Control
a) Technical culture

- Sorting rhizomes before planting;
- Strive for healthy plant growth, free from wilt disease or other diseases;
- The use of patchouli as a barrier and intercropping it with ginger can reduce the population of rhizome flies;
- Sanitation by cleaning the plant from plant debris and destroying it.
b) Biological
Utilizing natural enemies, namely larvae-pupa parasitoid Trichopria sp. (Diapriidae, Hymenoptera), and the fungus Beauveria bassiana which infects larvae.
c) Chemical
Use of insecticides to control adult flies. Insecticide that is registered and permitted by the Ministry of Agriculture for ginger pests.
