Soil behaviour of pre-emergent herbicides in Australian farming systems

Soil behaviour of pre-emergent herbicides in Australian farming systems

When devising a weed control strategy, pre-emergent herbicides can be a valuable additional tactic to help drive weed numbers down.

To maximise the benefits and minimise the constraints, it is critical for advisers to have a thorough understanding of the properties of pre-emergent herbicides under consideration, to enable the best choice to be made. 

This manual is a reference for Australian grain advisers, covering the factors influencing the performance and break down of pre-emergent herbicides.
