Dieback due to herbicide Metsulfuron-methyl
In April 2011 vegetation and trees within one kilometre of an area near Magowar Road, Girraween, suffered symptoms of dieback. An initial investigation by the Environment Protection Authority (EPA) found that the dieback was due to a herbicide, called Metsulfuron-methyl. This type of herbicide is manufactured by Du Pont (Australia) Ltd at 179 Magowar Road, Girraween. The EPA and the Ministry of Health assessed the impact and advised affected residents that the herbicide identified was of very low toxicity to humans. After an extensive investigation, the EPA commenced a prosecution of Du Pont in the Land and Environment Court over the Girraween incident
