OII-YS is an all natural Nematicide and Chitin (Kiten) based adjuvant that must be applied in water with a pH of 6.0.
Therfore, we sell OII-YS in a 1 (one) acre Kit. The Kit has a pH meter to measure the pH of your water, an acidifer (citric acid) to lower the pH, and a neutral storage solution. Ground and surfase water ranges from a pH of 6.5-8.5 so we include the citrus acid to lower your water to a pH of 6.0. OMRI approved for the only organic chitosan and yucca based adjuvant in the market, O2-YS™.
