If no pH meter is used (or the agent is used for the first time):
Take a transparent or white bucket of known capacity (e.g. 10 l). You should be able to clearly see changes in the solution’s color while in it.
Fill it with water you intend to use for spraying.
Measure the known amount of Lignum Plius (e.g. 10 m). Use a 10 ml syringe or measuring cup.
Slowly drip Lignum Plius into the water and mix intensively to spread the product evenly.
After noticing its color has turned orange, check the amount of agent left in the measuring syringe/measuring cup.
Calculate the amount of used agent accordingly. Write down the amount of agent used and recalculate the amount for 100 l of water.
Example of the calculations:
You poured 5.7 ml of Lignum Plius into 10 l of water and its color turned orange. This indicates that you should add 5.7 ml x 10 = 57 ml of Lignum Plius into 100 l of water
Calculation of application rates using a water pH meter:
Measure the pH of water intended for spraying and select a suitable application rate in the table below:
pH of water |
Amount of Lignum Plius, g (100 l of water in order pH to reach 5,5) |
9,0 |
100 |
8,5 |
90 |
8,0 |
80 |
7,5 |
70 |
7,0 |
60 |
6,5 |
50 |
6,0 |
40 |
Application rates of Lignum Plus may vary depending on the water and other agents used in the solution and how their chemical properties affected the solution’s pH.
Color indicator’s scale:
Attention: yellow color indicates that the water’s pH is more than 7;
Optimal: orange color indicates that the water’s pH is 5.5;
Attention: dark red color indicates that the water’s pH is less than 4.
