## Can someone good at Algebra help with mix ratio of lawn weed killer?

Mixing up some Trimec for my lawn dandelions, I once figured out how to do it, wrote it down, and it has since gotten to the point I can't read it anymore.

What I have is this siphon sprayer for the hose which mixes at a 16:1 ratio.

Then I dilute the Trimec in a 5 gallon pail with water and spray it with the siphon sprayer which dilutes it more. It has worked well in the past, however I cannot for the life of me remember the percentage I diluted the Trimec and water to in the pail.

The end result out the end of the hose needs to be 1oz Trimec to 2 Gallons water.

Is the given information enough to form a formula?

Help!

Thanks!!

2 gallons = 256 oz

End ratio is 1:256

1/256 / 1/16 = 1/16

Ratio in the bucket should be 1:16

If you put 4 gallons of water in the bucket, add 32 oz Trimec

The last time I read the dilution instructions on a herbicide, it said to mix it with 100 gallons of water and spray it from an airplane.

I gave up at that point.

4. An option, if you don't feel like measuring: use the sprayer to create the 1:16 ratio in the bucket.

Pour straight Trimec into the sprayer, attach the hose and spray it into the bucket to make as much partial-mix as you want.

Empty any remaining Trimec out of the sprayer bottle, then fill it from the bucket.

Go kill weeds.
