About four years ago, Fernando Alferez started to test if citrus trees grown inside a protective mesh cover could be kept safe from the potential deadly Asian citrus psyllid.
New research from Alferez shows that citrus trees grown under individual protective covers (IPCs) show no signs of the greening disease. Specifically, scientists found that psyllids cannot penetrate the bags (IPCs) under which the trees are growing because the diameter of their openings is smaller than the insects.
The University of Florida will resume providing growers regular flower bud advisories as the critical time for citrus grove management begins this winter. UF Institute of Food and Agricultural Sciences associate professor Tripti Vashisth restarted the advisories December 2 and will continue providing them every other week through the spring.
UF/IFAS Extension Polk County Stuart Conference Center 1710 US Hwy 17 S Bartow, Florida
Host: Chris Oswalt, UF/IFAS Citrus Extension Agent
Presenters: Tripti Vashisth and Amit Levy, UF/IFAS CREC
Join UF/IFAS Citrus Research and Education Center scientists and tour a citrus nutrition trial and a gibberelic acid (GA) field trial.
Dr. Vashisth's field presentation will be discussing the results of a citrus nutrition field trial that was designed to provide an effective mitigation of HLB-infected citrus trees. The results of the trial indicate that HLB can be managed to some degree in the field using mineral nutrition. The results will include recommendations on how to use this information in existing groves.
Dr. Levy will be discussing and demonstrating methodologies using canopy density values to evaluate the efficacy of nutritional treatments used to manage HLB. This type of in-field technology can help growers determine quantitatively the results of HLB management programs. This evaluation methodology can be used for practices related to nutrition, pest, and disease management.
At the GA trial, Dr. Tripti Vashisth will make a field presentation of the use of timely gibberellin acids (GA) sprays to manage citrus flowering and citrus tree stress. The information provided will demonstrate the mitigating effects of GA on HLB-infected citrus trees. The information will provide growers with current recommendations and use rate information on this use of GA to enhance citrus tree yield.
Lunch will be provided. There is no cost but pre-registration is required.
Oranges, orange-like fruit, new grapefruit hybrids, tangerine types, and acid fruit.
Attendees will be channeled through the room in a singular direction, where they will be given an opportunity to sample fruit, peel fruit (when applicable), and score the general characteristics and traits of the displayed selections. Juice may be provided.
The Plant Improvement Team will be present for discussion and questions. Attendees are requested to refrain from socializing until they have completed the display. This typically takes around 45 minutes.
