Lupinosis, H W. Bennetts

Journal of the Department of Agriculture, Western Australia, Series 4

LUPINOSIS is a disease which has caused severe mortalities in West Australian sheep flocks in recent years, and one which—because of the important role which lupins are playing in light land development—must inevitably continue to be a matter of serious concern.

FREEDOM from serious pests and diseases such as Black Spot and Codling Moth and relative immunity from storage rots has greatly simplified apple growing in Western Australia.

Visits to commercial fruit growing areas were made with extension officers and these included brief visits to packing houses.

Altogether I had discussions with 127 research and extension personnel and industry …
