Sneak Peek: November 2021 Citrus Industry

Tacy CalliesSneak Peek


The low initial U.S. citrus crop forecast for the 2021–22 season points to the need to plant more trees to sustain the country’s citrus industry. The November issue of Citrus Industry magazine features articles that will help growers take care of their young trees.

Two articles help answer the question of what to plant. First, University of Florida’s (UF) Ute Albrecht and her co-authors address the issue of scion-rootstock compatibility. They explain the different types of incompatibility and provide examples of what combinations to avoid. Next, Ariel Singerman, Stephen Futch and Brandon Page look at the economic performance of several different rootstocks on Valencias in three commercial groves. Find out what rootstocks generated the most revenue in Lake Placid, Babson Park and Felda.

Weed control is crucial for new citrus plantings, but sometimes young trees can be damaged by herbicides. An article led by UF weed scientist Ramdas Kanissery warns how injuries can occur in young trees and tells what damage symptoms growers should keep an eye out for. The article also provides tips for safe use of herbicides.

Asian citrus psyllid (ACP) management continues to be at the forefront in the ongoing fight against citrus greening. Managing this pest is paramount in young trees. UF authors Jawwad Qureshi, Lauren Diepenbrock and Davie Kadyampakeni share their research on ACP management with UV-reflective mulch and flush-timed sprays. Experiments at three Florida locations are evaluating the effects of these practices on ACP population levels and tree growth. Get the latest research results.

Also, not to be missed in the November issue is the last CEU Central article of the year. UF Extension agent Danielle Sprague’s article on personal protective equipment gives growers the opportunity to earn one continuing education unit (CEU) in the Core category for the restricted-use pesticide license in Florida. Read the article and pass the accompanying test to earn your free CEU.

Find all these articles and more in the November issue of Citrus Industry magazine, coming soon.
