Managing Lupin Anthracnose, Greg Shea, W A. Cowling, B J. Burchell, D Luckett, H Yang, Mark W. Sweetingham, Geoff J. Thomas

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

Anthracnose in lupins was first reported in commercial crops in Western Australia in September 1996. By October 1996, several thousand lupin breeding lines and wild types of 11 lupin species were sown in New Zealand for resistance screening. In 1997, resistance to anthracnose was confirmed in several breeding fines and commercial cultivars of narrow-leafed lupins (I. angustifolius), landraces of albus lupins (I. albus) and wild types of several other lupin species. Important information on critical seed infection levels and fungicide seed treatment has also been determined.

Carrot Export Growth Depends On Keeping Cavity Spot Under Control, Allan Mckay, Elaine Davison

Pulses : Profitable New Crops For The Wheatbelt, Kadambot Siddique, Stephen Loss, Ian Pritchard

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

Narrow-leafed lupins have beeb produced on sandy acid soils throughout the wheatbelt for more than two decades. However, the wheatbelt contains large areas ofsoilsnot suited to narrow-leafed lupins. For several years reasearchers have been examining alternatives to narrow-leafed lupins for these soils.

Kadambot Siddique, Stephen Loss and Ian Prichard look at production of these new grain legumes, known as pulses.

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.

Merging Conservation With Production In Remnant Bush, Anne Morgan, Alison Fuss

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

Exports of cutflowers and foliage from Western Australia are now worth about $17 million a year. A third of this is picked from the bush, either on Crown Land or areas of remnant bush on private property. While the industry's future lies in cultivation, bush picking is likely to remain important for some years. This can provide both extra income for farmers and benefit the environment - as long as care is taken

Barley Yellow Dwarf Virus In Cereals, Simon Mckirdy, Roger Jones

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

Worldwide, barley yellow dwarf virus (BYDV) is the most widespread and damaging virus disease of cereals. It infects wheat, barley, oats and grasses and is transmitted by several aphid species. The virus is not seed-borne and to persist from one growing season to the next it must survive in over-summering grasses.

Barley yellow dwarf virus decreases grain yield and also causes shrivelled grain. Yield loss is greatest from infection early in the growing season.

Eradication Of Apple Scab, John Cripps, Ralph Doepel

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

The detection of apple scab in two orchards at Pemberton and New/ands in December 1989 ended Western Australia's 41-year, scab-free span for apple growers .

Without eradication orchardists would have had to apply up to 20 fungicidal sprays a year, at an annual cost of $1-2 million, to be able to market a high proportion of scab-free fruit. The industry chose eradication as the cheaper alternative, but the location of infected orchards at Pemberton in particular, with its high rainfall, suggested that it would be difficult .

Scab, or black spot, is the most serious fungal disease of apples in …

Three New Late-Midseason Subterranean Clovers Released For High Rainfall Pastures, Phil Nichols, Donald Nicholas

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

Three new subterranean clovers - Denmark, Gou/bum and Leura - have been released in 1992 by the National Subterranean Clover Improvement Program. These subterranean clovers are black-seeded, have low oestrogen levels and improved disease resistance. Their release offers the potential for substantial improvements in pasture productivity in areas of southern Australia that have long growing seasons.

This article outlines some of the testing procedures and subsequent selection of these varieties and describes their characteristics and potential role in Western Australia.

Coping With Brown Spot And Root Rots Of Lupins, Mark Sweetingham

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

There is increasing concern that brown spot and root diseases may limit the long term viability of lupin cultivation in close rotations in the agricultural areas of Western Australia. Research has found several useful strategies to reduce the impact of brown spot and Pleiochaeta root rot so that losses can be kept to a minimum. Rhizoctonia has proved more difficult to combat. Although less widespread than Pleiochaeta, it has caused severe losses and appears to be increasing in incidence, particularly in the northern wheatbelt. Research has vastly expanded our knowledge of the strains of Rhizoctonia present in our soils and …

Breeding Phomopsis-Resistant Lupins, John Sylvester Gladstones

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

The release of Gungurru and Yorrel lupins marks the coming of age of the narrow-leafed lupin as a crop plantt. These are the first cultivars of the species th have substantial resistance to Phomopsis stem blight, which will make the stubbles much safer for grazing stock.

