Ray Royce, executive director of Highlands County Citrus Growers Association, was surprised that the initial Florida orange forecast for the 2021-22 season was only 47 million boxes. “I had hoped we’d be a lot closer to what our final numbers were from last year,” he said. Actual production in 2020-21 was 52.8 million boxes. The crop forecast was issued by …
Two short videos about HLB-related research were available at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) booth at Citrus Expo in August. The videos are available online for viewing. UF/IFAS researcher Tripti Vashisth narrated the video, HLB-Associated Preharvest Fruit Drop. She said up to 40% of fruit can drop from mildly HLB-symptomatic trees shortly before harvest, …
By Tripti Vashisth and Christopher Vincent This article summarizes current knowledge about HLB-associated preharvest fruit drop. Unfortunately, exactly how HLB induces preharvest fruit drop is still unknown. Nonetheless, this article links what we do know about HLB-associated fruit drop to fruit drop in HLB-free trees and how strategies, such as managing tree water status and use of gibberellic acid, can …
Florida citrus grower Kyle Story of The Story Companies thought the initial Florida orange crop forecast for the 2021-22 season was “realistic.” But the 47-million-box forecast struck fellow grower Paul Meador as low.

Editor’s Note: Tripti Vashisth with share new information on the use of gibberellic acid treatments to improve health and yield of HLB-diseased trees in a virtual seminar on Sept. 21. Register here. Researcher Tripti Vashisth told the recent Citrus Expo audience how fruit drop might be reduced through the use of nutrition and irrigation strategies, gibberellic acid and increased fruit …
By Tripti Vashisth, Megan Dewdney and Lauren Diepenbrock Citrus flowers profusely, but less than 2% of the flowers become harvestable fruit. In other words, 98% of the flowers seen during bloom will end up on the grove floor at some point during fruit development, whether as a flower, fruitlet, young fruit or mature fruit. Profuse flowering allows trees to produce …
Frequent irrigation with good quality water can improve fruit growth and development and overall productivity. By Tripti Vashisth HLB-affected citrus trees have small and weak root systems. Though the roots are efficient in taking up water and nutrients, there are not sufficient roots to support the tree’s canopy requirement. Therefore, the trees often experience water and nutrient deficit. Not all …
Tripti Vashisth revealed new research information on what causes preharvest fruit drop and possible strategies to mitigate the problem. The Florida citrus industry, stricken by HLB, has suffered a sharp increase in preharvest fruit drop, leading to a substantial reduction in citrus production. According to Vashisth, assistant professor of horticulture at the University of Florida Institute of Food and Agricultural …

Citrus flowers profusely, but less than 2 percent of the …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus scientists Tripti Vashisth and Fernando Alferez are trying to reduce the amount of fruit drop from Hamlin and Valencia trees prior to harvest. If fruit drops, growers can’t harvest it, and that leads to losses for farmers and less fruit at the market for consumers. Normally, about 10 to …
By Tripti Vashisth, Garima Singh and Megan Dewdney Citrus trees grown in the field undergo various types and levels of stress continuously.
