Bedstraw Eradication Program 2021/22: Annual Report To Grain Growers, Department Of Primary Industries And Regional Development, Western Australia

Agriculture reports

Three-horned bedstraw is a competitive weed that can cause considerable yield loss in crops, and its seeds contaminate fodder and grain. To stop the weed becoming established in Western Australia and impacting production, WA grain/seed/hay growers (via the Grains, Seeds and Hay Industry Funding Scheme) fund the Bedstraw Eradication Program.

Skeleton Weed In Western Australia: Management Guide, Department Of Primary Industries And Regional Development

Bulletins 4000 -

Skeleton weed is a declared plant which can reduce crop yields by competing for moisture and nutrients (mainly nitrogen).

This Management Guide has been designed to assist landholders and increase their capacity to manage and eradicate skeleton weed infestations on their properties and to prevent further spread within the State. Without the coordinated program aimed at controlling spread, skeleton weed would now be much more abundant and widely established throughout the cereal growing areas.

Skeleton Weed In Western Australia Control Program 2021/22, Department Of Primary Industries And Regional Development
