Additives for increased efficiency
 

Seaweed

The set of seaweed extracts effects a good and stable growth even under stress conditions (heat, drought, salinity, water stress and cold) due to the biostimulating effect of natural plant ingredients from four different algae species. As a result the plant remains stable and strong.

Folistick

External factors such as rain can cause wash off of the spay film. The new Folistick technology ensures a higher durability against external factors such as rain. Complesal® Folistick guarantees a lasting adhesive on the foliage to increase the uptake of nutrients and active ingredients of the added pesticides.
