How to act

It is preferable to use chemical control on regrowth after slashing. Foliar spraying, including use of splatter guns, is effective in controlling lantana. A broad range of herbicides are approved for use on lantana. A hot fire will also help to control large infestations by allowing access and controlling seed germination. Mechanical clearing can be used to clear the initial infestation if it is large enough but followup treatments must be conducted. Isolated plants can be removed by hand with ongoing monitoring for regrowth necessary. There are a number of biological control agents that reduce growth rates reducing spread however these do not kill the plant.

Refer to Weed Control Methods.
