Description
Rootstar Intermag – foliar biostimulant
Rootstar is a foliar preparation exhibiting biostimulant activity – it activates auxin production in plants. It intensifies cell division and induces the formation of adventitious and lateral roots, as well as root hairs. It is intended for use after plant emergence to improve rooting, as well as during other growing periods to accelerate root regeneration after stress conditions (including frost damage, pest damage).
Rootstar Intermag, as a rooting activator, is part of the Stress Control System (SCS) strategy to support the natural resistance of plants.
Rootstar – main benefits of using the biostimulant:
- dynamic development of root mass,
- improvement of plant condition in early growth stages,
- increased plant tolerance to stress related to low soil temperature and water deficiency.
Composition of Rootstar Intermag:
- Total nitrogen (N) - 17 g/l (1.5% w/w),
- Ammonium nitrogen (NH4) - 17 g/l (1.5% w/w),
- Water-soluble zinc (Zn) – 67 g/l (6.0% w/w).
Rootstar Intermag contains a special form of zinc (ammonium zinc acetate) and substances supporting nutrient uptake and stimulating root system development (antioxidants and vitamins, e.g. B1 – the main ingredient of rooting agents).
How to use the Rootstar Intermag biostimulant?
Apply an aqueous solution of Rootstar Intermag foliarly as a fine- or medium-droplet spray. Rootstar can be used together with other products after conducting a compatibility test confirming the possibility of mixing.
Dosage can be adjusted considering the individual needs of plants and growing conditions.
