Chemical Class and Neurotoxic Mode of Action
Tatamida provides reliable protection against elusive sap-feeding insect populations.
Key biochemical attributes:
- Active ingredient: Imidacloprid formulated as a soluble liquid at 17.8% SL concentration.
- Chemical class: Neonicotinoid insecticide (IRAC Group 4A).
- nAChR receptor binding: Acts as an agonist on post-synaptic nicotinic acetylcholine receptors, disrupting nerve impulse transmission.
- Xylem systemic movement: Absorbed rapidly by plant foliage and roots, moving upward through xylem vessels to defend newly emerging leaves.
- Extended residual action: Protects crops against sucking pests for multiple weeks, reducing the frequency of field applications.
Target Crops and Sucking Pest Complex
Tatamida 17.8% SL is registered under CIBRC guidelines across key commercial, cereal, and horticultural crops.
Major registered crop uses:
- Cotton: Controls aphids, jassids, and thrips, preventing leaf crinkling and shedding of young squares.
- Paddy (Rice): Highly effective against brown planthopper (BPH) and white-backed planthopper (WBPH) when sprayed at the base of hills.
- Chilli and Tomato: Suppresses thrips and whiteflies, preventing the transmission of destructive leaf curl viruses.
- Sugarcane: Applied to control Pyrilla leaf hoppers and sucking bug complexes.
Application Guidelines, Mixing and Safety
Proper application ensures maximum translaminar uptake while protecting beneficial pollinators.
Safe spraying guidelines:
- Dosage compliance: Measure strictly per manufacturer label instructions using clean, neutral water.
- Pollinator protection: Avoid spraying during peak morning hours when honeybees are actively foraging on crop blossoms.
- Resistance rotation: Rotate imidacloprid with alternative chemical classes (such as flonicamid or pymetrozine) to manage resistance.
- Operator safety: Wear personal protective equipment including chemical-resistant gloves, eye goggles, and a protective mask during mixing.

What is the active chemical ingredient in Tatamida insecticide?
Tatamida contains Imidacloprid 17.8% SL, a broad-spectrum systemic neonicotinoid insecticide.
Which major pests are controlled by Tatamida in rice and cotton?
It controls brown planthoppers (BPH) in rice and aphids, jassids, and thrips in cotton crops.
Why is imidacloprid effective against virus-transmitting sucking pests?
It causes rapid feeding cessation within minutes of ingestion, stopping whiteflies and thrips from transmitting viral plant pathogens.
