Soft rot or rhizome rot, caused mainly by Pythium, makes leaves yellow and wilt and the rhizome turns soft and watery, and it spreads fast in waterlogged soil. Prevention is far more effective than cure. Plant on raised, well drained beds and never let water stagnate, use only healthy disease free seed rhizomes and treat them with a recommended fungicide and bioagent like Trichoderma before planting, and follow crop rotation avoiding ginger after ginger. At first signs, remove and destroy affected clumps with surrounding soil and drench the patch and nearby plants with a recommended fungicide, and improve drainage immediately. Avoid moving soil or water from infected to clean areas. Confirm the current recommended seed treatment and drench with your KVK as products are updated.

Drainage is everything with this disease. My low patch that held water after rain was where the rot always started and spread out from. After I raised the beds higher and cut proper drainage channels, the problem dropped sharply.

Rotate the land and do not plant ginger after ginger. When I repeated ginger on the same plot the rot came back worse each year because the soil was already loaded with the fungus. Giving the field a break with other crops helped break that build up.

Catch it early and act on the same day. The first yellowing clump is the warning. When I waited it spread to the neighbours fast. Now I pull out the affected clump with the soil around it, take it off the field, and drench the spot as the KVK advised.

Do not carry soil or irrigation water from a rotted patch to a clean part of the field, that is how it travelled in my plot. I keep the affected corner separate and water it last so the runoff does not move the fungus into healthy beds.

Seed treatment before planting is the cheapest protection. I treat the rhizome pieces with a recommended fungicide and Trichoderma before they go in, following the dose on the label and what our KVK said. Combined with raised beds it has kept the rot down for me.
