ROSTOK pH-CONTROL (WATER pH CORRECTING FERTILIZER)
"ROSTOK" pH-Control - a highly concentrated buffer that regulates the pH level of the working solution (acidifying effect) and prevents the destruction (hydrolysis) of active substances of drugs (PPP, growth regulators, microfertilizers); thereby maintaining their high efficiency during spraying or foliar fertilization of crops.
The dosage of the drug depends on the initial pH of the water and the pH of the working solution to be achieved.
The recommended rate of application of "ROSTOK" pH-CONTROL is 40-100 ml / 100 l of water.

When adding "ROSTOK" pH-Control to water, the solution visibly changes color to blue, green or yellow depending on the pH level of the water. The color scale for water pH levels is shown in the table.

It is advisable to start with 40 mg / 100 liters of water, gradually increasing the dose to achieve a color that corresponds to the desired pH level of the working solution.
ALWAYS ADD ROSTOK pH-CONTROL AS THE FIRST COMPONENT OF THE MIXTURE IN THE WORKING SOLUTION.
Steps of preparation of the working solution:
To prepare the working solution in the sprayer tank, filled with water to 1/2 - 2/3 volume with the mixing mode on, add "ROSTOK" pH-Control (until the working solution is light yellow).
After 3-4 minutes, add other components of the tank mixture (in the following order: microfertilizers, plant protection products, growth stimulants, urea-ammonia mixture, urea and other drugs) and add water to the full volume of the tank.
The working solution should be clear, should not form: sediment, lumps, gel or liquid stratification.
After that, start sprinkling the crops with a working solution. It is recommended to use the ready working solution on the day of preparation.
Compatibility with other drugs:
ROSTOK pH Control is compatible with most herbicides, fungicides, insecticides, growth regulators and microfertilizers.
Always read the packaging labels of other drugs and the recommendations for the pH of the working solution for them before use.
WARNING!!! It is not recommended to use "ROSTOK" pH-Control in tank mixtures with fungicides containing copper (including Bordeaux mixture, copper oxide, copper hydroxide, copper chloride), drugs that require alkaline pH to maintain their effectiveness (sulfonylureas).

PHYSICO-CHEMICAL INDICATORS OF THE PRODUCT
pH: 2,0-2,1
density: 1,15-1,20 kg/l
Mechanism of action:
"ROSTOK" pH-Control due to the special formulation of organic acids with buffering properties acidifies the water used in the tank mixture (lowers the pH level). The effect happens due to the neutralization of excess hydroxide ions (OH-).
Thanks to ROSTOK adjuvants, pH-Control reduces the surface tension of the drop, which allows the solution to spread evenly over the leaf surface and cover its maximum area, as well as promotes better penetration of the solution through the cuticle of the leaf.
The use of "ROSTOK" pH-Control for water helps to avoid the destruction of the active substance (alkaline hydrolysis) of various drugs: plant protection products, growth regulators, microfertilizers and others, which increases the efficiency of their work.
ROSTOK pH Control softens water by binding Ca2+ and Mg2+ ions to neutral compounds.
The presence of antifoam helps to reduce the formation of foam in the preparation of the working solution.
Method of use and cost norms:
The dosage of the drug depends on the initial pH of the water and the pH of the working solution to be achieved.
The recommended rate of application of "ROSTOK" pH-Control is 40-100 ml / 100 l of water.
Application of "ROSTOK" pH-Control:
- Reduces the pH of water by completely neutralizing excess hydroxide ions (OH-).
- Shows high buffering properties (effectively keeps the pH level of water in a safe range when preparing a multicomponent tank mix).
- Softens hard water by binding the cations Ca2 + and Mg2 + contained in it.
- Prevents alkaline hydrolysis of active substances of pesticides, fertilizers and other drugs and maintains their effectiveness.
- Improves the compatibility of drugs in the tank mix.
- Increases the stability of the multicomponent tank mix.
- Improves solubility and increases the efficiency of assimilation of pesticides, fertilizers, growth regulators in the tank mix.
General recommendations:
Sprinkling plants is best done before 9 am or after 6 pm at an air temperature of 12-25°C in windless weather. It is not recommended to carry out processing during the day in the scorching sun. Evening or morning dew does not affect efficiency.
The temperature of the water for the preparation of the working solution should be as close as possible to ambient temperature.
When mixing "ROSTOK" pH-Control with pesticides, the appearance of slight turbidity is possible.
Precautions: Personal protective equipment should be used when handling the drug. In case of contact with the skin, wash the contaminated area with soap and water. In case of contact with eyes, rinse thoroughly with clean water for few minutes.
Tare: 1 l, 5 l, 10 l.
Storage: Keep out of reach of children at a temperature range of 0-35oC.
