Question 1

What is the mixing ratio of the concentrate to a gallon of water?

Accepted Answer

For Ground Application (Broadcast) the product label indicates a water volume of 1 to 10 pints of spray solution per 1,000 sq. ft. and lists the amount of concentrate to add depending on the type of area and height of the weeds. For spot treatment it says 2-3fl. oz. in 1 gallon of final volume of spray solution. Add a 1/2 gallon of water to your spray tank, for annual grasses up to 6" add 2fl. oz. of concentrate then top it up to a gallon with water. For annual grass up to 12" and perennial grass, add 3fl. oz. of concentrate to 1/2 gallon of water in your sprayer then top it off to a gallon with water. Keep agitating the solution during use.

Question 2

Is this safe on centipede grass?

Accepted Answer

This is safe for Centipede. I use it twice a year to kill off Torpedo grass in Louisiana. I use 2.5 oz to 1 gallon of water in a cheap pump sprayer. I learned to spray it after it rains but no additional rain in the forecast  when the grass/weeds are actively growing. I spray it in the evening when it is cool since it’s all 90 plus here in New Orleans.

This stuff works great!

Question 3

Is it absorbed by the grass leaves only or also by the roots?

Accepted Answer

It's a product to make a spray to be used on the leaves of grass like you would use the Ortho ready to use product Grass-B-Gon which costs about $6 for a 24 oz spray bottle. ($24 for 3 at Amazon) The Ortho product would be better to purchase from ace hardware if you only have need for only a single limited use. This concentrated product could  be used to mix with water and fill a gallon sprayer (4 oz gal) a couple of times or refill the 24 oz spray container about a dozen times.  The Ortho Grass-B-Gon product says not to cut the grass before using to allow it to get to the roots. It is absorbed into the roots from spraying on the leaves and it's effectiveness used on just the soil would be at a minimum greatly decreased if it worked at  all. It's  a great product for when grasses are mixed in with shrubs in your garden and you can just spray the grasses and a few weeks later they are yellow and dead. Many grasses have underground root systems and merely pulling the exposed grass does not eliminate the grasses from your garden This product can be used on some of an invasive grass taking over your garden and kill them from the root by spreading throughout the root system
