This sale is for a complete set of Round weed identification cards from the early 1990s produced by Monsanto.  The cards have a colour illustration of weeds, the rate of Roundup herbicide required for different applications.  

Hard to find and rare to come across a complete set.  100 cards in this set of which 86 are of specific weed species.

One owner (me).  Very useful cards for testing yourself on weed identification.  

In overall good to very good condition for their age.  Edges of cards have age spots and first and last cards have a few marks.

Disclaimer:  Please refer to manufacturer’s website and products for current information on the use of Roundup herbicide products.  Information on these Roundup cards may now be outdated.
