Mr Edmonds s asked the Minister in charge of the Commonwealth Scientific and Industrial Research Organization, upon notice -

1.   Has the attention of the organization been directed to the noxious plant known as Harrisia cactus, which has caused and is causing untold damage in the Collinsville area, Queensland?

2.   If so, what results have been achieved?

3.   If research has not been undertaken, and as the sugar cane farmers in the Lower Burdekin are fearful that flooding will cause the seed to be brought into this area and cause disaster to the valuable cane lands therein, will he arrange far inquiries to be conducted?


Mr Casey - The answers to the honorable member's questions are as follows: -

1.   The organization is aware that Harrisia cactus is a serious problem in Queensland, although & is understood that the area infested is not extensive at the present time. Some time ago it waa agreed at a meeting of the Queensland State Weeds Co-ordination Committee on which the Commonwealth Scientific and Industrial Research Organization is represented, that investigation! relating to the control of this weed should be the responsibility of the Queensland Department of Lands. Since then no approach has been made to the Commonwealth Scientific and Industrial Research Organization to conduct research on any aspect of the problem.

2.   It is known that a great deal of work has been carried out by the Queensland Department of Lands. It should be possible to obtain a report from that department on the results achieved.

3.   The Commonwealth Scientific and Industrial Research Organization executive would be pleased to arrange for officers of the organization to participate in a technical discussion of the problem; it feels, however, that the responsibility for callins such a meeting would rest with the Queensland authorities.
