COMMON PEST IN GERBERA:

Aphids:

Identification: Small, pear-shaped insects found on new growth, stems, and leaves. They can be green, black, or yellow.

Damage: Cause distorted growth, yellowing leaves, and produce sticky honeydew which attracts sooty mold.

Management:

Use insecticidal soap or neem oil

.

 

 

Introduce natural predators like ladybugs and

Regularly wash plants with water to remove.

 Whiteflies:

Identification: Tiny, white, moth-like insects that flutter around when the plant is disturbed.

Damage: Cause yellowing and wilting of leaves, and secrete honeydew which leads to sooty mold.

Management:

Use yellow sticky traps to monitor and reduce population.

Apply insecticidal soap or horticultural oil.

Introduce parasitic wasps (Encarsia formosa).

Spider mite:

Identification: Tiny, spider-like creatures often found on the undersides of leaves. Leaves may show tiny yellow or white speckles.

Yellow sticky traps can capture adult flies.

Summary:

Effective strategies of management which includes cultural practices, biological, chemical control.Which increases yiled in gerbara.
