I have this question to the experts here, What do you do with the excess herbicide liquids which you need to throw away.
Recently applied prodiamine and few days later some weed control. I mostly make a educated guess how much I need but some time I am left with 1/4 gl or couple of hundred ml of liquid which I need to dispose.
I don't know what is a good place to dispose these liquids without hurting the environment.
Is it OK to thrown them in the drain?
