New Leaf Rust Helps To Control Blackberry, Jonathon Dodd, Sandy Lloyd

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

The release of spores of the blackbeny leaf rust in spring 1991 marked the second attempt in Western Australia at controlling weedy blackberries with a biological agent. The strain of rust now being used is expected to be more effective than the one released in the 1980s.

This article describes the techniques used for rearing and releasing the fungus and illustrates the effects of the rust on blackbeny.

Using Goats To Control Weeds, John Peirce

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

Feral goats are common in the woodland and tall shrubland areas of arid Australia. They survive and reproduce despite regular shooting, capture and droughts. These goats are considered vermin in Western Australia because of their competition with sheep for forage and their reputation as destroyers of vegetation. Research elsewhere, however, has indicated that it is only the uncontrolled grazing by large numbers of goats that causes degradation, in the same way that uncontrolled grazing by sheep can cause erosion. To some people, however, feral goats are a valuable source of income. They have the potential for meat sales, and they …

Beating The Blackberry, J H. Moore, E. B. Hoskins

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

The blackberry is an aggressive, strongly-growing plant that has spread throughout parts of the south-west of Western Australia.

Although most blackberry infestations on agricultural land have been dramatically reduced since compulsory control measures were introduced 30 years ago, about 3,600 hectares are still infested today.

Recent research has shown that three new herbicides are highly effective against blackberry, and much safer to use than the older ones.

Effective biological control of blackberry may also be possible.
