Hi,
As an example, let's imagine the recipe you want to use is
JS 1:500 + JWA 1:70 + JHS 1:70
and the size of your sprayer tank is 20L.
First, fill 3/4 of your tank with soft water.
For 20L tank, use 15L of water.
Then measure out JS and add it to the water in your tank.
If recipe calls for JS 1:500, and you want to make 20L of pesticide, you need to add 20000/500=40ml of JS.
Next, measure out JWA and add it to the tank that is already filled with mixture of JS and soft water.
The recipe in this example calls for JWA 1:70 so to make 20L of pesticide, you need to add 20000/70=285ml of JWA.
You don't have to be extremely precise, just add 300ml.
Then, measure out JHS and add it to the tank.
According to the recipe in this example you need to use the same amount of JHS (1:70) as JWA, so use 300ml.
Next, stir the mixture well.
Last, add more soft water to make 20L of pesticide.
In this example you will need to add 20000-15000-40-300-300=4,4L of water.
Stir again and use.
