Bluebush Seed : Cleaning, Drying And Storing, C V. Malcolm

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

BLUEBUSH (Kochia brevifolia) is a perennial plant which occurs naturally in Western Australia.

In the past it has attracted little attention, but in recent years it has created interest as a highly nutritious and salt tolerant plant well adapted to certain salt affected soils in the wheatbelt.

A previous article (Bulletin No. 2630) by Smith and Malcolm drew attention to its use. One of the problems in establishing bluebush is to obtain seed supplies.

Sclerotinia Rot Of Vegetables, S C. Chambers, M. Hardie

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

SCLEROTINIA ROT, caused by the fungus Sclerotinia sclerotiorum, is now one of the most serious vegetable diseases in metropolitan market gardens.

Over the past decade it has been steadily increasing in prevalence and if present trends continue, many growers may be forced to abandon certain crops.

Although most vegetables are susceptible, the greatest losses are occurring in the autumn planting of beans, cauliflowers and lettuce and in the production of cauliflower seed.

The Dehorning Of Cattle, J Shilkin

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

THE dehorning of cattle, both dairy and beef, has many advantages.

Breeders of stud cattle frequently claim that removal of the horns spoils the appearance of show animals and stress that the practice is cruel.

Whilst both these statements may, to some extent, be true, the advantages of the practice far outweigh any disadvantages.

Virus Pneumonia Of Pigs, J Craig, N. Macintyre

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

THIS disease is widespread in Western Australia and is undoubtedly a most serious source of economic loss to the pig industry.

The effects of virus pneumonia are such that in badly managed herds, widespread pneumonic outbreaks and deaths are common.

By contrast, in well managed herds, there is the more insidious problem of low or nil death rates, accompanied however by an appreciable fall in animal production.

The House Fly (Musca Domestica), Clee Francis Howard Jenkins

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

MANY insects are so commonly associated with man and his dwellings that they may almost be called domesticated.

Lambing Problems In Summer Rainfall Areas, H Suijdendorp

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

LOW lambing percentages have become a serious problem in the summer rainfall areas in the North-West of Western Australia.

Castor Beans In Trial Plantings : Bundidup Research Station, Wokalup, 1959-60, T Pavy

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

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.

Dwarf Fruit Trees, Frank Melville

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

IN this country where most fruits and particularly apples and pears are grown without irrigation, heavy crops and summer stress restrict tree size.

The aim of most growers therefore, has been to grow larger trees and little interest has been shown in trees with dwarfing tendencies.

However, in countries with ideal conditions for growth, trees tend to grow too big and become uneconomic in terms of labour costs.

Insect Pests And Their Control, Clee Francis Howard Jenkins

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

METHODS of insect control are sometimes classified under the following four headings— Quarantine, Cultural Methods, Biological Control and Chemical Treatments.

Each method has its own particular part to play in preventing the spread and multiplication of insect pests and it is essential for maximum results that everyone— whether he be a commercial grower or a backyard gardener—has a general understanding of the principles involved.

Chemical Poisoning In Animals. 1. Arsenic, H D. Seddon

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

ARSENIC is poisonous to all animals and to man in quite small amounts and exposure to poisoning is often a result of human carelessness.

It is present in many chemical dips used for control of insect parasites on stock, and in agricultural fruit sprays and weed killers whose relative cheapness makes their use economical.

However, their potential danger and the economic loss they may cause are a disadvantage.
