Ginger, Zingiber officinale
https://www.plantvillage.com/topics/ginger/infos
Ginger grows best in warm and sunny climates in a deep but well draining soil or loam that is high in organic matter The optimum soil pH for growth of ginger is between 6.0 and 6.5. The plant requires a minimum temperature of 15.5°C (59.9°F). Ginger is vegetatively propagated from small sections of the rhizome, called sets. Sets are produced by cutting a small 3–6 cm from a living rhizome and should be planted at a depth of 5–12 cm, leaving 15–35 cm between plants and 25–30 cm between rows. For optimal growth, the soil temperature at planting should not fall below 25°C(77°F). The rhizomes are harvested after the stems wither by digging them up carefully.
Ginger plants can be propagated from the rhizome (root) you would buy at the grocery store or you can find somewhere to purchase online. If using store bought root, you should soak the root in water for 24 hours before planting as sometimes the roots are sprayed with an anti-sprouting agent before they go on sale.
Ginger is vegetatively propagated from small sections of the rhizome, called sets (seehttps://www.plantvillage.com/topics/ginger/infos). Sets are produced by cutting a small 3–6 cm (1-2 in) section from the rhizome ensuring that each has at least one bud, which will produce the shoot. Air drying the set before propagation will help prevent fungal diseases.
If you wish to plant in the garden you can either plant directly or, if you live in a cooler climate, start the root indoors and produce transplants. This can be achieved by covering the sets with potting soil, manure or sawdust and keeping moist until the shoots of the new plants are 1-2 cm when they are ready to be moved into the garden.
Ginger can also be successfully grown in containers either indoors or out. You should plant the sets in a container that is at least 16 in wide and 12 in deep that has been filled with a good quality potting soil. Press the sets into the soil and lightly cover. It is important that the soil (and container) provide good drainage and you should keep the soil moist but not waterlogged and not let it it dry out.
Finally, ginger plants do not like direct sunlight so place the container in a partly shaded area.

Diseases
- Fusarium rhizome rot
- White fungus
- Bacterial soft rot (Erwinia sp.)
- Pythium
- Armillaria
- Big bud (bunchy top)
- Root-knot nematodes
Insect pests
- Cutworm
- Heliothis

- Symphilids
Pests of Ginger:
1) Shoot Borer: It prepares holes in the pseudo stem. Grass is thrown out of the holes and central shoot becomes yellow and withers.
Control: Spray 0.1% malathion at monthly interval from July to August.

Control: Spray 0.1% malathion at monthly interval from July to August.
2. Rhizome Flies: The maggots bore into rhizome and feed on it.
Control: Spray 0.05% methly parathion, 2 - 3 times from July onwards.
Control: Spray 0.05% methly parathion, 2 - 3 times from July onwards.
3. Leaf Roller: The caterpillar feeds from within the leaf by folding it.
Control: Spray 0.05 % dimethoate.
4. Scales: They suck sap from rhizomes and cause them to shrive! and dry up.
Control: Dip the rhizomes in 0.05 % dimethoate at planting.
Diseases of Ginger:
Control: Spray 0.05 % dimethoate.

Control: Dip the rhizomes in 0.05 % dimethoate at planting.
Diseases of Ginger:
1. Soft -Rot: It is- the most - destructive- -disease causing total loss of affected clumps. Light yellowing of tips of lower leaves spreads downwards to leaf blades. It spreads to all leaves of plant and is followed by drooping, withering and drying. Rotting spreads to rhizomes from collar region of stem. Disease spreads from seed, rhizomes and soil.
Control:
a) Provide proper drainage.
b) Select disease-free rhizomes for sowing.
c) Treat seed rhizomes with 03 % Dithane M -45 for 30 minutes before storage and before planting.
d) Drench the beds with same fungicide or Captafol @ 0.1 %.
2) Leaf Spot: Small oval or elongated spots with white centre and dark brown margin develop on leaves.
Control: Spray 1 % Bordeaux mixture.

Common Pests and Diseases
Bacterial soft rot
| Symptoms | Cause | Scientific name | Comments |
|---|---|---|---|
| Light yellow lower leaf tips; yellow leaves; drooping, withered leaves | Bacteria | Erwinia spp. | Favors water logged fields |
Bacterial wilt
| Symptoms | Cause | Scientific name | Comments |
|---|---|---|---|
| Yellowing and wilting of lower leaves; wilting shoot; gray or brown discoloration on underground stem; slimy ooze | Bacteria | Pseudomonas solanacearum |
Fusarium yellows (Rhizome rot)
| Symptoms | Cause | Scientific name | Comments |
|---|---|---|---|
| Stunted plant growth; yellow leaves and stems; brown discoloration of water conducting tissue within stem | Fungus | Fusarium oxysporum | Disease favors warm, moist soils |
Pythium soft rot
| Symptoms | Cause | Scientific name | Comments |
|---|---|---|---|
| Yellowing leaves; soft rotting of the underground stems (rhizomes) | Fungus | Pythium graminicola | Disease favors warm temperatures and high rainfall |
Pythium myriotylum, responsible for a severe rhizome rot. Symphylids are wingless soil inhabiting arthropods which feed on root tips of the ginger plant and impair the plants´ ability to absorb nutrients thus seriously restricting plant growth and development. Damage caused by symphylids to ginger roots is also expected to facilitate entry ofPythium into the plant.
Chinese rose beetle
| Symptoms | Cause | Scientific name | Comments |
|---|---|---|---|
| Holes in leaves; entire leaf consumed with the exception of the leaf veins | Insect | Adoretus sinicus | Adult beetle red to brown in color |
Root-knot nematode
| Symptoms | Cause | Scientific name | Comments |
|---|---|---|---|
| Water soaked lesions on roots | Nematode | Meloidogyne spp. |
