I may have geeked out on this a bit but does this sound correct?

In controling bermuda, crab and goosegrass in zoysia ORNAMEC states to add 2.5oz of 6.75% to

a gallon of water. This will dilute the mixture down to 0.131%. This was calculated using

C1V1=C2V2 formula.

I have the same product but only in 24.5% concentrate.

It seems some people have been putting 5-10 drops per gallon of the higher concentrate.

However, again, using the C1V1=C2V2 formula, it appears that 0.684 oz of 24.5% would be

needed per gallon.

Does my math check out?

What ORNAMEC states is being sparyed on the lawn.

C1V1=C2V2

2.5oz x 6.75 = i% x 128 oz

i = 0.131%

So this is the percentage that is being spread on the lawn.

So using the same formula but now I have a 24.5 concentrate and determine the vol to add to 128oz.

C1V1=C2V2

24.5% x ioz = 0.131% x 128oz

i = 0.684oz

0.5oz = 1 TBL

You would put 1.36 TBL or about 1 TBL and 1 tsp of 24.5% into one gallon of water to yeild the same spray concentrate.

10 drops does not even come close to this.
