Hammer herbicide approved for hard surface use

Hammer, a total herbicide from Everris, has received approval to be used on hard surfaces by The Chemicals Regulation Directorate (CRD).

Originally for use on natural surfaces not intending to bear vegetation, permeable surfaces, overlaying soil and areas around ornamental trees and shrubs, Hammer has now been upgraded to a wider use for surfaces such as roads, industrial sites and gravels.

Hammer is made of two active chemicals: glyphosate and pyraflufen-ethyl. The latter gives a quick knockdown, blocking production of essential acids thus inhibiting the enzymes that drive photosynthesis. Within 24 hours signs of destruction are visible, but the glyphosate is still able to move systemically through the plant, completing the kill and stopping further growth.

The herbicide is rain-fast within six hours and is approved for tractor-mounted boom, walkover and knapsack application. It is best applied post emergence during the active growing period of weeds between April and September. It controls a
broad spectrum of annual and perennial weeds, including the stubborn brush weeds, bramble and bracken.
