OMRI-Listed Biofungicide

Protect your crops from Downy Mildew, Late Blight, Root Rots, Phytophthora and Pythium with ZONIX™ Biofungicide. ZONIX is an OMRI-listed biofungicide recommended as a key part of integrated pest management (IPM) programs. It’s approved for application on seeds, transplants, fruits, vegetables, roots, seedings, cuttings and foliage. ZONIX, based on rhamnolipid technology, is a unique product that supports sustainable agriculture. Rhamnolipids are versatile and function not only as biofungicides, but also as a specialty additive and biosurfactant.


Dispersants prevent particles from agglomerating or aggregating during the milling process, in the formulation concentrate, and after dilution into the spray tank. Stepan offers a variety of steric and electrosteric products for use as dispersants in agricultural formulations.

Products Highlights:

Stepan Agricultural Solutions offers a broad portfolio of polymeric dispersants and wetting agents that, when properly matched, can provide a synergistic enhancement of aqueous formulations. The Polymeric Solutions for Aqueous Agricultural Formulation Development brochure highlights our line of polymeric dispersants and a selection of paired wetting agents designed for suspension concentrates (SC) and suspoemulsions (SE). We also offer these products in an all-in-one Polymeric Dispersants Kit so you can easily mix and match to find the optimum pair for your formulation.

STEP-FLOW® 4000 is a water soluble “comb” polymer dispersant for use in capsule suspension (CS) and SCs. Compliment STEP-FLOW 4000 with any products from our butyl-based block copolymers line or with STEP-FLOW 4894-SC.

STEPFAC™ 8181 PT3K is a 100% active, potassium-neutralized phosphate ester for use in oil dispersions (OD).

Carrier oils include STEPOSOL® ME, STEPOSOL ROE-W, STEPAN® C-42 and STEPAN C-65.

The STEPSPERSE® DF-Series offers traditional liquid surfactants in a dry form for use in water dispersible granules (WG) and wettable powders (WP).

Complimentary products include STEPWET® DF-90 and STEPWET DF-95.


Stepan offers a portfolio of green solvents for use in solvent-based agricultural formulations. Each product offers different characteristics to meet your formulation needs, whether they be high-pesticide solubility, low volatile organic compound (VOC), low irritation or others. These solvents can also make robust emulsions when optimized with Stepan emulsifiers.

Product Highlights:

Amides: HALLCOMID® M-8-10 displays a broad range of properties, including excellent solubility in organic solvents, low vapor pressure and heat and hydrolysis stability.

Methyl Esters: STEPAN® C-42 is a naturally derived, biodegradable solvent and STEPOSOL® ME is a methyl ester derived from soybean oil.

Specialty Solvents: STEPAN 108 is a caprylic/capric triglyceride made using glycerin from vegetable oil sources and medium-chain fatty acids from coconut and/or palm kernel oil. 


Adjuvants are a broad range of products that, when added to a formulation or tank mix, offer efficacy enhancement or application improvement. These can be tank mixed separately or added into a formulation.

Product Highlights:

STEPAN® 3109-6 is a specially formulated blend of surfactants designed for use in glyphosate formulations. STEPAN 3705-44, another formulated blend, is designed for soluble liquids (SL) formulations.

Tank Mix Adjuvants

  • STEPGROW 80 and STEPGROW 90 are sustainable nonionic surfactant tank mix adjuvants. STEPGROW 80 is a general purpose spreader and adjuvant for use in herbicides, fungicides and insecticides. STEPGROW 90 is an APE-free spreader and activator adjuvant designed to enhance the performance of a range of crop protection products.
  • STEPGROW AMS is a convenient and novel liquid spray tank adjuvant that is designed primarily for use with herbicides that are susceptible to hard water antagonism. This economical, low-foaming adjuvant promotes aggressive weed control with a broad range of glyphosate-based herbicides.
  • STEPGROW® CT is a tank mix compatibility adjuvant designed to help eliminate the challenges of complex tank mixes and delivers superior performance in spray applications. 
  • STEPGROW DRT-S is a spray adjuvant designed to reduce the generation of fine spray droplets that are susceptible to off-target movement during application. STEPGROW DRTS improves deposition of the spray droplets onto target plants and improves spreading on the leaf surface.
  • STEPGROW® NPRO 101 is a nitrogen stabilizer designed to protect urea-based fertilizers from ammonia volutilization. STEPGROW NPRO 101 prevents the hydrolisis of urea by inhibiting the urease, thus promoting nitrogen availability for the target plant.


Stepan offers a wide range of surfactants that allow for micelle formation of an oil phase within a water phase and inversely. These include anionic surfactants, nonionic surfactants of varying HLBs and surfactant blends.

Product Highlights:

Stepan’s single component emulsifier portfolio includes alkoxylated hydrophobes, phosphate esters and their salts, as well as alkylbenzene sulfonates and their salts.

TOXIMUL® 8320 is a nonionic surfactant used to emulsify systems heavy in chlorinated solvents and pesticides, and has a lowered pour point to reduce any handling issues.

Stepan's Butyl-Based Block Copolymers portfolio are multi-functional polymeric surfactants that are excellent emulsifiers in oil-based formulations and can be used across a range of agrochemical formulations.

The TOXIMUL® 3470F Series of products are anionic/nonionic surfactant blends that can be used as effective emulsifier blends for pesticide concentrates. These products can be used individually or in combination with any other in the series:

A Novel Solution for Rheology Modification of Agricultural Formulations

Formulators face multiple challenges while successfully developing a commercial agrichemical formulation. One way formulators address these challenges is to manipulate viscosity to improve formulation stability. Stepan Agricultural Solutions is excited to introduce our novel, structured surfactant technology that provides elastic suspensive media to water-based suspension concentrate formulations and rheology modification of electrolyte solutions.
