How Do IWOs Work?
Stretta
Irrigation Water Optimizer
Stretta is the first patented plant-derived irrigation water optimizer with fertilizer compatibility. Stretta improves the availability and performance of irrigation water, nutrients, and other soil-applied products throughout the plant root zone, optimizing the growing environment.
Features & Benefits
- Compatible with most fertilizer products including ammonium or potassium thiosulfate, ammonium nitrate, urea solutions, UAN, and phosphate-based fertilizers
- Enhances soil-applied input performance by maintaining ideal moisture levels in the plant root zone
- Holds water in the root zone, reducing stress and optimizing the moisture environment for plant growth
- Improves crop quality and increases yield
- Maximizes growers’ return on investment
Domino
Irrigation Water Optimizer
Domino is an advanced formulation of four irrigation surfactants, two that reduce the surface tension of irrigation water, one that holds plant-available water for the plant to use during periods of drought, and one that resists microbial degradation. This advanced formulation improves the movement of water into and throughout the soil and holds water for the plant to use during periods of drought.
Performance Results for Almonds
- 2.3% increase in tree height
- 2.8% increase in trunk diameter
- 4% increase in canopy width
Tolero

Irrigation Water Optimizer
Tolero is a unique formulation of a surfactant that reduces the surface tension of irrigation water and a surfactant that holds plant-available water. This combination of surfactants allows Tolero to improve the movement of water into and throughout the soil while holding water for the plant to use during periods of drought.
Performance Results for Table Grapes
- 9% increase in sugar content
- 5.5% increase in firmness
- 2.9% increase in berry weight
