Label says do not apply into any ornamental bed. But-- I think I remember Riggle saying something about it quite a while back, but---don't quote me on that.

Drive 75%
A review of the environmental fate data for quinclorac indicates that this chemical has
the ability to leach through certain soil types and contaminate groundwater; the
adsorption coefficients (Koc ) in sand and clay were reported to be 13 and 54,
respectively. These values suggest that quinclorac has a very high mobility through some
soils. In addition, the application rate for Drive∆ is not low (340.2 grams quinclorac per
acre, a maximum of twice a year). Accordingly, the label for the Drive∆ product states
under "Environmental Hazards" that "This chemical has properties and characteristics
associated with chemicals detected in groundwater. The use of this chemical where soils
are permeable, particularly where the water table is shallow, may result in groundwater
contamination."
There are no chemical-specific federal or State drinking water/groundwater standards
for quinclorac. Based on its chemical structure, this compound falls under the 50
microgram per liter ( g/L) New York State drinking water standard for "unspecified
organic contaminants" (10 NYCRR Part 5, Public Water Systems).

Just something to consider about this product used around ornamentals. I presume you aren't referring to shrubbery beds.!!!!

Thanks to that chemical profile, Drive, generic quinclorac and any 3 or 4 way products containing any quinclorac are illegal in Hawaii. The DOA does not care that there are no thresholds or standards for traces in drinking water.

Trying this on ornamental beds with shrubs is on the premise that not all broadleaf vegetation is susceptible to quinclorac. But isn't this stuff hard on conifers? I would think that there is a good reason why BASF did not research use of this material around ornamental shrubs. Like the fact that ornamental beds change and if sensitive species are planted next season, uh oh.

Green,
I was alarmed when Quinclorac(Facet) a Agricultural crop spray was suddenly shifted over to the lawn side of the spectrum. I was once told that this chemical......although not new at all.........could not be sprayed within a mile of a homestead or foodcrop area. The worker restriction reentry-interval is something like 48 hours. This should tell the world something!!!
The industry has pulled this product from the agri. side and slid it into the green industry under these new fancy pronounced names and with a little commercial finesse, it is a leading herbicide for lawns,etc. The truth about Quinclorac is it needs to be applied in standing water of at least 3-4 inches to be absolutely effective. This is what is applied around soybeans and rice after it is flood irrigated. So this leads me to surmise, it will leach and run and absorb. Maybe I am daft but I haven't seen any healthy tree lines, shrubs, ornamental trees withing the confines of crop fields as of yet. Makes you stop and think.

I cannot recall the exact shrubbery where I used Drive over the top to eliminate bindweed, (wild moning glory). As you know it is very difficult to remove same from yew bushes. And you are right--it is not on the label--except where it says Drive controls bindweed, several types of clover, wild violet, veronica and a few other weeds.
http://www.msuturfweeds.net/details/...d_bindweed_16/

And the label says to avoid desireable plants and "ESPECIALLY PLANTS BELONGING TO THE SOLANACEAE FAMILY SUCH AS TOMATOES, EGGPLANT, AND BELL PEPPERS."I would experiment, except my wife is watching me close whenever I go near her garden. My neighbor has some poison ivy where I could do a test. In a recent quick test Drive worked very well on crabgrass, clover, and fair on violets. Perhaps it should be combined with another herbicide and surfactant for violets.

I do not expect anything healthy near a crop field. Knowing that weed killers will damage more than weeds has a significant effect on what I will and will not do. Many people have a hard time understanding why I do not want lawn herbicides leaching or blowing into ornamental plants or backyard fruit trees. The new herbicides that I use are far more hazardous to surrounding vegetation. A little bit of 2,4-D, MSMA, or simazine does not worry me too much if a little drifts. In fact, my preferred product for non crop areas in production nurseries was MSMA because it would not do anything irreversible if it drifted. Anything "sulfuron" or "imaz" has me concerned because trace amounts drifting will cause permanent damage to plants. Glyphosate is the same. I would not imagine anything being healthy around a field planted to RoundUp Ready crops. If the crop is a Clearfield or ST, forget it.
