BENEFITS

Broad spectrum of activity against household and public hygiene insects
Quick knock-down effect, particularly on flies
Efficiently controls insect population in treated area
Flushing-out effect
Easy photo-degradability (low residuality)
Excellently synergized by Piperonyl Butoxide
Excellently synergized by Piperonyl Butoxide

PROPERTIES

D-TETRAMETHRIN is a photolabile synthetic pyrethroid exhibiting mainly a knock-down effect, especially on flies, and is recommended in household and public health applications.

As for other synthetic pyrethroids, the efficacy of D-TETRAMETHRIN is strongly enhanced when combined with Piperonyl Butoxide which, thanks to its unique mode of action, excellently synergizes this class of insecticides.

APPLICATIONS

D-TETRAMETHRIN is an excellent knock-down pyrethroid suitable for applications against flying and crawling insects, particularly effective against houseflies and cockroaches.

When D-TETRAMETHRIN is synergized with Piperonyl Butoxide, its killing power is increased, while the recovery ability of insects is reduced or even eliminated, resulting in highly cost-effective formulations.

D-TETRAMETHRIN is typically used in water or oil based aerosols, but also in liquid concentrates (emulsifiable concentrates, macro-and micro-emulsions) and corresponding RTUs.

COMPATIBILITY, STABILITY,
STORAGE AND HANDLING

D-TETRAMETHRIN is compatible with most of the actives, solvents and co-formulants normally used in the manufacturing of insecticidal products, including Piperonyl Butoxide which also exhibits an excellent solvency power towards pyrethroids.

D-TETRAMETHRIN is sensitive to alkalis and strong acids, which rapidly hydrolyse the substance.

D-TETRAMETHRIN is also degraded by light and air exposure. When kept in the original sealed drums and properly stored, D-TETRAMETHRIN has a shelf life of at least 3 years from the manufacturing date.
For prescribed handling, storage conditions, disposal and, transport information, refer to the relevant Safety Data Sheet (SDS).
