Cauliflower (Brassica oleracea var. botrytis)

The young larvae mine epidermal surface of leaves producing typical white patches.
Later onwards, they feed externally making holes on the leaves and discolour with excreta.
Heavy infestations result in complete defoliation with only leaf veins remains.
Severely affected leaves are completely skeletonized.
The infestation is more in comparatively high temperature conditions.

Grow mustard as trap crop.
Install light traps.
Install pheromone trap to monitor DBM adults@ 5/ha and 25/ha for mass trapping.
Removal and destruction of plant debris after harvest and ploughing
Intercropping with tomato or carrot reduces the incidence.
Spray Neem seed kernel extract 5%.
Apply Bacillus thuringiensis formulation (1 gram/litre of water) or Neem Seed Kernal Extract (40 gram/litre of water) spray.
Conserve larval parasitoids viz., Cotesia plutellae in plains and Diadegma semiclausam in hills. Release 40,000 adults/ ac, five times@ 8,000 adults/release commencing from 20 days after planting.
Also encourage other parasitoids like Apanteles sicarius, Tetrastychus sokolowski (larval) Diadrumus collaris (larval pupal) and Brachymeria excarinata (pupal parasitoids).
