Chemical management
- Spray
any one of the following plant products alone or in combination with the
recommended dose of insecticide (at 2 ml/l of water)
-Acetamiprid20% SP 100 g/ha
-Chlorpyriphos 20% EC 1250 ml/ha
- In the
early stages with high volume sprayer, use a gooseneck nozzle to cover the
under surface of the foliage to get good control of the pest. If high volume
sprayers are not available, 375 litres of spray fluid may be used per hectare
for application in the low volume motorised knapsack mist blower
- The use of
synthetic pyrethroids should be discouraged in cotton to avoid the problem of
whitefly
- Fenvalerte and deltamethrin cause resurgence of whiteflies, so avoid repeated spraying of pyrethroids
- The plant
protection measures should be adopted on a community basis in a specified
cotton area
