Romeo
1.
2. Common Name :Novaluron 10% EC
Chemical Group :Benzoyl Phenyl Urea (BPU)
Mode of Action :Chitin Synthesis Inhibitor (CSI)
:Insect Growth Regulator (IGR)
Moulting :Process of shedding of old skin (cuticle) in
immature stages at intervals
Cuticle :made of chitin (structural component)
which gives hardening effect to larvae
Moulting is important for growth & development
3. Romeo is a host-specific insect growth regulator and
chitin synthesis inhibitor
IGR are comparatively safer to beneficial insects and
environment and are compatible for use in an integrated
pest management system.
Romeo affects only at the larval stages while the adults are
seldom damaged.
Research says Romeo efficiently controls Lepidopterans,
Coleopterans and Homopterans by both ingestion and
contact activity.
4. Interfere with chitin synthesis in larval stages
Stomach poison with low contact activity - Larvae
have to feed treated plant parts
Arrest feeding :2-3 hours after feeding
Mortality :2-3 days
Latent effects :
Deformed pupae
Deformed adults
Larval-pupal intermediate
Pupal-adult intermediate.
5. Crop Common name of the pest Dosage /Acre
Cotton Spodoptera 400
Cabbage Diamond Back Mouth 300
Tomato Spodoptera / Fruit borer 300
Chilli Fruit borer, Tobaco Caterpillar 150
Bengal Gram Pod Borer 300
6. Life cycle 25 – 30 days.
depending on weather, with a range of
about 17 to 51 days.
Damage:-
Plant damage is caused by larval
feeding.
the larvae are very small, they can be
quite numerous, resulting in complete
removal of foliar tissue except for the
leaf veins.
This is particularly damaging to
seedlings, and may disrupt head
formation in cabbage, broccoli, and
cauliflower.
Major Pest:-Diamond Back Moth
7. It is a major pest of tomato widely
distributed in tropics, subtropics and
warmer temperate regions of the world.
Eggs are laid singly, generally on leaves and
flowers in the upper canopy of the plant.
A female lays approximately 500 eggs, on
hatching the young caterpillars feed on
tender foliage, advance stage caterpillars
attack the fruits.
One caterpillar is capable of destroying 2-8
fruits.
8. Right time of application
based on ETL
Right stage of insect
first & second instars
Right crop stage.

due to stomach activity.
