Pesticide Formulation

WETTABLE POWDER (WP) bulky, dusty, inconvenient,
more hazardous to manufacture than liquids.
WETTABLE GRANULE (WG) low dust, low solvent, suitable for soluble packs and unit dosing, some dispersion problems. Less
easy to measure than liquids.
EMULSIFIABLE CONCENTRATE (EC) simple, robust, versatile, proven, flammable, high solvent content seen as a pollutant.
SUSPENSION CONCENTRATE (SC) simple, robust, generally water-based, not suited to many a.i.’s, some sedimentation problems.
EMULSION IN WATER(EW) water-based, low solvent, some colloidal instability problems, less toxic than EC’s.
MICROEMULSION expensive, chemical stability problems.
CAPSULE SUSPENSION (CS) water-based, low solvent, robust, cost-effective, less toxic than EC’s.
DRY MICROCAPSULE advantages of a CS, less bulky to store than CS or EC.
TABLET convenient, unit dosing, easy to package, good image, some dispersion problems.
GEL good image, suitable for soluble packs and unit dosing, intermediate properties of liquids and
solids.
