1974 The Ecology And Control Of Doublegee (Emex Australis) And Emex Spinosa, D J. Gilbey

Experimental Summaries - Plant Research

The objectives of the field experimental programme for 1974 were to - 1) Evaluate a technique to measure pasture loss as a result of doublegee infestation at Merredin, Wongan.Hills and Chapman. 2) Evaluate the effect of cultural and herbicide treatment combinations on the magnitude and distribution of viable doublegee seeds in the soil at Avondale, Merredin, Wongan Hills and Chapman. 3) Measure the magnitude and distribution of viable doublegee seeds in the soil from paddocks representing each year of a two crop, plus three year pastureley rotation at Avondale, Merredin, Wongan Hills and Chapman. 4) Screen herbicides for selective control …

Faster Weed Germination With Early Cultivation, Geoffrey A. Pearce

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

The key to cultural control of weeds in cereal crops is an understanding of the factors which govern germination of the weed seeds.

Covering the seed with soil keeps out light, provides a stable moisture supply and makes germination faster than if the seed is left on the soil surface.

Shallow cultivation at the start of the growing season provides the soil cover needed for fast, even germination of weed seeds.

Spray-Graze : The Answer To Weeds In Pastures, Geoffrey A. Pearce

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

W.A. Department of Agriculture research leads to a new technique for weed control in pastures.

The trials which led to the development of the spray-graze technique of weed control started in Western Australia in 1966.

Since 1969, spray-graze has been tried in other States of Australia and is now recognised as the most practical method of controlling many pasture weeds.

Smooth-Stemmed Turnip, B J. Quinlivan, A. C. Devitt

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

Cruciferous weeds are common throughout the agricultural areas of Western Australia. They include wild turnip, wild mustard, wild radish, charlock and raphistrum weed or short fruited turnip.

Another one—tentatively named smooth-stemmed turnip—has recently been sighted. Its exact weed potential will not be known for some years, but it is likely to spread through the south coastal districts where the climate and sandy surfaced soils favour its growth.

Annual Pasture And Weed Plant Ecology, B J. Quinlivan

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

The purpose of this article is to outline a few basic principles of pasture and weed ecology with particular reference to seed dormancy mechanisms.

These principles apply to many pasture plants and weeds, although their relative importance varies with the particular plants under study.

The Control Of Weeds In Lawns, Geoffrey A. Pearce

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

MOST lawns have weeds growing in them at some time during the year and in some lawns weed control becomes a major problem.

Management Of Dry Land Lucerne In The South-West, R Sprivulis

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

MANY dry land lucerne stands have been successfully established in the dairying areas of the South-West.

With good management these can remain productive for many years; poor management can greatly reduce their productive life.

Cotton Bush (Asclepias Fruticosa L.) : Garden Plant Now A Noxious Weed, G R W Meadly

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

THE cotton bush is native to South Africa but is now naturalised in most tropical and sub-tropical countries of the world. Its spread is, in no small measure, due to being grown frequently as a garden subject.

Calotropis Or Rubber Tree (Calctropis Procera (Linn.) Dryand), G R W Meadly

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

TWO SPECIES of Calotropis have been introduced to the northern parts of Western Australia. They are closely related in most respects but differ in one fundamental feature which decides their significance as undesirable plants.

The Control Of Annual (Wimmera) Ryegrass In Cereal Crops, Geoffrey A. Pearce, B. J. Quinlivan

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

The annual ryegrasses are valuable pasture plants in Western Australia, yet have become one of the major weed problems in cereal crops.

The key to cultural control of annual ryegrasses in cereal crops is an understanding of the factors which govern germination of the seed.

Covering the seed with soil keeps out light and provides a more stable moisture supply, bringing about a faster rate of germination. This is the basis of control programmes recommended in this article.

Recommendations for chemical control are also included.

How Profitable Are Herbicides For Weeds In Crops?, J W. Malcolm, G. A. Pearce

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

BEFORE spending money on chemical weed control in crops, a farmer needs to know how profitable the operation will be. He may also be influenced by other things such as the need for weed-free seed, but the most important consideration should be an increased cash return.

If a herbicide is used to control weeds in a crop, the extra yield achieved must be worth more than the cost of the herbicide and its application for the treatment to be profitable.

This article gives guidelines to help farmers estimate the likely profitability of herbicide treatments for quota and non-quota crops.

The Control Of Weeds In Linseed And Rape, Geoffrey A. Pearce

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

Like all crops linseed and rapeseed can suffer from weed competition.

Linseed is highly susceptible to weed competition, while rape is susceptible to the chemicals used to kill broad-leaved weeds, so both crops pose special problems.

As in other broad-acre crops, cultural methods usually provide the best means of weed control.

A Cheaper Herbicide For Wild Oats, Geoffrey A. Pearce

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

A NEW herbicide, *NEOBAN, will reduce the cost of chemical for the control of wild oats in wheat and barley to $2.50 per acre.

Because of the cost of herbicides for wild oats during the past two years, the acreage treated has been declining steadily.

Farmers who thought that spending about $4 per acre was worth while will be delighted with Neoban.

Chemical Cultivation : Its Place In Crop Planting, Geoffrey A. Pearce

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

PROGRESS in the field of chemical weed control has been spectacular in recent years. Despite the cut-back in expenditure on herbicides, the idea of replacing cultivation with chemical sprays is attracting great interest.

Weed Control Research Pays Dividends, G R W Meadly

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

On my bookshelf is a handbook entitled "War on Weeds" or "How to Double our Food Supply."

In many of these countries experiments have been made to ascertain as far as possible the exact damage done by weeds to crops.

Result: In all the experiments, whether made in England or abroad, the mean loss was over 50 per cent.

The level of loss is equally true today, but the methods at our disposal for handling weeds have improved tremendously.

Progress In Research On Noxious Weeds, Geoffrey A. Pearce

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

RESEARCH on noxious weeds has enabled the development of many practical methods for the control of these weeds.

Where the recommended treatments have been accepted by farmers, large scale operations have reduced the areas infested and stopped spread into new paddocks.
