Pests

Whiteflies on Basil

Commonly affects: Ocimum basilicum (Basil)

Tiny white, moth-like insects fly up in a small cloud when the plant is disturbed, and can be found clustered on the underside of leaves. Affected foliage may develop sticky honeydew residue and a general lack of vigour.

Potential Causes

  1. 1Warm, humid conditions, especially in greenhouses or indoor growing setups
  2. 2Introduction from a nearby infested plant
  3. 3Overcrowded plantings providing ideal breeding conditions

Solution Steps

  1. 1Use yellow sticky traps near the plant to catch and monitor adult whitefly populations.
  2. 2Spray the underside of leaves thoroughly with insecticidal soap or neem oil, repeating every 5�7 days.
  3. 3Isolate heavily infested plants from other herbs and vegetables to prevent further spread.
  4. 4Improve airflow around the plant, since whiteflies thrive in still, humid conditions.

Prevention Tip

Inspect the underside of leaves regularly, especially on indoor or greenhouse-grown basil, since whiteflies can build up unnoticed until populations are already significant.
