I asked what happened? Engr Canuto, Owner of Ephratah Farms provided me substantial information and advice on what to do -
Quite a challenge for me since I am not a real Farmer. I just dream of becoming a Farmer...realizing how challenging it is.
Here are concrete information I learned from AI. This is enlightening for me :)
Dragon Fruit Diseases -
TastyLandscape
Dragon fruit face fungal, bacterial, and viral issues, with common culprits including Anthracnose, Stem Canker (Neoscytalidium), Fruit & Stem Rot (Bipolaris), Cactus Virus X, and fungal rusts (like Botryosphaeria), often appearing as brown spots, lesions, or rotting, worsened by excess moisture or poor hygiene, necessitating fungicide, sterile tools, and proper cultural care.
Common Diseases
Anthracnose:
Fungal disease causing sunken, circular, reddish-brown spots with light centers on stems and fruit.
Stem Canker/Brown Spot:
Fungal (e.g., Neoscytalidium dimidiatum, Bipolaris cactivora) causes brown to black lesions, canker, and rot, often from wounds or stress.
Bacterial Soft Rot:
Bacteria (like Enterobacter or Xanthomonas) cause stems to soften, yellow, and rot, often from overwatering.
Cactus Viral Disease: Cactus Virus X causes mottling (mosaic patterns) on branches, affecting plant health.
Rusts:
Fungal infections (e.g., Botryosphaeria dothidea) create red/brown spots, sometimes like bull's-eyes, often linked to stress.
Causes & Risk Factors
Overwatering/Poor Drainage:
Leads to root rot and bacterial/fungal issues.
Unsterile Tools:
Spreads fungal spores and bacteria.
Wounds/Stress:
Creates entry points for pathogens.
High Humidity/Rain:
Encourages fungal growth.
Management & Prevention
Cultural Practices:
Ensure good airflow, avoid waterlogging, use well-draining soil, and sterilize pruning tools with alcohol.
Physical Removal:
Prune and destroy infected branches immediately.
Fungicides:
Copper-based fungicides or specific chemical treatments (mancozeb, carbendazim) can control fungal issues.
Temperature Control:
Storing fruit at cool temperatures (around 6Β°C) can reduce storage rots.
