Most common formulation types in the Crop industry

Public, CAC 20179

SolidLiquid

SL (Soluble Liquid)

SC (Suspension Concentrate)

EC (Emulsifiable Concentrate)

SE (Suspo-Emulsion)

EW (Emulsion Oil in Water)

OD (Oil Dispersion)

ME (Micro Emulsion)

WG (Dispersible Granules)

SP (Soluble Powder)

WP (Wettable Powder)

ME (Micro Emulsion)



Benefits of water-based formulations

SL and SC are the major water-based formulations

Those are environment-friendly formulations

Usually low cost due solvent-free types

Diluted with water at any ratio, easily to handle

Generally no smelling

No flash-point problems, it’s safe to transport

Proper efficacy performance, low phytotoxic

Soluble Liquid



Soluble Liquid FormulationsSL

A SL is the most simple and cheap formulation type

• Only water as solvent (or a polar solvent)

• Comparatively cheap inert ingredients

• No sophisticated production equipment necessary

• Easy to handle

• Increased safety for operators

Public, CAC 201712

SL: when diluted in

water, it forms a

solution



Soluble Liquid FormulationsMain active ingredients

Examples of a.i. Which are typically formulated as SL are:

• Glyphosate

• Glufosinate

• Dicamba (water soluble salts)

• 2,4-D (water soluble salts)

• Paraquat

• Mineral nutrients / Foliar fertilizers

Public, CAC 201715

Novel sugar based non-ionic Surfactant: Glucose derivative + fatty acids

Liquid product: 50% active content

High salt tolerant, fertilizer compatible

Water miscible, stable at pH 3.5-8.5

In-can and tank-mix use possible

Soil wetting agent



Synergen® GAFeatures at a glance

Public, CAC 201716

Spray retention and wetting agent in the leaf surface

Re-dissolution agent in the leaf (increased availability of actives/ salts for penetration)

Bio-enhancer

No phytotoxic

Specially indicated for fertilizers and (acid) herbicides or mixtures

_

WHEN SYNERGEN® GA is present on the spray, retention is improved, assuring

more efficiency for the application
