That's a good post, and I agree that you need to be careful with Clethodim or any of the grass herbicides. I have told people that I use 10 oz, but I have seen damage at that rate. And I think you are right that it's very dependant on the amount of rain you get. I have tried 8 oz and found that it didn't do a good job of controlling the grass in some fields. I think there is a very narrow window for how much Clethodim you can safely use. The window for Milestone is much wider and you can use more of it without damage.

I don't know about everyone else, but most of the herbicide damage I get is from poor application on my part. I now use a boomless sprayer and it is real easy to overlap the spray rows and give some spots a double dose. I have started cutting limbs and wrapping toilet paper on the ends for visibility, then putting them at measured distances on each end of the field so I have a guide to keep my spray rows consistent. That takes a lot of extra work, but it's worth it.

It doesn't hurt a thing to overlap when spraying deer plots with gly, but you need to be precise with chufa spray.
