Chemical Class and Selective Feeding Blocker Action
Flonicamid belongs to the pyridinecarboxamide chemical class (IRAC Group 29 - Chordotonal organ modulators). It acts by modulating insect chordotonal stretch receptor organs, disrupting coordination and tactile sensory mechanics.
Within 30 minutes of contact or ingestion, the insect's stylet mouthparts become paralyzed. The pest ceases feeding immediately, stops honeydew excretion, and eventually dies of starvation and dehydration over 2 to 3 days without causing further plant damage.
- IRAC Group 29 Mode of Action: Immediate feeding cessation through chordotonal organ modulation.
- Systemic and Translaminar Movement: Absorbed rapidly by leaves and translocated acropetally to protect newly expanding leaves and shoots.
- Water Dispersible Granules (WG): Dust-free granules that dissolve rapidly in water without nozzle clogging.
Target Pests and Crop Spectrum
Ulala is officially registered under CIBRC standards for controlling critical sucking insect complexes in cotton and paddy (rice). In cotton, it manages whiteflies (Bemisia tabaci), jassids (leafhoppers), and aphids.
In rice crops, it provides control against brown planthopper (BPH - Nilaparvata lugens) and whitebacked planthopper (WBPH), preventing hopper burn and halting the transmission of damaging plant viral diseases.
- Cotton Whitefly Management: Halts feeding of both nymphs and adult whiteflies.
- Paddy BPH Protection: Controls brown planthoppers at the base of rice tillers, preventing hopper burn.
- Virus Vector Suppression: Immediate stylet feeding cessation stops the transmission of viral pathogens like cotton leaf curl virus.
Application Guidelines and IPM Safety Profile
Apply Ulala at the first appearance of sucking pests or when populations reach economic threshold levels (ETL). Use calibrated knapsack sprayers fitted with hollow cone nozzles, ensuring thorough spray penetration into the lower and middle canopy.
Ulala exhibits an exceptional safety profile toward beneficial arthropods, natural predators (such as ladybird beetles, lacewings, and spiders), and pollinators like honeybees, making it a cornerstone for Integrated Pest Management (IPM) programs.
- Targeted Safety: Highly selective mode of action with minimal impact on beneficial pollinators and predatory insects.
- Rainfast Property: Absorbed into leaf cuticles within 2 to 3 hours, offering rainfast protection.
- Pre-Harvest Interval (PHI): Comply strictly with crop-specific harvest waiting periods on the registered product packaging.

Common questions
What is the technical ingredient in Ulala insecticide?
Ulala contains Flonicamid 50% WG (Water Dispersible Granules), a pyridinecarboxamide-class insecticide.
How does Ulala kill sucking pests like whitefly and BPH?
It paralyzes the insect's mouthparts (stylet) by modulating chordotonal organs within 30 minutes, causing irreversible feeding cessation and starvation.
Is Ulala safe for honeybees and beneficial insects?
Yes, Flonicamid possesses high selectivity and displays minimal toxicity toward honeybees, predatory spiders, and ladybird beetles when used per label directions.
