I was at a gas station this morning and one large commercial lawn company shows up with 8 rigs they do the normal one or two fuels up and the other 3 go inside to get snacks ect. Well I noticed one guy pulling all the backpack sprayers off all the trucks and taking them to the diesel pump where he fills them all up and puts them back on the trucks! I’m fueling up my 75 gallon tank In the back of my truck next to the guy filling the sprayers I ask jokenly “extra fuel?” He says no it cheaper than roundup and this is what we use for weeds control. He mixes a little old motor oil in it as well he said. I was like holy Sh^t this guy is going to get nailed down the road. I will admit it does keep weeds dead for a while ( I use to be a mechanics assistant and around the oil and fuel dumps it splashed and killed the weeds) but this can’t be good for the soil it’s sprayed on especially for future plants/plantings.
