Chemical profile and chloride channel mode of action
- Avermectin class: Active ingredient Abamectin at 1.9% concentration (IRAC Group 6 / Glutamate-gated Chloride Channel Allosteric Modulator).
- Neuromuscular paralysis: Stimulates the continuous release of gamma-aminobutyric acid (GABA) and binds to glutamate-gated chloride channels; target mites and thrips cease feeding immediately and die within 2 to 4 days.
- Translaminar leaf reservoir: Rapidly penetrates leaf cuticles and forms a stable chemical reservoir inside leaf mesophyll tissues, shielding the active ingredient from rain wash-off and photodegradation.
- Low surface residue: Unabsorbed surface residues break down rapidly in sunlight, providing safety to beneficial predators like ladybird beetles and predatory mites.
CIBRC approved target crops and pests
Approved in Indian agriculture for managing Two-spotted spider mites (Tetranychus urticae) and Thrips in grapes; Yellow mites and Thrips in chilli; Red spider mites in brinjal; and Leaf miners (Liriomyza spp.) in tomato and cucumber. In polyhouses and export grape vineyards, Abamectin is indispensable for managing stubborn mite infestations.
Application guidelines, dosage and safety
- Follow CIBRC approved label dosages strictly (typically 150 to 200 ml per acre in 200 liters of water for field crops).
- Apply at the early onset of mite webbing using a fine hollow cone nozzle for thorough foliar wetting.
- Observe the mandatory Pre-Harvest Interval (PHI) printed on the container label before harvest.
- Wear personal protective gear and avoid spraying during high wind conditions.

Common questions
What is the biological origin of Abamectin insecticide?
Abamectin is a natural fermentation product produced by the soil-dwelling actinomycete bacterium Streptomyces avermitilis.
How does Abamectin move inside plant leaves?
It possesses translaminar movement, penetrating through the leaf surface and creating a reservoir inside the leaf tissue to kill leaf miners and underside mites.
Which major pest does Abamectin control in commercial vineyards?
It provides exceptional control of two-spotted spider mites and thrips in grapes under CIBRC label approvals.
