Systemic herbicides are absorbed by the leaves (sometimes roots), and then translocates in the sap (upward and downward systemy). They destroy the whole plant, usually by destroying the chlorophyll, preventing root growth and distorting growth.They are generally very slow acting.

Approved in the UK:

• Glyphosate (ROUNDUP) – N.B. Dangerous to vines
