Cultural Control
# The crop sown before 20th October escape
the damage.
# Apply recommended dose of
fertilizers.
Mechanical Control
# Destroy the
affected parts along with aphid population in the initial stage.
Biological Control
# Ladybird beetles
viz., Cocciniella septempunctata, , Hippodamia variegata and cheilomones
vicina are most effcient pradators of the mustard aphid. Adult beetle may
feed an average of 10 to 15 adults/day.
# Several species
of syrphid fly i.e., Sphaerophoria spp., Eristallis spp., Metasyrphis spp., Xanthogramma
spp and Syrphus spp. are predating on aphids.
# The lacewing, Chrysoperla carnea
predates on the mustard aphid colony.
Chemical Control
# Spraying should be done at ETL
level.
# Spraying should be done in evening
time.
# Spray the crop
with one of the following insecticides in the aphid appearance; Imidacloprid
17.8% @ 0.25 ml/l,Thiamethoxam 25 WG @ o.2g/l, Dimethoate 30EC @ 1 ml/l of
water
