Nzuron 25 WP does not kill the existing target population instantly. Due to its mode of action the larvicidal effect may be somewhat delayed and will only become fully apparent from the next moult following application.
Nzuron 25 WP mainly acts as a stomach poison, disturbing the moulting process of larvae at all stages. When last instar larvae ingest Nzuron 25 WP, disturbance in the pupal or adult cuticle may occur. This deviation from the normal moulting process ultimately leads to the death of the insect. Adult insects having finished moulting and pupation are not susceptible to Nzuron 25 WP.

The dosage of Nzuron 25 WP as formulation could be used as below for mosquito larvae control in the breeding areas.

Clean surface water           : 100-200 g/ ha
Polluted surface water      : 200-400 g/ ha
Closed systems                    : 1mg a.i. /lit
