How do I manage rhizome rot in organic ginger without chemical fungicides?

Rhizome rot, also called soft rot, is the biggest threat in ginger and harder to manage organically because you cannot use chemical fungicides, so prevention is everything. Use only healthy disease free seed from a clean field, treat seed with Trichoderma and Pseudomonas bio agents, and plant on raised beds with excellent drainage since standing water spreads the rot fast. Rotate ginger with non host crops and avoid replanting in a field that had rot last year. Apply well rotted compost and neem cake to build soil health and suppress soil pathogens, and remove and destroy any rotting clumps early so it does not spread. Mulch to protect rhizomes but keep beds from staying waterlogged. In organic ginger, clean seed plus drainage prevents more loss than anything you can apply later.
