Description:

• Adult aphids are light green in color but appear grey due to a white powdery substance covering their body.
• Nymphs are yellowish-green.
• The pest primarily infects the crop during late autumn to early spring.

Damage Symptoms:

• Both nymphs and adults infest terminal shoots and suck sap from the plant.
• They excrete honeydew, leading to the formation of sooty mold.
• The damage results in the devitalization of plants and causes twisting of leaves and young shoots.

Preventive Measures:

• Introduce natural predators such as Coccinellids and green lacewings.

Control Measures:

• Apply a foliar spray of dichlorvos at 1 ml/l, monocrotophos at 1.6 ml/l, methyl demeton at 2 ml/l, or dimethoate at 2 ml/l.
