Re "Horticultural Dye"......
I run a garden maintenance business and often use Glyphosate. I mix it up
myself using the concentrated. Works out much cheaper than buying the
commercially mixed stuff. I find that adding a dye is invaluable to
identifying where you have sprayed, and more importantly, whether I have
sparyed something I didn't want to spray.
What do I use as a dye????? Food colouring!! I buy blue food colouring
from Woolworths. I use the blue because it is a bit more unobtrusive than
the red. A bit less obvious in my client's gardens but still useful to
identify. The blue still shows up quite well, without using HUGE amounts
of it. It gives a blue shade to plants I've sprayed.
Hope that is of some help.
