How to Control Cauliflower Diamondback moth

For the prevention of diamondback moth, bold mustard should be sown in 2 lines after every 25 lines of cabbage/Cauliflower.
Spray the crop with Profenofos 50% EC 500 ml/acre or Profenofos 40% EC + cypermethrin 4% EC @ 400 ml/acre or
Spinosad 25% SC100 ml/acre or Indoxacarb @ 300 ml/acre or Emamectin Benzoate 5% SG @ 100 gm/acre Spray at fortnight intervals starting from 25 days after transplanting to control the pest.

The seeds are sown in the nursery bed. Raised beds of size 3*6 m. and 10-15 cm. in height are prepared.
About 70 cm. distance is kept between two beds to carry out intercultural operations.
The surface of nursery beds should be smooth and well leveled.
Well decomposed FYM @ 8-10 kg/square meter should be added at the time of bed preparation.
Raised beds avoid the problem of water logging in heavy soils.
To avoid mortality of seedlings due to damping off, drench the beds three weeks before sowing with carbendazim 50% WP @ 15-20 gm/ 10 liter of water. OR Apply Thiophanate Methyl 70% WP @ 0.5 gram/meter2
To avoid mortality of seedlings due to insect attack, Apply Thiamethoxam 25% WG @ 0.3 gram/meter2

Cultivation of cauliflower is done mainly on sandy to heavy soil rich in organic matter.
Light soil is preferred for early crops.
On heavy soil, plants grow more slowly and the keeping quality is improved.
The optimum pH is 6-7 and liming is required when pH is below 5.5.
Plants growing in saline soils are prone to fungal and bacterial diseases.

Healthy seed should be selected for sowing.
The seed should be treated with Carboxin 37.5% + Thiram 37.5% WP @ 2g/kg of seed before sowing.
Continuous raising of nursery in the same plot should be avoided.

The cabbage seeds are sown in a seedbed and 4-6 week old seedlings are transplanting to the field.
Raised beds of size 3 x 0.6 m and 10-15 cm in height are prepared.
About 70 cm distance is kept between two beds to carry out intercultural operations such as weeding, etc.
The surface of beds should be smooth and well levelled.
Well-decomposed FYM @ 8-10 kg/square m is added at the time of bed preparation.
Raised beds are necessary to avoid the problem of water logging in heavy soils.
To avoid mortality of seedlings due to damping off, drenching of the beds with Thiophanate Methyl 70% WP @ (30g/15 litres of water) is effective.

Suitable Climate and soil for Cabbage Cultivation:-

In India, cabbage is grown in large areas having a cool and moist climate.
A temperature range of 15- 21°C is considered as optimum for growth and head formation of the crop.
Cultivation of cabbage is done mainly on sandy to heavy soils rich in organic matter.
Early crops prefer light soil while late crops thrive better on heavier soils due to retention of moisture.
On heavy soils, plants grow more slowly and the keeping quality is improved.
A pH range of 6.0-6.5 is considered as optimum for growing cabbage.
Plants growing in saline soils are prone to diseases.
