Mode of action and target pests
Flonicamid acts as a chordotonal organ TRPV channel modulator. It disrupts the insect's nervous perception of hunger, preventing nymphs and adults from piercing plant tissues.
- Aphids and jassids (leafhoppers) in cotton and horticultural crops.
- Whiteflies and thrips in chilli, tomato, and vegetables.
- Brown plant hopper (BPH) and white-backed plant hopper (WBPH) in paddy.
- Favorable safety profile for beneficial pollinators and predatory insects when applied as directed.
Application practices and label guidelines
Ulala is formulated as water-dispersible granules (WG) that dissolve evenly in water. Farmers must adhere strictly to the Central Insecticides Board & Registration Committee (CIBRC) approved dosage and pre-harvest intervals printed on the commercial package.
- Spray early in the pest infestation cycle when sucking insects reach economic threshold levels.
- Use clean water and a knapsack or motorized sprayer fitted with a hollow cone nozzle for thorough foliar coverage.
- Observe the mandated pre-harvest interval (PHI) between the final spray and harvesting.
- Rotate with alternate chemical groups to prevent resistance development in sucking pest populations.
Safety and handling precautions
Proper personal protective equipment (PPE) must be worn during chemical handling and field spraying.
- Wear chemical-resistant gloves, a face mask, and eye protection while measuring and mixing.
- Avoid spraying during windy conditions or during the hottest midday hours.
- Triple-rinse empty containers and dispose of them safely in accordance with environmental regulations.
