Emulsifiable Concentrate (EC) Formulations
Original SpeedZone herbicides were emulsifiable concentrate (EC) formulations. An EC is an oil-based formulation containing active ingredients that are dissolved in solvents and emulsifiers. It creates an oil-in-water emulsion when added to the spray tank.
- Offers spontaneous emulsification on dilution
- Delivers uniform application of active ingredient(s)
- Can have an odor
Emulsion-in-water (EW) Formulations
SpeedZone® EW and SpeedZone® Southern EW are emulsion-in-water (EW) formulations. An EW formulation technology creates a smaller particle size than an EC formulation. The smaller oil droplets result in more active ingredients impacting the leaf surface, which leads to improved efficacy.
- Engineered for use in low-volume and conventional sprayers
- Lower odor profile compared to EC
- Lower Volatile Organic Contents (VOC) compared to EC
Emulsion-in-water (EW) technology creates a smaller particle size than EC formulations, resulting in less drift (see charts), and more active ingredients impacting the leaf surface for improved efficacy compared to EC formulations. SpeedZone® EW and SpeedZone® Southern EW also offer a lower odor profile and lower Volatile Organic Content (VOC) compared to the EC formulation of original SpeedZone.
