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:
OPTYCAL increases calcium content of the plant, and thereby improves fruit quality and storage properties.
Additional benefits of activator OPTYCAL are:
| 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. Test results are presented in the table INTERMAG agrochemicals mixing table.
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
