Environmental Protection Authority officials have received 26 submissions from individuals and organisations on an application to allow certain herbicides to be used to control aquatic pest plants.
The Agricultural Re-assessment Group wants permission to use the herbicidesto target aquatic plants such as alligator weed, manchurian wild rice as well as a variety of grasses and sedges.
The herbicides contain one of four active ingredients currently approved for use on land.
The group has identified a small number of potential risks to aquatic organisms if there's uncontrolled spraying over water.
The EPA intends hearing the submissions towards the end of October.
