All In For Citrus, Episode 80 April 2025

April is a busy month for citrus events. The Florida Citrus Growers’ Institute was held in Avon Park early in the month followed by a citrus field day at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center (SFWREC) in Immokalee.

These events are the topic of the April episode of the All In For Citrus podcast. Michael Rogers, director of the UF/IFAS Citrus Research and Education Center, opens the podcast with a summary of the presentations given at the Florida Citrus Growers’ Institute. Covered subjects are psyllid management, rootstock interactions with oxytetracycline (OTC), the development of a Bacillus thuringiensis citrus tree, optimizing the use of plant growth regulators (PGRs) and an update from the UF/IFAS Crop Transformation Center.

Tripti Vashisth, UF/IFAS associate professor of citrus horticulture, discusses in more detail her Florida Citrus Growers’ Institute presentation on the use of PGRs like gibberellic acid to improve tree health and yields. Vashisth has developed a program approach utilizing various types of PGRs during different parts of the season.

 

Her results show yield and quality improvements in line with the use of OTC. She added that her PGR program would be a good option to apply during the label-required off year of OTC use. The PGRs are also a good complement to use with OTC.

Sarah Strauss, UF/IFAS associate professor of soil microbiology, details the SFWREC citrus field day and the tour stop she hosted on the use of cover crops and compost to boost soil and tree health. Her research is studying how compost in conjunction with cover crops can benefit soil.

 The podcast is a partnership between UF/IFAS and AgNet Media.
