View this PowerPoint presentation: Targeted Weed Killer: Precision Foam Herbicide Delivery System.  It explains the advantage of using foam herbicide:  less risk to desirable plants because of reduced drift or overspray ; an increase in herbicide uptake because the foam keeps the herbicide in contact with foliage longer; improved visibility because foam is easier to see than liquid; and reduced herbicide waste because the precision reduces waste.  We offer six different before-and-after examples such as the one shown in the following photos:

Application of Foam Herbicide to Bull Thistle Rosette

Dead Bull Thistle 8 Day after Foam Herbicide Application

Note this: in this application, the chemical used was glyphosate which is a non-selective herbicide.  If that herbicide had contacted the grass, it would have killed the grass too.  As shown in the photos, that didn’t happen.  This is a testament to just how precise you can be with the Green Shoots System. z
