Silver ion solutions for use in agricultural spray formulations prepared for use in agricultural environs as an effective anti-bacterial spray, without environmentally hazardous or undesirable phytotoxicity. An iodine solution, a lime juice or a cranberry juice adjunct may be added to the silver ion solution in deionized water, to increase efficacy, especially in the ultra-low concentration range of the solution from parts per billion to parts per trillion of silver ion. The organically certifiable silver ion agricultural solution is applied externally to an agricultural commodity in the orchard or field, such as apples, cherries, pears, or any other fruit or vegetable.
