A Brief Introduction to the New Citrus Rootstock Selection Guide Online!

More than 20 different factors can be involved in making a citrus rootstock selection. This includes horticultural, site, pest and disease factors. With 45 rootstock options, how do you narrow down your choices to the best candidates? One way to make more sense out of the possibilities is to use a guide. You want to arrive at a decision by focusing on your specific site, then take into consideration the performance of your trees on a particular rootstock at that site.

We’d like to introduce you to a new online version of the Florida Citrus Rootstock Selection Guide to help you do just that. This online guide is an interactive version of the University of Florida IFAS EDIS edition you might already know about. Here’s the link:

This site (Fig. 1) has new tools to help you quickly research established as well as recently released citrus rootstocks. Its features include 1) a sortable table of rootstocks and associated ratings, 2) quick links to rootstock literature and more. Table 1 provides a brief outline of the site’s other features. Check the site every so often to stay up to date with the latest information and features. And be sure to let us know what you think. We want to make this site our central location for new rootstock information and how we can make it better with your feedback!
