Cultural Management
- ETL: 5-10 nymphs/leaf
- Avoid the alternate, cultivated host crops of the
white fly
- Adopting crop rotation with non-preferred hosts
such as sorghum, ragi, maize etc., for the white fly to check the build-up
of the pest
- Removal and destruction of alternate weed
hosts from the fields and neighbouring areas and maintaining field
sanitation
- Timely sowing with recommended spacing,
preferably wider spacing and judicious application of recommended dose of
fertilizers, particularly nitrogenous and irrigation management is
essential to arrest the excessive vegetative growth and pest build up.
- Late sowing may be avoided and the crop growth
should not be extended beyond its normal duration
- Field sanitation may be given proper attention.
- Cultivation of most preferred alternate host
crops like brinjal, bhendi, tomato, tobacco and sunflower may be avoided.
In case their cultivation is unavoidable, plant protection measures should
be extended to these crops also
- Monitoring the activities of the adult white
flies by setting up yellow pan traps and sticky traps at 1 feet height
above the plant canopy and also in situ counts
- Collection and removal of whitefly infested
leaves from the plants and those which were shed due to the attack of the
pest and destroying them
- Neem
seed kernel extract 5% (50 kg) and neem oil at 5 ml/l of water
- Fish oil rosin soap 25 kg at 1 kg in 40
lit of water
- Biological
control: Verticillium lecanii 1.15% WP 2500 g/ha
- In whitefly endemic areas, keeping yellow empty
tins smeared with greese as trap. Wipe out trapped whiteflies every day
and apply greese again.
