Active chemistry and feeding-disruption mechanism
Flonicamid represents a unique mode of action distinct from neonicotinoids and organophosphates.
- Chordotonal Organ Modulator: Selectively disrupts TRPV channels in insect chordotonal stretch receptors.
- Rapid Feeding Cessation: Sucking insects cease feeding within 30 minutes, immediately halting crop sap drainage.
- Starvation Mortality: Affected nymphs and adults die from irreversible starvation over 2 to 3 days.
- Excellent Safety for Pollinators: Exhibits favorable safety margins for honeybees, predatory mites, and parasitic wasps.
Target crops and approved pest spectrum
Registered under CIBRC standards for major Indian commercial and horticultural cropping systems.
- Cotton: Aphids, jassids (leafhoppers), and whiteflies.
- Rice (Paddy): Brown plant hopper (BPH) and white-backed plant hopper (WBPH).
- Chilli: Yellow mites and thrips.
- Vegetables: Whiteflies and aphids in tomato, okra, and cucurbits.
Application guidelines and resistance stewardship
Adhering to proper spray calibration ensures maximum biological efficacy and prevents resistance.
- Apply at the earliest sign of pest infestation before populations reach epidemic proportions.
- Use clean water and calibrate knapsack or power sprayers for complete canopy coverage.
- Rotate with alternative chemistries to ensure sustainable resistance management in whiteflies and plant hoppers.
- Observe the approved pre-harvest interval (PHI) printed on the commercial package label.

Common questions
What is the active molecule in Ulala insecticide?
Ulala contains Flonicamid 50% WG, a selective systemic insecticide in the pyridinecarboxamide chemical group.
How does Ulala differ from conventional insecticides?
Unlike neurotoxic chemicals that cause rapid twitching and knockdown, Ulala paralyzes feeding organs so insects starve without feeding on the crop.
Is Ulala effective against sucking pests resistant to neonicotinoids?
Yes, because Flonicamid belongs to IRAC Group 29 with no known cross-resistance to neonicotinoids or organophosphates, it controls resistant sucking pests effectively.
