New educational presentations available to citrus growers


LAKE ALFRED, Fla.— Looking for news that you can use now to improve citrus grove management? Six new presentations from UF/IFAS researchers are now available for viewing on the UF/IFAS Extension citrus agents’ website. The presentations provide practical tips and information on urgent issues like improving grove management, managing root pests, keeping weeds in check and the benefits of individual protective covers.

Originally presented at the Citrus Growers’ Institute sponsored by the UF/IFAS Citrus Extension agents earlier in April, the 30-minute presentations were recorded and may now be viewed as a video presentation or as PowerPoint presentation in PDF format. Below is a brief description of each session.

Evaluating Nominal Thresholds as Decision Making Guides for Psyllid SpraysDr. Lukasz Stelinski, UF/ IFAS CREC

Overview: We investigated the potential of a usable threshold to increase sustainability of Asian citrus psyllid (ACP) management in citrus under conditions of high Huanglongbing (HLB) incidence.

Managing Root Pests and Pathogens in Young Trees with HLBDr. Larry Duncan, UF/IFAS CREC

Overview: Ongoing research seeks to understand whether managing nematode and root weevil populations in HLB damaged trees is profitable.

Applied Biological Control Research for Managing Asian Citrus PsyllidDr. Jawwad Qureshi, UF/IFAS SWFREC

Overview: Discussion on some of the work that we have been doing on lacewings, ladybeetles and parasitoid Tamarixia radiata.

Incorporating Lebbeck Mealybug Management with Current Management ProgramsDr. Lauren Diepenbrock, UF/IFAS CREC

Overview: Presentation of the most recent information that we have been gathering on the biology and management of the recently established and rapidly spreading pest, the Lebbeck mealybug.

Individual Protective Covers (IPC’s) Influence on tree performance, fruit production, pests, and diseases Dr. Fernando Alferez, UF/ IFAS SWFREC

Overview: Presentation on how IPCs prevent HLB and how changed growth patterns in young citrus trees affect fruit set and quality. Also show how other pests and diseases of concern are affected by the IPCs and the trees’ response to the new condition once the IPC’s are removed.

Keeping Weeds in Check – Updates for Tree-Rows and Row-Middles Dr. Ramdas Kanissery, UF/ IFAS SWFREC

Overview: The use of glufosinate-ammonium for post-emergence weed control and how to achieve the best results with this active ingredient, along with weed management in row middles using herbicides for chemical mowing and cover crops.
