OPTYCAL is an innovative, water-soluble calcium activator for foliar application, improving the size, quality and storage properties of the crop. It ensures optimal supply of calcium at low doses.

 

OPTYCAL was developed using INT Technology which makes this activator particularly effective.

Watch the video about INT Technology.

 

OPTYCAL supplies the plant with calcium in two ways:

  • It stimulates the uptake of calcium from the soil and its transport to the youngest parts of the plant (auxin-calcium pump effect)
  • It directly provides easily assimilable organic calcium in foliar treatment.

 

OPTYCAL increases calcium content of the plant, and thereby improves fruit quality and storage properties.

Additional benefits of activator OPTYCAL are:

  • nitrate-free - can be used when plants are sensitive to excess nitrogen in the form of nitrates
  • unique composition and stable formulation enable combination with other agrochemicals
  • chloride-free

 

Nutrients Content [g/l] Content [% by mass]
Calcium oxide (CaO) 350 35.0
Formate 560 56.0
Boron (B) 1 0.100
Copper (Cu) chelated by EDTA  0.5 0.050
Iron (Fe) chelated by EDTA 1.5 0.150
Manganese (Mn) chelated by EDTA       0.7 0.070
Molybdenum (Mo)        0.02 0.002
Zinc (Zn) chelated EDTA               2 0.200
OPTYCAL features INT Technology, which significantly improves the speed and effectiveness of uptake, distribution and absorption of nutrients and stimulating substances by plants. These effects are obtained due to properly developed organic components.

 

OPTYCAL as a calcium activator is one of the elements of the strategy to support the natural resistance of plants STRESS CONTROL SYSTEM (SCS).

FOLIAR SPRAYS

OPTYCAL is intended for foliar application in the form of an aqueous solution. OPTYCAL can be used together with other agrochemicals after conducting a miscibility test. 
Detailed recommendations for foliar application are presented in the table below. You can also use the search engine and quickly find the dose rate and time of foliar application for your crop. Select your crop
