Description:

• Aphid infestations are typically observed in the early growing stages, particularly during hot weather.

Damage Symptoms:

• Aphids suck the cell sap from the leaves, causing them to curl and distort.
• Aphids excrete honeydew, which results in sooty mould formation on the leaves, preventing sunlight penetration and reducing photosynthesis.
• Stunted growth and poor ear formation occur, and the plant becomes considerably weakened due to sap-sucking by aphids.
• Aphids serve as a vector for maize dwarf mosaic virus, leading to increased crop loss.

Preventive Measures:

• Introduce natural predators like ladybugs and lacewings.

Control Measures:

• Apply imidacloprid (0.5 ml/l) or thiamethoxam (0.25 g/l).
