What is OII-YS™?

OII-YS™ is a uniquely formulated all natural adjuvant proven to greatly increase the efficacy of nematicides, fungicides, fertilizers, herbicides, insecticides, and nutritional sprays. It can be applied to turf, fruits, vegetables, ornamentals and row crops.

OII-YS™ is a unique synergistic blend of principal functioning agents featuring the combined properties of a superior agricultural, soil wetting agent and nutrient enhancer to solubilize and transport nutrients benefiting the growth and development of all plants.

OII-YS™ is the only adjuvant of its kind and is an important addition to any grower’s arsenal. The one-two punch of OII-YS™ is delivered through the superior wetting and chelating properties of its principal functioning agents – yucca and chitosan.

Advantages of Yucca and Chitosan

Yucca is a staple ingredient in the food industry and is also used to prepare natural shampoos, cosmetics and liquid soaps. The same properties that make it safe and effective for these products, combined with its excellent wetting characteristics, make yucca a superior agricultural surfactant. Its biosustainabilty supports O2YS Corporation’s mission to provide green and environmentally friendly products to the industry.

Chitosan is a natural cationic polymer primarily derived from shellfish. Chitosan’s cationic feature brings excellent adjuvant sticker qualities to this formulation through its ability to chelate organic compounds and minerals. Your result is more healthy plants with increased vitality, vigor and yield.

  • Harvest results showed a more than 40% increase in yield from the OII-YS™ treated rows over rows receiving conventional treatments.
  • Chitosan has been investigated for many agricultural uses and is known to chelate nutrients and minerals, retaining them for use by the plant.


In use in vineyards, OII-YS™ leads to much greater yields and significantly healthier vines. OII-YS™ can also be used in post harvest applications along with fungicides and pesticides to enhance protection from spoilage and pest damage.
