Tomato Bleach Spray Calculation Using 13% Bleach.
1 Answers
i got this usable recipe for tomato spray against blight
6% chlorox of 207ml mix with 3.78l water to spray on tomato and plants that is proven to be effective.
but i have 13% chlorox only.
how to calculation this ? can someone show me detail how to do it ? my brain is rusty.
i however have from the recipe above calculated that
1ml of 100% chlorox is to 320ml water.. that s the actual chlorox to water ratio that plant can take.
how do it plug in my above 100% chlorox recipe into calculation of 13% chlorox ?
appreciate it if anybody can help.

For more on marking an answer as the "Best Answer", please visit our FAQ.I'm no gardener, and I'm unsure why we have percentages rather than volume or mass, but in the hope I'm not missing some vital point:
You have more chlorex than you need. The easiest thing would be to simply not use all the clorex but use 6/13 ths of it.
If you must use it all then you need to increase the other parts of the mix by *13/6 (or *2.167).
As for the second bit, I'm not 100% clear what you have done but if you have used 100% and should have used 13% then you need to add to the other ingredients (presumably just water) by *100/13 (or *7.692).
Hope that is of use.
