- 3 min reading time
Ginger, a pungent and versatile spice, is a vital part of Indian cuisine. However, cultivating this flavorful treasure can be a battle against pests and diseases. Here, we explore some major threats to Indian ginger farms and how to manage them for a healthy harvest.
1 Bacterial foes:
- Bacterial wilt (Ralstonia solanacearum): Nicknamed "prel rog," this disease causes wilting, yellowing, and stunting of plants. The bacteria live in the soil and enter through wounds.
Management:
- Crop rotation with non-susceptible crops like turmeric or pulses.
- Use disease-free seeds or rhizomes.
- Soil treatment with copper fungicides before planting.
- Once the disease is noticed in the field all beds should be drenched with Streptocycline Or Multiplex Bactinash
2. Fungal Felons:
- Soft rot (Pythium aphanidrematum): Also known as "paheli," this fungal disease causes yellowing leaves, rotting rhizomes, and a foul odor. It thrives in waterlogged conditions.
Management:
-
Ensure proper drainage to avoid waterlogging.
-
Practice crop rotation and solarization (covering soil with plastic sheets for heat treatment).
-
Drenching the soil with Bordeaux mixture can help control the spread.
-
Dry rot (Fusarium and Pratylenchus complex): This fungal-nematode combo causes shrinking and shriveling of rhizomes, with internal discoloration.
- Recommended products : For seed treatment or drenching - Sprint 2.5gm + Multiplex Bactinash, 0.5gm+ Ekalux 2ml per liter of water. Or Anshul Tricomax / Multiplex Nisarga
- Use disease-resistant ginger varieties.
- Hot water treatment of seeds before planting.
- Applying neem cake or bio-pesticides can help manage nematodes.
3. Spot the Spots:
- Leaf spot/blight (Phyllostricta zingiberi): This fungal disease manifests as small, brown spots with yellow halos on leaves, reducing their photosynthetic capacity.
Management:
- Planting ginger under partial shade can help.
- Spraying Bordeaux mixture at regular intervals during the initial stages of the disease is effective.
- Recommended products: Sprint, Anshul Tricomax / Multiplex Nisarga, Ekalux
