Description:

• Nematodes infest the roots of the plant, forming root galls that affect nutrient absorption. In cases of heavy infestations, yield loss may be up to 60%.

Damage Symptoms:

• The roots exhibit galls or swellings, which inhibit the plant's ability to absorb nutrients.
• The plant's height is stunted, with yellowing leaves and reduced vigour.
• In dry weather, premature wilting and decreased fruit setting occur.
• Even with adequate water and nutrition, plants show poor growth and development.

Preventive Measures:

• Practice crop rotation with non-host crops.
• Deep ploughing of the soil during summer.

Control Measures:

• Apply neem cake to the soil.
• Soil fumigants or bio-nematicides can be applied.
