Herbicide Pathways – An Overview

For a herbicide to effectively kill weeds it needs to get inside the plant, it needs to get to the tissue where the herbicide can work, and it needs to inhibit the active site.

Dr Chris Preston from the University of Adelaide explains how herbicides work at the Eyre Peninsula Agricultural Research Foundation (EPARF) members day held at the Minnipa Agricultural Centre.

The movement of herbicides in plants and soils depends on soil type, plant conditions and herbicide chemistry. Water solubility and soil properties are important for the activity of soil-applied herbicides whilst herbicide chemistry is important for leaf-applied herbicides.
