IOTA 2000 is a polyether-modified specialty silicone surfactant for agricultural applications, chemically classified as ethoxylated modified trisiloxane / polyether-modified heptamethyltrisiloxane. It features extremely low surface tension (21.5 mN/m), excellent spreading, penetration, and emulsifying/dispersing properties, significantly improving pesticide utilization efficiency. It is readily soluble in methanol, isopropanol, acetone, xylene, dichloromethane, and other organic solvents, and dispersible in water for convenient use.
IOTA 2000 is widely used as a spray modifier, foliar absorption adjuvant, and activator, suitable for herbicides, foliar nutrients, plant growth regulators, insecticides, and fungicides.
✅ Ultra-low surface tension – as low as 21.5 mN/m, significantly reducing the contact angle between spray droplets and leaf surfaces
✅ Excellent spreading & adhesion – rapid wetting and uniform coverage on plant surfaces, resistant to rain wash-off
✅ High-efficiency penetration & absorption – promotes active ingredient penetration through the cuticle, enhancing foliar uptake
✅ Good emulsifying & dispersing properties – compatible with various pesticide active ingredients without decomposition
✅ Reduced pesticide dosage – enhances efficacy while lowering pesticide application rates, reducing costs
✅ Green & safe – lower phytotoxicity compared to conventional fatty amine and ethoxylated alcohol surfactants; reduced environmental and human impact

Herbicides – improves wetting and absorption on weed foliage, enhancing weed control
Insecticides – promotes spreading and adhesion on insect bodies and leaf surfaces
Fungicides – improves coverage uniformity for better disease control
Foliar nutrients/fertilizers – enhances nutrient absorption and utilization efficiency
Plant growth regulators – facilitates penetration and translocation of active ingredients
IOTA 2000 significantly reduces the surface tension of spray solutions, allowing droplets to form uniform films on leaf surfaces, minimizing contact angles, and maximizing coverage area. Its excellent penetration facilitates active ingredient transport through the plant cuticle, improving absorption efficiency – achieving “reduced dosage with enhanced efficacy.”
✅ Ultra-low surface tension (21.5 mN/m) – exceptional spreading performance
✅ Enhances efficacy while reducing pesticide usage – cost-effective
✅ Does not decompose active ingredients – excellent compatibility
✅ Low phytotoxicity – environmentally friendly
✅ 100% active content – low addition rate, significant effect
✅ Versatile – suitable for multiple pesticide systems
