OPTYSIL® is an innovative silicon immunity biostimulant, containing active silicon form, which owes its effectiveness to unique formula duoSIL™
OPTYSIL® – BENEFITS
Increased plant tolerance to
drought and low temperatures
leaves, strengthened by silicon deposits in cell walls, demonstrate reduced transpiration and therefore plants are more tolerant to periodic water shortages and low temperatures
lower plant susceptibility to
pathogen penetration
strengthened cell walls are natural barrier limiting the penetration of pathogens and their spreading in plant tissues
lower plant susceptibility to mechanical damages
cell walls, strengthened by silicon, are less susceptible to damages caused by strong wind, hail and pests
better yield quality
flexible and strengthened by silicon epidermis is less susceptible to cracking caused by pests and sunburns. Fruits are more durable during harvest, transport and storage
better root system development
increased silicon content in plant tissues stimulates phosphorus uptake from soil, which results in better root system development
OPTYSIL® owes its effectiveness to duoSIL® formula
OPTYSIL® is an unique, liquid immunity biostimulant with high content (200 g SiO2/L) of active silicon form, easy plant available. Unique formula duoSil™ , used in OPTYSIL® ensures easy and full availability of silicon contained in product, high stability and possibility of mixing with the majority of agrochemicals.
high content
of plant available form of silicon
high stability
due to the unique formula
excellent solubility and miscibility
with agrochemicals due to neutral pH
Silicon is one of the major component of the Earth’s crust. In soil, the majority of silicon occurs in a form of silica, which is subjected to limited and slow weathering releasing low amounts of monosilicic acid – the only plant available form of silicon. Monosilic acid occurs in soil in low amounts and is very unstable. Plants can uptake it in very limited amount, therefore foliar application of silicon in a proper form is very important.
OPTYSIL® is registered for use in organic agriculture in accordance with Regulation (EU) No. 2018/848.
OPTYSIL® – APPLICATION

FREQUENTLY ASKED QUESTIONS – FAQ
OPTYSIL® contains silicon in a unique formula that penetrates the cell walls of plants and thus stiffens the plant cells. The strengthened cells become more resistant to damage caused by pathogens, as well as to water loss.
OPTYSIL® is characterized by a formulation that allows it to be mixed with most agrochemicals available on the market. Before mixing, it is best to perform a small-volume miscibility test.
