Project Summary:

Imazethapyr (Spinnaker) is a new herbicide used to control a wide range of grasses and broad leafed weeds in pulse crops and lucerne pastures. However on acid soils and under dry conditions, residues of Spinnaker may carryover to affect the following cereal crop. This project is investigating the sorption mechanism operative on Imidazolinone herbicides in acids soils, and the potential to develop a microbial inoculum capable of enhancing the decomposition of these herbicides in soil.
