The Webworm. 1. The Webworm In Its Natural Environment, J A. Button

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

MANY farmers are concerned about the apparent increase in webworm numbers in recent years.

It has been suggested that the problem is now more widespread and the outbreaks more regular than a few years ago.

The Webworm. 3. Ecology : A Report On Some Of The Factors Which Regulate Webworm Numbers In The Field, J A. Button

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

IN this section the webworm will be examined in its environment, and particular attention will be given to the more important factors which govern numbers and distribution of the insects.

Progress In The Control Of Cotton Fireweed, Geoffrey A. Pearce

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

Cotton Fireweed (Erechtites quadridentata) is native to Western Australia and was first collected by Drummond before 1850. In its natural habitat it is quite insignificant and passes unnoticed.

Cotton fireweed, a native perennial plant, has become a serious weed in the south coastal districts and is now one of the most widespread weeds in the State.

The Doublegee, G R W Meadly

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

DOUBLEGEE, like a number of other major weeds, is native to South Africa. It was introduced to Western Australia during the first years of settlement.

There is no more troublesome weed in Western Australia than doublegee. It competes strongly with crop and pasture and its spiny fruits penetrate the hoofs of stock, causing lameness.

ONE of the major problems facing farmers in the South-West of Western Australia is the hazard of bracken fern poisoning.

Bare Patch And Poor Emergence Of Cereals. 4. Quality Of The Seed, S C. Chambers

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

The importance of using fresh good quality grain for sowing wheat crops was emphasised by results obtained in recent plot trials.

Seedling emergence was less for broken, pinched and small types of seed than for large grain and was further reduced with ageing of the seed.

Spraying For Grasshopper Control, T J. Tozer

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

A BIG increase in cereal growing in the "hopper" belt has brought a general improvement in the grasshopper situation over the past few years.

This highlights the emphasis entomologists have placed on cultivation as the best known way of controlling grasshoppers.

Weeds In Lawns. 2. The Control Of Weeds In Lawns, Geoffrey A. Pearce

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

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

To the many people who like to keep a weed free turf it is therefore encouraging to know that nearly all weeds can be controlled with herbicides.

The Webworm. 4. Control Of The Webworm, J A. Button

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

EARLIER articles in this series have provided a broad oatline of the biology, life history and ecology of the webworm.

In this article chemical and cultural methods of control are considered in relation to this background information.

Pruning Citrus Trees, D B. Argyle

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

PRUNING is one of the less important operations in citrus culture but if properly carried out it can contribute to the economy of production and the general wellbeing of the orchard.

A Progress Report On Commercial Cotton Growing On The Ord River Project, William John Toms

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

The recommendations given in this article have been built up from the experience of the author in growing 200 acres of cotton in the Ord River area during the 1962-63 season for the Department of Agriculture, from findings made by Kimberley Research Station, and from discussions with the present farmers in the area.

When a new form of agriculture is introduced into a new area techniques and ideas change rapidly as farmers become acquainted with their new environment and the new crops. The recommendations will therefore require constant revision.

Deep Sowing Of Wheat : The Effect On Root Systems, S C. Chambers

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

DEEP sowing appears to be an important cause of poor emergence in wheat and care should be taken to seed at the recommended depth of 1 to 1J inches.

Nevertheless some growers in drought liable areas, persist in sowing at 2 to 3 inches in the belief that it will encourage a deep root system.

The Mango In Western Australia, K S. Cole

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

ALTHOUGH normally considered a tropical tree, the mango does well in the sub tropics of Western Australia.

The main commercial area in the State is Carnarvon but a few trees grow as far south as Perth.

Wild Oats In Wheat, J G. Paterson

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

Trials with a new chemical suggest that economical control of wild oats in wheat is only possible in heavily infested crops.

I N recent years there has been a marked increase in the incidence of wild oats in the wheat areas of this State. Three factors have been responsible.

Weeds In Lawns. 1. Identification Of Weeds In Lawns, Robert Dunlop Royce

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

ACCURATE identification of weeds is the first principal of weed control with modern chemicals.

This is as true for weeds in lawns as any other weeds.

Take-All Of Wheat On The Esperance Downs, S C. Chambers

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

THE agricultural development of the Esperance Downs was reviewed recently by Shier, Dunne and Fitzpatrick (1963) who indicated the great potential of this region.

They described the establishment of clover ley pastures capable of supporting heavy stocking rates. Crops of oats or linseed also give excellent returns.

Weed-free rotations which include linseed, oats or vetches may reduce wheat losses caused by take-all on the Esperance Downs.
