Control Of Wild Oats, J G. Paterson

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

WILD OATS are widespread throughout the world.

Their importance can be gauged from the fact that in the wheat growing areas of Canada and the U.S.A. some 60 million acres are infested.

Two chemicals are now available for the control of wild oats in wheat. This article compares their relative merits and gives recommendations for their use.

Poison Plants Of Western Australia : The Toxic Species Of The Genera Gastrolobium And Oxylobium. 1. Characteristics Of The Group, T E H Aplin

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

THE toxic species of the genera Gastrolobium and Oxylobium are a unique group of poison plants which have caused considerable economic loss to stock-raisers in Western Australia ever since the early days of settlement.

These plants are widely distributed over the agricultural areas of the south-west, and, with the opening up of large tracts of land for stock-raising, the danger is as high as it has even been.

THE extent to which seasonal conditions favour the various stages of plant development has a marked effect on cereal yields. Because varieties differ in their development they react in different ways to a particular seasonal pattern.

Legume Inoculants For 1967, W A. Shipton

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

PERIODIC changes are made in the strains of rhizobia released for the inoculation of various legume groups.

These changes are made when it is evident from experimental data that better strains of rhizobia are available, or that the old ones are no longer effective.

New strains of rhizobia may give improved nodulation of legume seedlings or increase dry matter yields.
