OPTYSIL® owes its effectiveness to duoSIL® formula
|
duoSIL®
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. |

|
|
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
OPTYSIL® is recommended for use in the cultivation of all agricultural, fruit and vegetable crops in the form of foliar sprays, fertigation and irrigation

Foliar treatments – general application times (◆ optimal, ◊ optional) |
- FOLIAR APPLICATIONS
OPTYSIL® is intended for foliar application in the form of an aqueous solution. OPTYSIL® can be used together with other agrochemicals after checking the compatibility.
Detailed recommendations for foliar application are presented in the table below. - FERTIGATION
Recommended solution: 500 mL of OPTYSIL® in 1000 L of ready-to-use nutrient solution. Use in a separate fertigation cycle or together with fertilizers after checking if suitable for mixing.
For field grown plants: use every 2 weeks.
For soilless farming: use several times during the plant growing season. - WATERING OF SEEDLING
Recommended solution: 0.1%, i.e. 100 mL OPTYSIL® in 100 L of water. Water the plants 2–4 times during the growing season.
