Is this a Minor Pest?:

Yes

Minor Pest Title:

Nematodes (Meloidogyne spp., Pratylenchus brachyurus and Radopholus similis)

Minor Pest Description:

In some areas, nematodes reduce yields. Root-knot nematodes (Meloidogyne spp ) can be a problem in nurseries. Infested roots develop knots or galls. They later die and devoid of lateral roots. Affected plants show chlorosis and stunted growth.

Minor Pest What to do.:

Remove infested tea bushes, remove and replace large amounts of the soil.
Use nematode-free planting material.
To prevent infestation use plant-bags in the seedbed and use shade tree Indigoferra teismanii (Indigo tree) as a trap plant.
Also sow Guatemala grass (Tripsacum laxum) before starting a new plantation to suppress weeds, which could harbour nematodes.
Another important non-chemical method of control is the use of resistant or tolerant clones, if available .
Incorporation of neem cake into the soil is an effective management measure.
