In modern agriculture, the effectiveness of pesticides and foliar fertilizers is influenced not only by the active ingredients but also by the adjuvants used in the spray system. Organosilicon agricultural adjuvants, known for their low surface tension, excellent spreading, and strong penetration, play a key role in enhancing pesticide performance.
Based on formulation type, organosilicon adjuvants are mainly available in liquid form (IOTA-2000) and powder form (IOTA-2001). Understanding their characteristics and suitable applications helps farmers, technicians, and sales professionals select the most effective product for specific needs.
IOTA-2000 Liquid Type
High active content liquid, colorless to light yellow
Active ingredient ≥99%
Ultra-low surface tension (~21.5 mN/m)
Soluble in various organic solvents and dispersible in water
Rapid spreading, strong penetration, suitable for liquid pesticides and foliar fertilizers
IOTA-2001 Powder Type
Dry powder, white to light yellow
Active ingredient ~50%
Easy to incorporate into powder formulations, uniform dispersion
Improves spreading and penetration of powder pesticides
Suitable for wettable powders (WP), granules (GR), water-dispersible granules (WDG), soluble powders (SP), and powder foliar fertilizers
| Feature | IOTA-2000 (Liquid) | IOTA-2001 (Powder) |
|---|---|---|
| Spreading | Ultra-low surface tension, rapid leaf coverage | Improves powder droplet spreading, reduces particle loss |
| Penetration | Strong, promotes penetration through leaf cuticle | Good, enhances absorption of powder-based sprays |
| Efficacy Enhancement | Rapid onset, fast absorption of liquid active ingredients | Extends powder effect, resistant to rain wash-off |
| Application Method | Tank-mix or formulation addition | Mixable into powder formulations, dry and easy to store |
| Crop Safety | Low phytotoxicity, safe for crops | Safe for multiple powder formulations |
| Convenience | Liquid, easy to measure and apply in the field | Dry powder, easy to blend, suitable for industrial-scale formulation |
IOTA-2000 Liquid Type
Suitable for sprayable pesticides, foliar fertilizers, and plant growth regulators
Ideal for tank-mix applications, providing rapid spreading and penetration
Stable in liquid formulations, does not degrade active ingredients
IOTA-2001 Powder Type
Suitable for powder formulations such as WP, GR, WDG, SP
Easy to blend into powders, dry and non-caking
Small doses improve powder spreading, penetration, and rainfastness
Stable for long-term storage, ideal for industrial-scale formulation
Choose IOTA-2000 Liquid if the goal is fast-acting field spray, liquid formulations, and immediate results.
Choose IOTA-2001 Powder if the goal is powder formulations, industrial production, or long-term storage.
In integrated applications, the two can complement each other: liquid for tank-mix spraying, powder for formulation development.
Both liquid and powder organosilicon adjuvants have distinct advantages:
IOTA-2000 Liquid: High active content, rapid spreading, strong penetration—ideal for liquid sprays and formulations.
IOTA-2001 Powder: Dry, easy to disperse, rain-resistant—perfect for powder formulations and industrial applications.
By understanding their differences and applications, farmers and sales professionals can select the most suitable organosilicon adjuvant, achieving enhanced efficacy, reduced application rates, and crop safety.
