Nutrition and Irrigation Management for Florida HLB-Affected Trees

Tripti Vashisth, Davie Kadyampakeni, and Jamie D. Burrow

This is a two-sided poster. To improve production of huanglongbing (HLB) affected trees, nutrition, irrigation, and soil pH should be considered together, because each can influence the efficacy of the others in overcoming the effects of HLB on tree performance.

Citrus Leaf Sampling Procedures for Nutrient Analysis

Tripti Vashisth, Jamie D. Burrow, Davie Kadyampakeni, and Rhuanito S. Ferrarezi

Single-page guide to citrus leaf sampling procedures with additional suggestions for HLB-affected trees and guidelines for interpreting orange tree leaf nutrient analysis.

Management Options for Improving Flowering in Citrus Production

Leigh Archer, Miurel Brewer, Bikash Adhikari, Eduardo Esteves, Christopher Vincent, and Tripti Vashisth

In an era of both changing climatic conditions and huanglongbing (HLB), Florida growers are experiencing added challenges related to flower load and off-season flowering. Managing water stress, understanding the carbohydrate status of a tree, and utilizing chemical or hormone applications are all options for growers. In both commercial and backyard settings, these techniques can be employed to improve flowering and increase yield. These options are described in this article and should be considered as part of an integrated management plan to address low or irregular yields due to insufficient flowering or fruit set.

Huanglongbing (HLB; Citrus Greening) and Nutrient Deficiency Identification

Tripti Vashisth, Megan M. Dewdney, andJamie D. Burrow

Huanglongbing (HLB) is a bacterial disease that is spread by an insect, the Asian citrus psyllid. This 2-page fact sheet explains how to tell the difference between HLB symptoms and symptoms from nutrient deficiencies.

Use of Gibberellic Acid to Improve Health and Productivity of HLB-Affected ‘Valencia’ Trees

Tripti Vashisth

The goal of this publication is to provide the latest gibberellic acid (GA) use recommendation to Florida citrus growers. Recently, a multiyear field trial conducted on ‘Valencia’ has shown that GA applied monthly from September to January can improve yield of HLB-affected trees on average by 30% compared to untreated trees. Although GA treatment cannot eradicate the pathogen that causes HLB in affected citrus trees, the current GA application recommendation can provide growers an alternative remedy to alleviate HLB symptoms and ameliorate the production issues that are associated with the disease, including yield decline, reduced fruit size, increased preharvest fruit drop, and rapid tree health decline, until a cure for HLB or complete HLB-resistant cultivars can be developed.
