Lupinosis, H W. Bennetts

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

LUPINOSIS is a disease which has caused severe mortalities in West Australian sheep flocks in recent years, and one which—because of the important role which lupins are playing in light land development—must inevitably continue to be a matter of serious concern.

Rice Stem Borers At The Kimberley Research Station, L E. Koch

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

STEM boring caterpillars have severely damaged rice crops at the Kimberley Research Station, near Wyndham, and studies have been made on the biology, abundance, and control of these insects.

Hormone Sprays For Apricots, J E L Cripps

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

VARIOUS hormone sprays have been applied to apricots with the object of increasing fruit size and hastening maturity, and of these 245TA, the tri-ethanol amine salt of 245 trichlorophenoxyacetic acid, has in general, proved the most successful.

The increase in fruit diameter obtained with this spray in Western Australia has varied between 5 and 15 per cent, and is due to an increase in the size of the cells within the fruit, not to the production of a greater number of cells.

Tobacco Seed-Bed Management, A E. Baker

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

A SUCCESSFUL tobacco crop depends initially on an ample supply of well-grown, disease-free seedlings available early in the planting season.

If planting is held up due to a poor supply of seedlings, the resulting crop will not be grown in the most favourable part of the season. Late-grown crops nearly always give low returns.

Scald Of Barley, S C. Chambers

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

SCALD is a common disease of barley during late winter-early spring and causes considerable damage to the foliage of many crops.

The fungus Rhynchosporium secalis is responsible for this disease which is very prevalent in all barley growing districts.

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

THIS mallee, formerly thought to be restricted to the Comet Vale district, must be very rare in that locality, since it is seldom found growing there, but on the other hand it has an extensive range, being found as far west as Perenjori. Kalannie and Kulja, thence eastwards to Comet Vale, and southward to Mount Holland which lies south of Southern Cross.

The Geraldton Strain Of Subterranean Clover, A J. Millington

THE cereal-growing areas of Western Australia form a narrow triangle extending about 700 miles from north to south, gradually increasing in width towards the south to about 150 miles.

Mosaic Disease Of Cucumbers : A New Resistant Variety, H L. Harvey

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

TESTS with the cucumber variety Ohio MR 200 which was introduced from the U.S.A. (1), have shown it to be almost unaffected by the cucumber mosaic virus. It is a good type and satisfactory yielder and promises to be the answer to the cucumber mosaic problem in Western Australia.

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.

Seed Storage In Relation To Germination, G R W Meadly

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

WE are often asked how long seed can be stored and remain suitable for sowing.

There is no single answer as the period depends on a number of factors, including the type of seed, its condition at the time of storing and the nature of the storage.

Bacterial Wilt Of Potatoes, Department Of Agriculture, Western Australia

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

EACH season, Bacterial Wilt causes heavy losses to individual growers in several of the potato districts throughout the South-West of the State.

The disease is incited by the bacterium Pseudomonas solanacearum E.F.Sm. and is most prevalent in the districts of Donnvbrook. Pemberton and Manjimup as well as in the area between Waroona and Dardanup.

It is a tuber-borne disease which is extremely difficult to eradicate, once it has been introduced on to a property.

The Fruit Industry In Other Lands. 1. The United Kingdom, Frank Melville

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

THE following report deals with the many aspects of fruit growing both technical and commercial covered during a tour of three overseas countries undertaken on behalf of the Department of Agriculture and the fruitgrowers of Western Australia.

In the course of the three and a half months spent on this work, 13 research establishments were visited and contacts were made with research personnel both within these organisations and elsewhere.

Visits to commercial fruit growing areas were made with extension officers and these included brief visits to packing houses.

Altogether I had discussions with 127 research and extension personnel and industry …
