Mechanism of Action

Colloidal silver keeps cellular metabolism active, strengthens the immune system, and optimizes photosynthesis even under stressful conditions. The nitrogen and potassium it contains also support vegetative growth.

Application

Shake well before use. Apply via foliar spraying, fertigation, or cold fogging—flexible application options for both outdoor and greenhouse use. Before the first application, it is recommended to conduct a compatibility test with other fertilizers and plant protection products. The effect can be further enhanced when used in combination with AgroCyprum®.

Cultures

It has proven particularly effective for fruit vegetables grown under glass (including tomatoes and bell peppers) as well as for ornamental plants such as roses. It is also suitable for strawberries and other berries (using a higher dosage in this case, and specifically without boron), as well as for olives, grapes, and other fruits and vegetables.

Results

Independent trials showed that tomatoes grown under glass produced a significantly higher yield, more fruit per plant, and a noticeably higher vitamin C content. For strawberries, a clearly higher yield and more uniform fruit sizes were documented.
