, and North Carolina State University, ensures access to the most accurate and relevant information when handling citrus cultivars. This helps both professionals and hobbyists significantly enhance their knowledge and management of citrus species.
