OPTYSIL ULTRA is designed for foliar use and fertigation. It is compatible with the majority of commonly used agrochemicals. Before preparing a combined solution with agrochemicals it is recommended to perform a miscibility test.

FOLIAR FERTILISING:

Use in critical growth and development stages, every 10–14 days. In order to mitigate the effects of drought, spray the plants at least once before first symptoms of water deficiency appear. Continue the treatments every 5–7 days, 2–3 times. To enhance the uptake of phosphorus from soil, apply OPTYSIL ULTRA 2–3 times every 5–7 days.

FERTIGATION:

Use as a nutrient solution. Recommended concentration of OPTYSIL ULTRA in ready for fertilising nutrient solution: 35-55 mg SiO2/l (i.e.: 0.08 – 0.13 kg of OPTYSIL ULTRA / 1000 l of solution).
For soil-grown plants use every 3rd–5th fertigation cycle.
For soilless cultures use for watering mats several times during growth.
Apply separately.

WATERING:

Water the plants 3-6 times during vegetative season: with a 0.05% solution of the OPTYSIL ULTRA (i.e. 50 mg of the fertilizer per 100 l of water).
