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

10

Herbicide slowly dries on leaf –

increasing absorption

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
