Monterey Spurge Power is not labeled to be used on groundovers so we cannot recommend it. If you have mondo grass, then you can use Image Kills Nutsedge for listed broadleaf and grassy weeds. That is about the only option we have for broadleaf weeds in groundcovers.
The Monterey Spurge Power only states that the following PPE (Personal Protective Equipment) is required when applying it to the lawn:
Should you choose to wear a mask for extra protection against drift or blow back of the chemical in wind, you are certainly welcome to do so and a basic KN95 or painters mask is more than sufficient.

Monterey Spurge Power should not be used on desirable groundcover or other ornamentals since it will likely cause damage to these plants. If you have grassy weeds in the myoporum, then you could use Fertilome Over The Top II Grass Killer to control the grassy weeds. If it is a large area, then you could also use a pre-emergent around the established ground cover, such as Snapshot.

We recommend you consult State Experimental Station or Extension Service weed specialist for specific recommendations for local weed problems and for information on possible lower dosages.

Monterey Spurge Power is not labeled for sandbur nor will it prevent new weeds from germination from seed.
For Warm Season lawns, a post emergent such as Image Kills Nutsedge or Celsius WG can be used when the weeds are actively growing.
For Cool Season lawns, we would recommend Acclaim Extra Herbicide along with a Non Ionic Surfactant for sandbur when it is actively growing.
We recommend using a pre-emergent for field sandbur in the fall, such as Pendulum 2G or Dimension 2EW:Granule.
Unfortunately, there are few options for post emergent control of Toothed Spurge and even using a non selective such as glyphosate at the highest rates have shown to be ineffective. The only product we can recommend would be Dismiss South Herbicide as it lists annual spurge (toothed spurge) as well as the other two common varieties, prostrate and spotted spurge. Repeat applications may be required and full control is not guaranteed.
One of the most common ways to deal with this weed in your gardens is to mulch the infested area, which prevents light from reaching their seedlings and seeds, depriving them of food before they can make it for themselves. Applying mulch that is 3 to 4 inches deep is typically affective.
