Insects And Mites Found Attacking Cereal Crops In Western Australia, Clee Francis Howard Jenkins

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

ONE of the most important factors influencing Western Australian agriculture in the last 20 years has been the development of permanent pastures together with the associated practice of ley farming.

Although the increased use of pasture plants, and particularly subterranean clover, has increased the general fertility of many areas it has also accentuated various problems, including those relating to insect control.

Summer fallow was a strong deterrent to such pests as the red-legged earth mite, the lucerne flea, and webworm and these and several other creatures have shown a tendency to increase under new farming methods.

Weed Control In Cereals, G R W Meadly

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

WITH seeding almost completed, it is appropriate to review our knowledge of weed control methods in order to undertake any necessary planning.

Although cultural operations provide the first line of attack in the control of weeds in cereals, chemicals are playing a very important and increasing part.

The principles underlying cultural methods, including prevention from seeding and exhausting dormant seed reserves in the soil, are well known and it is intended to devote this article largely to the use of chemicals as herbicides, along with the various implications.

Diseases Recorded On Cereals, Grasses And Pasture Legumes In Western Australia, S C. Chambers

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

This list constitutes a revision of portion of the census published by Came (1925) and supplemented by the same author in 1927.

It also contains records of diseases identified in the period between these earlier publications and December 31, 1959.

The list is divided into two sections, the first dealing with pasture legumes and the second with cereals and grasses.

The sections are arranged alphabetically according to the botanical names of the host plants. In general, the viral, bacterial, fungal and nematodal diseases and physiological disorders are listed in that order.

Some Results With Nitrogen Fertiliser On Cereals At Esperance Plain Research Station, William John Toms

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

ON newly-cleared land at Esperance Plain Research Station the use of sulphate of ammonia on cereals has proved profitable over a number of seasons.

The response to sulphate of ammonia varies markedly with the season.
