Active Ingredient and Mode of Action
Ulala features Flonicamid (50% WG), a member of the pyridinecarboxamide chemical class.
It acts on chordotonal stretch receptors in sucking insect sensory organs, causing irreversible paralysis of the stylet mouthparts.
Target insects are unable to pierce plant vascular tissues or ingest sap within thirty minutes of spray exposure, leading to eventual death by starvation.
- Formulation: 50 percent Water Dispersible Granules (WG)
- Feeding cessation: Stops sap feeding and honeydew production within thirty minutes
- Beneficial safety: High selectivity spares honeybees, predatory coccinellid ladybirds, and spiders
Registered Crop Applications and Pest Targets
Ulala is registered for managing difficult sap-sucking insect complexes that have developed resistance to neonicotinoids.
Its systemic translaminar movement enables effective protection of newly expanding foliage and dense lower canopies.
- Cotton: Controls whiteflies, aphids, and jassids (leafhoppers)
- Paddy: Highly effective against brown planthopper (BPH) and white-backed planthopper (WBPH)
- Chili and vegetables: Manages thrips and aphid complexes
Spraying Instructions and Stewardship
Apply Ulala when insect scouting confirms sucking pests crossing economic threshold levels.
Spray with adequate water volume using hollow cone nozzles, ensuring thorough wetting of the lower leaf surfaces where sucking pests feed.
Observe recommended pre-harvest waiting periods and practice IPM rotation with alternative chemical classes.
- Granule dissolution: Mix water-dispersible granules directly into the spray tank under mild agitation
- Resistance management: An ideal rotation partner to alternate with neonicotinoids and organophosphates
- Pre-harvest interval: Follow recommended label harvest intervals prior to crop harvesting

Common questions
What is the active constituent of Ulala insecticide?
Ulala contains Flonicamid 50% WG, a selective systemic sucking pest specialist.
Why do insects stop feeding quickly after spraying Ulala even if they do not drop immediately?
Flonicamid paralyses the insect mouthparts (stylet) via chordotonal organ disruption, stopping feeding within 30 minutes, leading to eventual starvation.
Is Ulala safe for honeybees and beneficial predators?
Yes, Flonicamid exhibits exceptional selectivity, making it safe for honeybees, spiders, and predatory ladybird beetles in IPM programs.
