This situation will require that the area be checked for seedlings on a regular basis. Foliar Herbicide Application Foliar herbicide application can be used on Brazilian pepper-tree seedlings. A herbicide containing triclopyr or glyphosate is applied directly to the tree's foliage. Results of a foliar application will be wilting of leaves. The herbicide will be translocated to other parts of the tree thus effectively controlling the Brazilian pepper-tree.
Foliar applications require considerably more herbicide to control Brazilian pepper-tree.
Also, damage to nearby plants resulting from wind drift of the herbicide should be avoided. Currently, there are no biological controls that have been released in the United States for Brazilian pepper-tree. Over two hundred insects have been identified that feed on Brazilian pepper-trees in the tree's native land. However, in order for them to be considered as possible biological control agents, scientists must prove that they are specific to Brazilian pepper-trees. Effective biological control agents must be able to reproduce after introduction into the United States.
