Stemma pH Master
Water pH regulator for foliar treatments
Fertigation • Foliar
Stemma pH Master is a formulation with an acidifying action that regulates the pH of the water used for the foliar treatments.
Stemma pH Master allows to increase the availability of the nutritional elements by solubilizing them, to improve the miscibility with various products in solution and to increase the functionality of the agrochemicals.
Thanks to its formulation, Stemma pH Master has both high wetting and strong sticking effect.

The doses depend on water hardness and on the desired pH level. Added to water, VYRER PLUS produces a color change that, with the help of the color scale present on the label, allows to visually measure the final pH of the solution.
It is advisable to start with 50 ml/hl, increasing the dose until reaching the color corresponding to the desired pH (according to the color scale). The product can be poured directly into the atomizer or other containers used for the application.
For foliar applications as a fertilizer, we suggest using it at 150 – 200 ml/hl.
