Diamondback Moth

Cauliflower

Name: Diamondback Moth

Scientific Name: Plutella xylostella

Crop: Cauliflower

Description:

  • Diamondback moth infestations often occur when cauliflower plants are still young and during late winter and early spring.
  • The pest easily moves from one crop to another by flying or being carried by the wind.

Damage Symptoms:

  • The young larva feeds on the lower surface of the leaves, creating small irregular holes that eventually enlarge.
  • Severe feeding causes significant damage to the leaves, reducing the plant's photosynthesis ability and slowing its growth.
  • The larvae are destructive to the growing tip and, in cases of severe infestation, may lead to the death of the plant.

Preventive Measures:

  • Plant trap crops and remove them before the pest infests cauliflower.
  • Practice crop rotation.

Control Measures:

  • Apply Spinosad (0.25 ml/l) to control larvae at 15 and 30 DAS.
  • Use biological control methods such as Trichogramma or Encarsia wasps to manage the moth population.
