After hearing others say they have used it over irises with no problems, I used it this year. Very slow acting, but no problems for the irises that I could tell. no apparent negative impact on growth or fertility. 

The constant heavy rain is another story....
The three groups of broadleafs it supposedly works well on are composites (asters, wild lettuce, daisies, etc), legumes (clover, vetch, beans etc) and solanums (horse nettle, tomato, potato, pepper), and to a lesser extent, dock and sorrel (I guess that also means spinach & chard). So lots of warnings about persistence and potential effects on some broadleaf veggies for 2 yrs.
It definitely knocked back the vetch, I thought it hadn't done anything to the composites, but now that they are tall and trying to bloom, they are starting to look really bad, & I didn't have the heart to spray the daisies. yet. Some of the clover I sprayed is looking a little ill, but not dead yet, and the sorrel looks totally unaffected.
Weather was really cool and wet when I sprayed, so will see if some spot treatment of sorrel, dock and clover in sunny weather will work better, or if maybe they need fall treatment?
I feel a bit guilty using this stuff, but I've reached the point where I either spray some of the weeds, or give up trying to grow so many seedlings.
The weather casters are talking about this year's rainfall in relation to the annual record of 90+ inches here! When I was growing up, the 30 yr annual average was ~55 inches. Lately, thanks to a 5 yr drought, the average has been closer to 40 - I think the lowest was 32? Average really doesn't tell much!