This article describes the new lupins, their background, and how they were bred. It also acknowledges the contributions of colleagues who helped in important ways.

Breeding Field Peas : Screening Pea Lines, G H. Walton

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

The early use of field peas in Western Australia was as a green manure crop or to feed stock be grazing the mature crop. Varieties which produced a large bulk of green material were sown. There was no control over insects or diseases.

In 1985, the Feseral Government recognised that to realize the potential of grain legumes grown throughout Australia, more research was needed.

One of the Grain Legume Research Council's (GLRC) priorities is species evaluation and variety improvement.

Since 1983, the Western Australian Department of Agriculture has screened advanced crossbred lines from the South Australian breeding programme for its …

Phomopsis Infection Of Lupin Seed, D S. Petterson, P. Mcr. Wood

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

Early reports of lupinosis in Western Australia implicated infected stems and leaves of the sandplain or W,A. blue lupin (Lupinus cosentinii) as the main source of toxicity.

After the introduction of low alkaloid varieties of L. augustifolius, lupinosis continued to oddur on stubbles but random testing of seeds showed only low levels of Phomopsis leptostromiformis infection.

However in 1976, scientists at the University of Western Australia who were evaluating the use of an all lupin seed ration for drought feeding sheep encounted lupinosis in one of their trials.Seven per cent of the seed used was found to be infected …

Barley Breeding Update, P A. Portmann

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

Barley production in Western Australia has increased over the past few years, peaking at 1.42 million tonnes in 1984. The European Economic Community, however, has flooded world markets for barley and over half of ourbarley was sold for feed to Saudi Arabia last year. Current prices therefore have declined as has the total area sown to barley in this State.

Despite this, the potential to increase barley yields is most promising. The Department of Agriculture has cross-bred lines in advanced stages of field testing which could increase yield by 10 per cent across the agricultural areas.

In the longer term, …

The Stripe Rust Threat, B R. Whan, T. N. Khan

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

The wheat disease stripe rust caused crop losses estimated at $20 million in New South Wales during an epidemis in 983. Economic crop losses were reported in neighbouring States and as far westas Ceduna in South Australia. In some States large areas were sprayed with fungacide at considerable cost to control disease spread.

Wheat stripe rust has not been found in Western Australia yet, but all current evidence indicates that it will eventually reach this State.When it does, it has the potential to cause considerable crop losses every year, unlike the spasmodic losses from stem rust, and it will greatly …

Cotton Fireweed : Potential Poison : Research Roundup, J Dickson, R. Hill

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

Although long known as a potential toxic species because of its content, and although it is widely distribuited in all Australian States, cotton fireweed has not generally been consdidered toxic because it is unpalatable and not usually eaten by stock.

In 1973 cattle deaths occured near Ravensthorpe which led to research into Senecio quadridentatus (cotton fireweed).

The plant must be seen as a potential toxic species in situations where the lack of other feed forces cattle to eat the normally unpalatable cotton fireweed.

Experimental Summaries - Plant Research

The Effect of Septoria nodorum on Yield of 125 Wheat Cultivars. The aim of this experiment was as described for that of 1976. There were some modifications to the treatments which were as follows: (a) Most of the cultivars were 'new' and (b) Three levels of Septoria attack were set up:- 1. Low: cover sprayed throughout the season with the fungicide Difolatan. 2. Moderate: inoculated with Septoria three times, followed at heading out by cover spraying with Difolatan. 3. Severe: inoculated four times no fungicide. The 125 entries were sown as hill plots with the three Septoria environments as main …

Subterranean Clover In W.A. 1. The Current Situation, B J. Quinlivan, C. M. Francis

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

From small beginnings some 50 or more years ago subterranean clover has come to dominate the pasture scene in Western Australia. Of the 7 000 000 hectares of sown pasture all but some 500 000 are sown to subterranean clover. Further, it is estimated that there remains an area of similar size still to be sown, although in some instances these future sowings will be possible only if suitable varieties are available.

Clearing and pasture development within the various agricultural regions of the State took place, as a rule, within quite clearly defined time intervals and the varieties selected for …
