Mechanism of Action

Colloidal silver (less than 30 nm, 0.1% concentration) keeps plant metabolism active and supports photosynthesis. Nitrogen and potassium also promote vegetative growth.

Application

Shake well before use. Can be applied via foliar spraying, fertigation, or cold fogging; suitable for outdoor and greenhouse use. A compatibility test is recommended before the first application. Combining it with AgroCyprum® further enhances its effectiveness, for example, on fruit vegetables grown under glass.
