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: 

• TOXIMUL 3473F
• TOXIMUL 3474F
• TOXIMUL 3476F
• TOXIMUL 3479F
