INSECTICIDE DEFENDA BOMBARDIER

Mechanism of action

Owing to its contact and stomach properties, imidacloprid damages the nervous system of adult insects and their larvae, irritating their receptors and causing convulsions and rapid death. Imidacloprid penetrates all parts of the plant through the leaves, stems and roots and is translocated acropetally within them. Imidacloprid acts as an antagonist of postsynaptic nicotinic receptors, subsequently destroying the central nervous system of insects, as a result of which the pests die. At relatively low application rates, it keeps insect numbers in check for a long period (in most cases, one treatment per season is sufficient).
