Has anyone ever used Ornamec 170 grass herbicide near agaves

Just heard about this from a popular flower (& more) farm in Texas.

I found this label info and it says it is safe on Agave americana and some other succulents. I assume that means it would be fine on all agaves, but I've never used any kind of sprays before so a little unsure uneasy.

What is the active ingredient? I just used Clethodim 2 days ago around my agaves, yuccas and dasylirions. I did not spray over the top however. Because these plants grow so slowly, any damage/death that occurs may not be apparent for several months and not be attributed to the herbicide.

I'm probably just being paranoid about ruining the agaves. Guess I could just keep it a few feet away from the agaves and hit the rest of the grass if I want to be overly cautious.

Update me on how well the clethodim works, please!

This might be the solution to my bermuda grass problem.

If it won't harm wildflowers, it probably won't harm agaves. You can spray Roundup on and around agaves without harming them, so long as an effort is made to keep it to a minimum.

I sprayed 4 days ago when temps were in the low 70s. Used the high rate of clethodim with pendemethlin and added .5oz non-ionic surfactant with a squirt of dye marker. The bermuda looks very sad today. The volunteer cool season grass was taller than recommended however it has lost a lot of green and and is flat.

I'm going to do another application after Thanksgiving but will be using methylated seed oil (MSO) in place of the surfactant. MSO slows the evaporation of the herbicide and is more effective in penetrating waxy cuticles.

A bit of trivia. Roundup was originally used as a growth regulator before it was a non-selective herbicide. Too many applicators were using the "more is better" technique and resulted in scorching turf.

I will give this a try... I just spent two hours yesterday pulling bunches and bunches of several feet long stringers of Bermuda grass out of my Firesticks bush and besides getting sick of it and hurting my back in the process, I got to a point where I either decide to take out the Firesticks or spray with something and hope for the best. It will probably still take many re-applications to get it, but this sounds very promising.

It always best to avoid over the top spraying if possible. With bermuda carefully spraying around the base of the Firestick should provide good control of the stringers since they are unrooted. Also with bermuda being a warm season grass, do not expect dramatic results. For herbicides to be effective the target plant must be in an active growing stage. Bermuda will remain green in cool temperatures but not be growing. The bermuda I sprayed was adjacent/up against landscape blocks

Thanks for the advice! I actually spent quite a bit of time yesterday trying to create access to the areas where I would like to spray around the base of the Firesticks. Like you suggest I do not foresee myself just getting the sprayer out and going to town - while easy I know better than to blindly trust such labels. However, the idea that it is not going to be very harmful to Agaves (and other plants) make me less nervous about giving areas around the base of the plants a good drenching which I had hesitated to do with roundup.

One thing I can say: it is growing right now... we had some rain, it is in the 70s-low 80s during the day and still not very cold at night... I removed some lush green new growth that had not been there several days earlier. I wish the actual plants I want to grow would be growing like that right now.

Got one of these today. Hopefully it will save my back. The handheld versions work great. I will stil need to use the handheld but hopefully just a little bit.
