27. Management practices
• Adopting crop rotation with non-preferred hosts such as
sorghum, ragi, maize etc.,
• Removal and destruction of alternate weed hosts.

not be extended
• Cultivation of most preferred alternate host crops like
brinjal, bhendi, sunflower may be avoided
• Set up yellow pan traps and sticky traps @ 12/ ha

28. Spray any one in early stage (500 L fluid/ha)
•Methyl demeton 25 EC 500 ml or
•phosphamidon 40 SL 600 ml/ha
Spray any one in mid/late stages (1000 L liquid/ha)
Phosalone 35 EC at 2.5 l/ha
Quinalphos 25 EC at 2.0 l/ha
Monocrotophos 36 SL 1.25 l/ha
Triazophos 40 EC 2.0 l/ha
