By Tripti Vashisth and Megan Dewdney This article discusses the use of gibberellic acid (GA), the naturally occurring plant hormone, on huanglongbing (HLB)-affected trees. The results were generated from a 3-year trial in which Valencia trees were treated with GA in the fall. The outcomes suggest that GA can be effectively used for synchronizing and suppressing profuse flowering without negatively …
A decrease in grapefruit production costs among Indian River growers allowed the average grower to approach the break-even point in the 2015-16 season, a University of Florida economist reports.

Grapefruit is an unpopular citrus fruit in the South African domestic market, the U.S. Department of Agriculture’s Foreign Agricultural Service (USDA FAS) reported recently. Consequently, only 5,000 metric tons (MT) of an expected 400,000 MT grapefruit crop in 2023–24 is forecast to be consumed in the country. The majority of South Africa’s grapefruit is expected to be exported. The production …
By Tripti Vashisth Huanglongbing (HLB) severity is associated with small fruit sizes and lower fruit numbers at harvest. Moreover, small fruit are more likely to drop and drop earlier during preharvest fruit drop. Unfortunately, management practices suggested to increase fruit size or reduce drop have had mixed results. So, before looking for ways to increase fruit size and number, it …

By Tripti Vashisth and Mary Sutton Citrus trees affected by huanglongbing (HLB) consistently have small fruit and low fruit numbers at harvest. The low fruit numbers are largely attributed to the increased rates of preharvest fruit drop that accompany HLB. Small fruit is more likely to drop during this preharvest period, suggesting a link between fruit size and retention. To …
European Union (EU) orange juice production in 2021–22 is forecast at 62,250 metric tons (MT) by the U.S. Department of Agriculture’s Foreign Agricultural Service (FAS).
