Was it a blanket spray or did you spot treat? I have noticed that I tend to overapply when spot treating, so I ordered a very low flow nozzle and usually mix lighter than suggested to offset my issues.

Spot treatment- I used the fan nozzle that came with the sprayer. Do you have any recommendations for a low flow nozzle?

+1, I like to use a yellow (0.2 gpm @ 40 psi) nozzle for spot spraying.

I actually went with a stainless .10 gpm nozzle.

Was it an adjustable cone nozzle? If so, those are notorious for over application of herbicides while spot spraying. Also, if you are spot spraying, all you want to do is "mist" the weed and not drown it. I know it's hard to do as you want to make sure you kill it but you will end up hurting the surrounding grass too! I know from experience :lol:

I'd have to look- but this is the only thing that I can wrap my head around that might have happened. Definitely wasn't drowning the weeds- I know better than that (I think :lol: )

I've also been researching the backpack sprayer videos listed on this website (can't find the link at the moment). Great info here and a lot of take-aways. Hopefully, round 2 goes a little smoother.

 

The Rutgers videos are great.

 

I realize this is an old thread, but I ran into the same issue of applying Q4+ in spots for nutsedge and having it stunt the entire sections. Although the day got hot (into the 90s), I applied it in the evening (I believe around or even after sunset) when temps were in the 80s. Either that was still too hot for the bermudagrass, or I overapplied it where I spot sprayed. There are other yellowish spots around the yard where I treated random weeds.
