Not to beat you up lakedoc. I catch myself making general statments here as well. but chemcial application advice needs a little more attention.
I have posted this before but I'll do it again. A few years ago I was spraying Reward on a very windy day. my sprayer is driven by a 5.5 Honda and puts out 9 GPM (max) the mist off the gun can be significant. I accidently caught a breath of that mist and it burned the hell out of the inside of my nose. I had nose bleeds for weeks. it took quite a bid of flushing (and all my drinking water) just to be able to drive home. I thank goodness I had enough sense to put my goggles on that day.
needless to say I look like the poster boy for chemical application saftey these days. be careful with these aquatic herbicides boys. wear your gloves, goggles or face shield, long sleeves, etc. you dont want it on you, I promise.
