Application notes
Consumption rate: 50-180 ml per 100 l of water.
The consumption rate depends on the pH and hardness of water used to prepare the working solution. Before use, in a separate container dose the preparation as appropriate for specific water using the color scale. The optimum pH of the working solution must be within the range of 4.5-5.5.
To determine consumption when applying the preparation together with fertilizers or agrochemicals that also acidify water, pour water into a separate container, add the fertilizer or agrochemical in the required amount, and determine the consumption rate.
This sequence is used for estimation only.

Prepare the working solution immediately before use, and use it on the same day.
Fill 1/2 of the sprayer with water, add the estimated amount of Lacmus, and stir thoroughly. Then, add the plant protection chemicals in accordance with the usage recommendations for each specific preparation.
