Optimum Seed induces root growth and especially hair root growth therefore; the flow of water uptake is higher and increases the plant’s ability to take up more minerals and fertilizer components, resulting in higher vigour and germination uniformity. Optimum Seed is also used in some species as a replacement for priming.

Optimum Leaf gives a higher yield and has a positive effect on the colour of the plants exterior. Application of Optimum Leaf is a foliar treatment and has to be applied between 1 and 3 times per season. Optimum Leaf is only available as a concentrate and has to be diluted to a 5% concentration using ordinairy tapwater.

Optimum Bulb is our biostimulant especially made to help tuber/bulb crops e.g. potatoes, onion sets, tulips and lilies and to give them a head start. The plants will show a more uniform growth throughout the season and tubers and bulbs treated with Optimum Bulb are more uniform in size which increases the saleable yield.
