All In For Citrus, Episode 82 June 2025

In the June All In For Citrus podcast, Michael Rogers gives an update on some of the activities keeping University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers busy this summer. Rogers is the director of the UF/IFAS Citrus Research and Education Center in Lake Alfred.

One of their big projects is helping to coordinate the citrus seminars for the upcoming Citrus & Specialty Crop Expo on Aug. 20–21 at the Florida State Fairgrounds in Tampa.

Rogers provides a sneak peek of the citrus presentations, which number more than 20. While the Expo program will focus on HLB management, additional topics will be addressed. This includes other diseases and pests, crop insurance considerations and more.

The citrus seminars will provide growers with the latest knowledge on how to optimize trunk injection of oxytetracycline (OTC). New research on OTC applications and degradation and how different varieties respond to treatments will be shared. There will also be a presentation on advancements in automated trunk injection.

Lukasz Stelinski, UF/IFAS professor of entomology and nematology, joins the podcast to give growers useful reminders on Asian citrus psyllid (ACP) management. He stresses the importance of new flush in timing insecticide applications targeting the ACP. Stelinski also emphasizes the importance of dormant sprays during the winter to really push the pest’s population down.

On the disease front, Megan Dewdney, UF/IFAS associate professor of plant pathology, speaks in the podcast about some key disease concerns this time of year, including phytophthora brown rot, algal spot and canker. She adds that melanose could be more problematic than normal due to recent weather patterns of heavier rainfall.
