Blue Foaming Agent; 4oz
Add this mild, non-ionic surfactant to the herbicide to produce great foam and it's blue, so you can easily see what you have treated! The foaming agent (51% active ingredient) is a plant extract (sugar and a fatty alcohol), so it has superior biodegradability. The blue colorant is a food dye: FD&C Blue #1.
This bottle is enough for about 5 to 10 refills of the Small Foam Herbicide Dispenser.
Not for sale in CA, ID, WA. The Foaming Agent does not contain herbicide (i.e., weedkiller). That is sold separately.
