PRO-PH is a powerful acidifier designed to correct the basic pH of the solutions for foliar tretments.

PRO-PH enhances the effectiveness of the agrochemicals and herbicides normally employed, avoiding their inactivation caused by the water alkalinity. It also contributes to neutralize the undesirable salts present in the water, avoiding interferences.



Manganese (Mn) soluble in water … 0.5% w/w

Zinc (Zn) soluble in water … 1.7% w/w

Dosage and application methods

PRO-PH is added to the phytosanitary solution, in the final stage of preparation.

PRO-PH can be mixed with most of the agrochemicals; however, it is advisable to perform compatibility tests with products based on sulfur and/or copper.

As a rule, use 50 ml of PRO-PH every 100 liters of solution.

If the water used or some dissolved product causes a pH increase at very alkaline values, a maximum dose of 100 ml/hl can be reached.

We recommend the farmer to investigate about the ideal pH for the use of plant protection products. In case of doubt, is recommended to consult a technician.
