Cotton Fireweed : A Native Weed Menace, G R W Meadly
Journal of the Department of Agriculture, Western Australia, Series 4
INTRODUCED plants have provided most of our weed problems. Cape tulip, double gee and soursob come from South Africa, Saffron thistle, Paterson's curse, wild turnip and wild radish from Europe, mesquite from the southern United States and Bathurst burr from South America.
The relatively few native plants which have become troublesome weeds include Afghan thistle and Sarsaparilla.

Weed Control In Cereals : Aerial Spraying Trials, G R W Meadly
Journal of the Department of Agriculture, Western Australia, Series 4
SPRAYING cereal crops for weed control is now standard farming practice in Western Australia. Almost 500,000 acres of cereal crops, mainly wheat, are sprayed each year, and approximately three-quarters of this area is treated by aircraft.
Recent trials have shown that aerial application of 'extra low" volumes of hormone-like herbicides, with oil or water solvents, does not damage cereals if spraying is done at the right stage of growth.

THE main producing countries of the world are Brazil, India, U.S.S.R. and U.S.A. This means Australia has to import her supplies of castor oil, which has led to great interest in the possibility of growing castors in Australia.
Since the turn of the century, this interest has been increasing, and has accelerated in recent years, but it has never passed the experimental stage.

FARMERS west of the Great Southern Railway, raising sheep and beef cattle, frequently associate soil deficiencies with difficulties in holding sub. clover in their pastures.
Field observations and some trials in those districts indicate that in many paddocks the problem arises through undergrazing rather than a deficiency in the soil.
