Citrus Greening (Huanglongbing): Bacterial Infection | How to Treat
Citrus Greening is the most serious disease in global citrus production. Caused by a bacterium transmitted by the psyllid insect, it attacks the plant's vascular system, preventing the circulation of nutrients. There is no cure for infected plants, and management focuses on the removal of diseased plants and the control of the insect vector.

Citrus Greening (Huanglongbing) is a bacterial disease with critical severity that spreads at a fast rate. Recovery typically takes approximately 30 days with proper treatment. This condition is contagious and can spread between plants.
Citrus Greening (Huanglongbing) has no effective chemical cure, unlike pests. Without removing affected parts, the infection spreads internally through the plant. Without isolation, nearby plants can become infected within days.

Bacterial Leaf Spot
MediumBacterial leaf spot is a plant disease caused by bacteria in the Xanthomonas and Pseudomonas genera that affects various ornamental and edible plants. The bacteria infect leaves through wounds or natural openings, causing characteristic lesions that can lead to premature leaf drop and plant weakening.
Bacterial Soft Rot
HighBacterial soft rot is a destructive plant disease caused primarily by bacteria from the genera Pectobacterium (formerly Erwinia) and Dickeya. These bacteria produce enzymes that break down plant cell walls, causing rapid and foul-smelling tissue decomposition. It mainly affects succulent tissues such as tubers, fruits, stems, and bulbs, being especially problematic in warm and humid conditions.
Fire Blight
CRITICALFire blight is a highly destructive and contagious bacterial disease caused by Erwinia amylovora. It primarily affects plants in the Rosaceae family, including apple, pear, quince trees, and various ornamental plants. The disease can destroy an entire orchard in a single growing season under ideal conditions, with the bacterium moving approximately 11 inches per week in new growth.
Crown Gall
HighCrown gall is a bacterial disease caused by Agrobacterium tumefaciens that affects over 140 species of plants. The bacteria insert DNA into plant cells, causing them to divide uncontrollably and form large tumor-like growths (galls) primarily on roots, stems, and at the soil line. These galls restrict water and nutrient flow, severely impacting plant health and potentially killing the plant.
