Our most popular general weed control product that is selective, meaning it will not harm your turf grass but it will kill your weeds, is End Run. End Run is labeled for just about any weed you could have and will not harm your grass. Best of all, it comes with a surfactant already mixed in the product so you do not have to purchase and mix a surfactant separately like you do with most of the other herbicides that we sell. Here is a link to the End Run: http://www.domyownpestcontrol.com/endrun-herbicide-with-trimec-p-1501.html
As far as diquat, you can use that to kill weeds, but it will also kill everything else it touches including your turf grass. You can over-seed after using diquat, but just remember it kills everything it touches. You should use the End Run if you don't want to kill your grass and only kill your weeds.
EndRun Herbicide cannot be used on St. Augustine turf of any kind, primarily due to the volatility of the 2,4-D. (EndRun did have a previous label that allowed for use on St. Augustine turf, however that labeling has changed.) You should also note that most herbicides including EndRun specifically label their products 'not for use on drought stressed grass'.
No, Endrun Herbicide is not labeled to be used to control crabgrass. An alternative that we would recommend is Drive XLR8: it works for crabgrass as well as several other kinds of grassy and broadleaf weeds. Please read the label carefully to see if this product is compatible with the type of grass where you would like to apply it.

EndRun is labeled for just about any weed you could have including clover, dandelions, and chickweed and will not harm your grass. Best of all, it comes with a surfactant already mixed in the product so you do not have to purchase and mix a surfactant separately like you do with most of the other herbicides that we sell.
On page 4 of the EndRun Herbicide product label, it says that adding spray additives such as adjuvants or tank mixtures may alter the selectivity of the herbicide and may damage the leaf tissue of turfgrass. On the other hand, Drive XLR8 should always be applied with an appropriate surfactant, preferably one with methylated seed oil, such as the Dyneamic Surfactant. While sometimes 2 different herbicides can be mixed together, it would probably be best to apply these two herbicides separately.
Yes, EndRun Herbicide with Trimec is labeled to eliminate aster heath. The amount of product you use will depend on the type of turf you are treating. The amounts are based on warm and cool season turf. It is recommended that you spot treat the areas where the problematic plant is. This product is safe to use around ornamentals if you are using it as directed per the label.
