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.
