A Progress Report On Commercial Cotton Growing On The Ord River Project, William John Toms

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

The recommendations given in this article have been built up from the experience of the author in growing 200 acres of cotton in the Ord River area during the 1962-63 season for the Department of Agriculture, from findings made by Kimberley Research Station, and from discussions with the present farmers in the area.

When a new form of agriculture is introduced into a new area techniques and ideas change rapidly as farmers become acquainted with their new environment and the new crops. The recommendations will therefore require constant revision.

Chemical Sterilisers In The Dairy Industry, D N. Tulloch, N. Ingleton

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

There is concern in the cheese industry that residues from new chemical sterilisers used by dairy farmers could affect cheese making processes.

The sterilisers could also affect tests for antibiotic residues in milk. The responsibility of seeing that chemical sterilisers do not enter the milk belongs to the dairy farmers.

They should follow the manufacturers' recommendations and use the chemicals with care.

Rabbit Fumigation, C D. Gooding

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

Not all poisons act by absorption from the alimentary tract or through the skin, the fumigants are a big group of poisons used in pest control which act on the animal after being absorbed through the lungs.

FUMIGATION as it is now used in Western Australia is not always an economical way of treating whole farm properties. It should only be used on its own in areas where it is impossible to use other more permanent methods such as warren destruction.
