Conventional herbicide application systems don’t work well if desirable plants are mixed with weeds
Crown vetch invading a planting bed

Problems with conventional systems:
• Spray systems: high pressure creates fine droplets which cause overspray and drift
• Wiping systems: use absorbent materials that drip excessively and collect dirt and plant matter

What is the alternative?

Green Shoots Precision Foam Herbicide Application Systems
Large Foam Herbicide Dispenser with Foliar Nozzle
Large Foam Herbicide Dispenser with Extension Nozzle
NOTE: Large Foam Herbicide Dispenser Available Starting March, 2014

Large Dispenser used for foliar application to highly
invasive Japanese knotweed

Foam herbicide clings to foliage of invasive knotweed
9Herbicide spreads on leaf
10
Herbicide slowly dries on leaf –
increasing absorption

Foam herbicide (triclopyr amine)
applied to cut stump of invasive
buckthorn
131 Minute – Foam recedes but clings
14
1 min. 18 sec: Foam herbicide gradually soaks into stump
15
1 min. 40 sec: Foam
herbicide almost
completely soaked inwith no
drippage!

What are the results?
19
Small amount of concentrated foam herbicide (glyphosate)
applied to bull thistle rosette in lawn. . .
12 days later, the thistle is dead with no harm to grass even
though glyphosate is a non-selective herbicide!
20
Small amount of concentrated foam herbicide (glyphosate)
applied to invasive Canada thistle . . .
10 days later – thistle is dead.
21
Small Amount of concentrated foam herbicide (glyphosate)
applied to invasive perennial sowthistle. . .
15 days later the sowthistle is dead.
22
Tangled mass of crown vetch in a planting bed
23
Small amount of concentrated foam herbicide (glyphosate)
applied to bentstem base of crown vetch. . .
35 days later, crown vetch is dead with no re-sprouts.
24
Small amount of concentrated foam herbicide (glyphosate) applied to small weed tree. . .
18 days later – successful treatment
25
Small Amount of Concentrated Foam Herbicide (glyphosate)
applied to stump of invasive buckthorn. . .
One year later, the buckthorn stump Is dead with no sprouting.

Advantages of the Green Shoots Precision System
• Less risk to desirable plants: less overspray or drippage
• Herbicide uptake increased: foam herbicide sticks to and dries slowly on weed tissue
• Visibility Improved: foam is easy to see• Reduced Herbicide Waste: only apply what is
needed for the job
