True, it's not straight gly. But, when you buy straight gly from the farm store it must be mixed with water. You end up with same thing, but buying straight gly is cheaper. That may be what you meant, I wasn't sure. I didn't want anyone going out and spraying straight gly on their fields.
It's also very helpful to add a non ionic surfactant to the srpay mixture. A lot of gly claims to have surfactant in it, but it's not a non ionic surfactant. It makes a difference. Some people add dish soap in place as a surfactant. It may help, but it's still not the same.
