I see the mix rate per gallon for spraying acreage but I can’t find the spot spray mix rate? I sprayed with I believe 3/4 tsp per gallon this past Friday. Just for spot spraying and like spraying along my fence line where weeds grow a lot?

And fwiw,

You can control most weeds at the medium rate. There's a smaller subset of weeds that require the high rate Celsius or more than one application.

If you know what weeds you are dealing with you may not need to do the high rate and have less risk to injury your grass.

Yeah but what’s the appropriate level for your avg yard spray? I wasn’t sure what low/ med/ high was?

Also, I think I read you don’t need a surfactant in the summer or for spot spraying? I can’t remember?

As P said depends on the weeds you are trying to control whether you mix and spray at low, medium and high dose rate. Those weeds controlled by low, med, high dose applications are listed on the herbicide label. I sprayed some Doveweed on 7/31 - label calls for a high rate, so that what I mixed and sprayed.

I always use surfactant, regardless of season or spot or entire lawn spraying.

I was trying to get a simple solution. If I spray at the high an I going to hurt the grass? If I fill a gallon or two sprayer that will last the avg homeowner awhile, likely going to shoot a bunch of different weeds.

Understood. Celsius sprayed at the high rate is safe on Centipede, St. Augustine, Bermudagrass and Zoysia. I almost always mix and at the high rate. 3.2 g, regardless of the weeds I’m targeting - never had a issue with turf damage.

Good deal, which is roughly 3/4 tsp right? Call me lazy but I’m not going to measure it in grams. So basically if I get a tsp measuring device and slightly under fill it with a gallon of water I can spray st Aug, centipede, and zoysia moderately without too much worry? Virginia buttonweed for example when it sneaks up on you and you see a 1 ft by 1ft plant you can just wet it well with no major concerns with the surrounding grass? I don’t mind some yellowing. Just don’t want to nuke my grass on accident.

The high application rate is 1 teaspoon/gal; medium rate - 3/4 teaspoon/gal; and low rate - 1/2 teaspoon per gal as per the label posted by Puff in his post above. Add 2 teaspoons of surfactant per gal of spray solution. Spot spray as you described - will not harm St Aug, Centipede, Bermudagrass or Zoysia. The label recommends the high rate for VBW, Doveweed and some others. Be patient and give it time to work.
