Bakanae disease is caused by a fungus known as Gibberella fujikuroi.
This fungal pathogen infects rice plants, leading to a variety of symptoms, including abnormal elongation of seedlings (hence the name "bakanae," which means "foolish seedling" in Japanese), reduced tillering, and eventual death of the plant. The Gibberella fujikuroi fungus produces gibberellins, plant hormones that stimulate excessive growth.
Here's a breakdown:
- Causative Agent: Gibberella fujikuroi (a fungus).
- Mechanism: The fungus produces gibberellins, causing rapid and abnormal plant growth.
- Impact: Reduced yield and potential crop loss in rice cultivation.
