Control Of Mediterranean Fruit Fly (Medfly) In Backyards, Sonya Broughton, Francis De Lima

Bulletins 4000 -

The Mediterranean fruit fly, Ceratitis capitata (Medfly) is thought to originate from tropical Africa. It is a pest in many areas of the world including Western Australia. It was first detected at Claremont in 1895 and is now found as far south as Esperance and as far north as Derby. The main area of infestation extends from Carnarvon to Bunbury.

Cucumber Mosiac Virus In Lupins, Annette Bwye, Roger Jones, Wayne Proudlove

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

Cucumber mosaic virus is a threat to lupin crops from Geraldton to Esperance, particularly to those growing in areas receiving more than 400 mm average annual rainfall. The disease markedly decreases grain yield in narrow-leafed and yellow lupins but doesnot infect albus or sandplain lupins. Worldwide , after bean yellow mosaic virus, cucumber mosaic virus is the second most important virus affecting lupins. Annette Bwye, Roger Jones and Wayne Proudlove outline the symptoms, spread and management of this serious disease.

Analysis Of Black Point In Wheat, J M. Wilson

Technical Bulletins

Fungal staining (black point) of wheat can reduce the quality of grain. The most serious problem is a discolouration of products. Discolouration is a consequence of infection by microorganisms. The most likely cause in Western Australia is a species of the common fungus Alternaria. Infection and discolouration occur between flowering and grain maturity, and the optimum environmental conditions are probably consecutive days of high relative humidity together with warm temperatures.

On The Trail Of The Native Budworm, Kevin Walden

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

Native budworm, the worst pest of lupins, is a bit of a uiill-o-the-unsp. Some years the native budworm moths go virtually unnoticed. In others, they appear in plague proportions without warning - in these years, the cost to growers in lost yield runs into millions of dollars.

If an early warning system can be developed to predict the extent of moth flights into lupin crops, and this seems possible, major crop losses could be averted.

The Department of Agriculture has started research to develop a system of predicting the size of spring flights of native budworm moth. We need to …

The Queensland Fruit Fly Eradication Campaign, G P. Ayling

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

Western Australia has started an extensive eradication campaign against the Queensland fruit fly, one of the worst horticultural pests in the world.

The programme, the largest of its kind in Australia, and one of the biggest in the world, involves the integration of three tequniques for fruit fly control: lure trapping, protien baiting and the release of sterile male flies.

Potato Cyst Nematode, J M. Stanton

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

For many years, Australia has been the only large land mass in the world in which potato cyst nematode has not been found. However, in 1986, potato cyst nematode was found on four properties at Munster 10km south of Perth, Western Australia.

Potato cyst nematode is a minute worm like organism which attacks the roots of several plant species including potatos, causing very high yield losses. It is a very serious pest of potatoes throughout the world and strict quarantine controls are enforced in countries and potato-growing areas froo of nematode.

Rhizoctonia Patch Of Cereals, G C. Macnish

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

Rhizoctonia patch is now widespread within Western Australia, having been recorded on all cereals and on a wide variety of other crops and pasture plants. Although the disease-as its name implies - looks spectacular in the field, the overall reduction in crop yield is probably small. However, its increasing frequency is causing considerable concern as the disease appears to be associated with minimum or reduced tillage systems.

Ryegrass Toxicity Organism Found On Other Grasses, D L. Chatel, J. L. Wise, A. G. Marfleet

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

Yellow slime disease caused by Corynebacterium sp. has recently been found in three grass species.

The diseased grasses were found in the field growing with each other and with affected toxic annual ryegrass.

Controll Of Eelworm Diseases Of Bananas In Western Australia : A Review, O M. Goss, M. G. Hawson

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

During the 1950's, a decline in bananas in plantations in Carnarvon, caused by heavy infestations of eelworms, prompted investigations into eelworm control.

The work was started in 1955. The results and recommendations based on experiments have been published in Department of Agriculture Bulletin 3532.

Diseases Of Clovers In Western Australia, W A. Shipton

Leaf rust occurs infrequently and has not been known to cause serious damage.

Citrus Red Scale Control, G D. Rimes

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

THE RED SCALE (Aonidiella aurantii Masc.) is widely distributed throughout the world and is a serious pest in countries with semi-arid climates such as California, South Africa, Palestine and Australia.

The home of the pest is probably China, but it has been known in Australia for over 70 years and it was introduced into North America from the continent.

Daffodil Eelworm Diseases, O M. Goss

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

EELWORMS or nematodes are minute worm-like organisms, some of which cause plant diseases.

The plant parasitic forms are not visible to the naked eye but the damage resulting from their attack can be quite severe.

Removing Sooty Mould On Oranges, Department Of Agriculture, Western Australia

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

SOOTY Mould is one of the most common and most disfiguring blemishes on oranges.

A chemical dipping treatment has recently been perfected by a joint effort of the New South Wales Department of Agriculture and C.S.I.R.O.

Plant Diseases : Armillaria Root Rot Of Fruit Trees, R F. Doepel

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

Armillaria root rot is a fungal disease capable of causing serious damage to both young and established orchards.

Although outbreaks are usually localised, eradication of the fungus and replacement of affected trees can involve the grower in considerable expense. For new plantings, thorough clearing of the land is recommended for preventing losses from this disease.

Fruit Fly Control With Rogor 40 And Lebaycid : Progress Report, D G. Shedley

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

THE Mediterranean fruit fly has been present in Western Australia for over 60 years and during that time many types of insecticides have been tested against the pest.

Traps and lures were amongst the earliest control measures adopted, but these gave way to sugar solutions poisoned with such materials as arsenic and sodium fluosilicate.
