Aqua K-Othrine is a space spray concentrate containing 2% deltamethrin, which will effectively flush mosquitoes out of their hiding places and kill through direct contact at extremely low dose (0.5-1.0g/ha of active ingredient). It is developed with Film Forming Aqueous Spray Technology (FFAST). This technology allows the use of water as diluents without the drawbacks of evaporation. Aqua K-Othrine provides longer-lasting spray cloud that is more effective in reducing adult mosquito populations. It is as effective as oil diluted space spray concentrates but without the oil and the cost.
