The standard broadleaf spray is a three chem combination. It is sometimes spiked with other things. But, the base triple action/three-way/strike3/Trimec/weed-b-gon is the same. It's exactly the same product that I use commercially. The exceptions being the concentration and volume. If you can get used to reading the fine print on the label of the active ingredients and giving the brand name a passing glance you will be better off.
The same three, 2,4-D, dicamba, and mecoprop, appear nearly universally in broadleaf sprays. I am seeing triclopyr in the retail side more these days. There is one called Speed zone that has an extra kicker called carfentrazone. It's not ok for StA. It can be used on bermudagrass and zoysia.
There are others though. They are more expensive. However, I can use them for a wider range of targets.
How Celsius Herbicide Works
Celsius postemergent herbicide contains three active ingredients. Dicamba penetrates the weed and translocates throughout its system, immediately stopping growth. Iodosulfuron-methyl-sodium is a selective chemical and most effective on young weeds. Thiencarbazone-methyl is the third ingredient and inhibits photosynthesis. Without this process, the weed cannot survive and dies within a few weeks. Once applied, Celsius stops weed growth in a few hours and total weed death in a week or so.

ENVIRONMENTAL HAZARDS
This product is toxic to non-target plants. Non-target plants may be adversely affected if the product is allowed to drift from
the areas of application. Avoid spray drift from treated area. Do not apply when conditions favor drift from treated areas. Do
not apply directly to water, to areas where surface water is present or to intertidal areas below the mean high water mark.
Do not contaminate water when cleaning equipment or disposing of equipment washwaters or rinsate. Do not drain or rinse
equipment near desirable vegetation. Refer to the Spray Drift Management section of this label for additional information.
This product may impact surface water quality due to runoff of rain water. This is especially true for poorly draining soils
and soils with shallow ground water. This product is classified as having “high potential for reaching surface water via
runoff,” according to the chemical’s “mean” soil partition coefficient (Kd) for several days after application. A level well-
maintained vegetative buffer strip between areas to which this product is applied and surface water features such as ponds,
streams, and springs will reduce the potential loading of this herbicide from runoff water and sediment. Runoff of this product
will be reduced by avoiding applications when rainfall is forecasted to occur within 48 hours.
Some of the chemicals in this product have properties and characteristics associated with chemicals detected in ground
water. These chemicals may leach into ground water if used in areas where soils are permeable...
