Abstract: This disclosure provides an eco-friendly colloidal silver-based composition with the ability to prevent and control infections caused by pathogenic microorganisms in superficial organs of plants. The composition comprises water, colloidal silver, methyl vinyl ether copolymer, African palm vegetable oil, polyoxyethylene octylphenyl ether, triethanolamine, sodium hydroxide, and sodium benzoate. Due to its characteristics and the non-systemic application, the disclosed composition is non-toxic to host plants and other multicellular organisms.

Abstract: This disclosure provides methods of using an eco-friendly colloidal silver-based composition in preventing and reducing contamination caused by microorganisms in the plant tissue culture processes. The composition comprises colloidal silver, a copolymer, surfactant, a base, and water. The methods allow cultivating plants or explants in a plant tissue culture medium under non-aseptic conditions and thus obviate the need of the cumbersome and laborious procedures to sterilize the culture medium and the culture vessel in order to create aseptic conditions for plant or explant cultivation.
