Unique Chemistry and Feeding Cessation Mechanism
Ulala features Flonicamid (pyridinecarboxamide class), which belongs to a unique IRAC mode of action group (Group 29).
It targets chordotonal stretch receptor organs in sucking insects, causing irreversible inhibition of stylet insertion and salivation.
Treated aphids, jassids, and whiteflies cease crop sap feeding within half an hour and starve to death over several days.
- Active ingredient: Flonicamid 50 percent WG (Water Dispersible Granules)
- Rapid feeding cessation: Stops sap feeding and honeydew secretion within thirty minutes
- Beneficial safety: Highly safe for honeybees, predatory coccinellid ladybirds, and lacewings
Target Pests and Approved Field Crops
Ulala is registered for managing difficult sap-sucking pest complexes that have developed resistance to neonicotinoids.
Its systemic translaminar movement enables effective protection of newly emerging leaves and dense lower canopies.
- Cotton: Controls whiteflies, aphids, and jassids (leafhoppers)
- Paddy: Effectively suppresses 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.
- 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.
