O1-YS™ – THE Organic Adjuvant

O1-YS™ when used in conjunction with your conventional integrated pest management program (IPM) will:

INCREASE – The coverage of your pesticide
IMPROVE – The performance of any IPM constituent
The efficacy of your conventional IPM program
The wetting and sticking ability to the plant
SPEEDS – The uptake and utilization of your IPM program

What is O1-YS™?

O1-YS™ is a unique synergistic blend of principal functioning agents featuring the combined properties of a superior agricultural spreader and sticker.  It enhances the activity and performance of pesticides and foliar nutrients.  With foliar applications, the superior wetting of O1-YS™ results in a more uniform distribution of material which increases the retention and absorption of sprays by reducing surface tension of the spray droplets.  When applied to the soil, O1-YS™ improves wetting of hydrophobic soils by increasing water penetration into the soil matrix.

O1-YS™ can be applied to all crops including, fruits and vegetables, field and row crops, turf, fruit trees, nut trees, ornamental trees, vines shrubs and flowers and containerized plants.  O1-YS™ is not designed for aquatic use.

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.

Row Crops & Vegetables

The use of O1-YS™ in row crop production when used as an adjuvant with your existing treatment protocols provides several advantages.  Harvest results showed a more than 40% increase in yield from the O1-YS™ treated rows over rows receiving conventional treatments.  It is known to chelate nutrients and minerals and to enhance the plants health and vigor.


O1-YS™ may be used as an additive in your surface coating protocol on fresh fruits and vegetables to decrease the transpiration loss.  Yucca products have GRAS status, making them FDA-approved for use in humans.


In viticulture, addition of O1-YS™ to IPM protocols leads to much greater yields and significantly healthier vines.
