The Difference

Huanglongbing (HLB) is a bacterial disease that is spread by an insect, the Asian citrus psyllid. This two-page fact sheet, which is best viewed as a PDF, http://edis.ifas.ufl.edu/pdffiles/PP/PP32800.pdf, explains how to tell the difference between HLB symptoms and symptoms from nutrient deficiencies. Written by T. Vashisth, M.M. Dewdney, and J.D. Burrow and published by the Plant Pathology Department. http://edis.ifas.ufl.edu/pp328

The majority of plant health problems categorized as plant diseases are caused by microorganisms. As the name implies, these are extremely tiny disease agents that ordinarily require a microscope to be seen. The very minute size of these disease-causing pathogens accounts for the mystery that often surrounds their presence and impact in the garden. The pathogenic microorganisms that attack garden vegetables, including pepper, can be classified into three major groups: fungi, bacteria, and viruses. This document is Fact Sheet PP-201, one of a series of the Plant Pathology Department, Florida Cooperative Extension Services, Institute of Food and Agricultural Sciences, University of Florida.

Citrus Leaves

Citrus Greening, which is mainly caused by bacteria, is one of the severe citrus diseases affecting all citrus cultivars and causing the deliberate abolition of trees worldwide. This infectious disease cannot be spread by wind, rain, or contact by contaminated personnel. The primary vector that spreads this disease through feeding citrus leaves is the Asian citrus psyllid (ACP), a minuscule insect. The management of citrus greening is also very costly as there is no fruitful technique is developed to cure this disease except removing all infected plants from good ones to eliminate the dissemination of the pathogen. Citrus greening identification is also the most difficult job, as the symptoms are similar to other citrus diseases and nutrient deficiency. Asymmetrical blotchy mottling patterns on leaves are the main symptoms to detect this disease. Here we have discussed some visual signs of citrus greening, which will ultimately help root level farmers to identify and prevent this disease before it drastically impacts citrus plants. Whether it is affected by citrus greening or lack of nutrients, we have also discussed the pen test method of determining the symptoms as symmetrical or asymmetrical across the mid-vein.
