Dithane F-45 Rainshield Specialty Fungicide RainShield Technology


Rainshield Technology is a unique combination of surfactants and wetting agents built into the formulation that give Dithane exceptional rainfastness, re-distribution qualities and plant adhesion. Applications not only stick to plants, but re-distribute on plant surfaces when moisture – sprinklers, rain, dew – is present. Dithane is surface-mobile, but not systemic.
