Environmental Weed Risk Assessment Protocol For Growing Non-Indigenous Plants In The Western Australian Rangelands, Geoff A. Moore Mr, Christine Munday Ms, Papori Barua Dr

Bulletins 4000 -

This bulletin is a post-border environmental weed risk assessment (WRA) protocol which is based on the Environmental WRA Protocol developed for the Future Farm Industries Co-operative Research Centre (FFI CRC), but with some changes to reflect the different environment and objectives.

The WRA protocol was developed specifically as a post-border assessment of non-indigenous species that may have agricultural value in the WA rangelands and the risk that they may become environmental weeds. Weeds can occur in many land-use systems including agriculture, horticulture and forestry; however, the focus of this protocol is on the risk that non-indigenous agricultural plants may become …

Mosaic Agriculture: A Guide To Irrigated Crop And Forage Production In Northern Wa, Geoff A. Moore Mr, Clinton K. Revell Dr, Christopher Schelfhout Dr, Christopher Ham Mr, Samuel Crouch Mr

Bulletins 4000 -

The Bulletin is a comprehensive guide for pastoralists, agronomists, agribusiness and the broader community on the growing of irrigated crops and pastures within a rangeland pastoral setting.

Dispersed irrigation developments on stations throughout the northern rangelands (sometimes referred to as mosaic agriculture) has created opportunities for the introduction of more productive forage species and pastoralists can now grow high quality forage for 12 months of the year. This can help to overcome the key constraint of traditional pastoral systems, the low quality of the feed over the dry season that typically results in stock losing condition.

Plant Diseases Impacting Oaten Hay Production In Australia - A Review, Kylie Chambers, Geoff J. Thomas

Bulletins 4000 -

In Australia, there are a range of fungal, bacterial and viral pathogens that infect oats, impacting on yield and quality of grain and hay crops. The overall impact of these diseases on oaten hay production is not well researched or understood, especially compared to that of other cereal crops. Export hay is evaluated on physical qualities such as stem thickness and greenness and nutritional qualities including water-soluble carbohydrates, neutral detergent fibre, acid detergent fibre and dry matter digestibility. The colour/ greenness of oaten hay can be reduced by disease lesions, chlorosis and saphrophytic fungi growing on dead tissue all of …

Root Disease Under Intensive Cereal Production Systems, Bill Macleod, Vivien Vanstone, Ravjit Khangura, Ciara Beard

Bulletins 4000 -

This Bulletin describes symptoms and control methods for the most commonly encountered cereal root diseases in Western Australia:

• rhizoctonia bare patch

• root lesion nematode

• take-all

• fusarium crown rot

• cereal cyst nematode

• common root rot

• pythium root rot

Diseases caused by pathogenic micro-organisms can significantly reduce the yield of cereals. Some of these diseases are uncommon while others occur over a large area of the Western Australian wheatbelt every year. The most prevalent root diseases of cereals in Western Australia are rhizoctonia bare patch, root lesion nematode and take-all. Less widespread are fusarium crown rot, cereal cyst nematode, common root rot …

Managing Blackleg : A Grower's Guide To Minimising Risk From Blackleg Disease Of Canola In Western Australia, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Blackleg is spread primarily by wind, with the heaviest spore fall out normally occurring within 500 metres of any canola residue. Each year canola residue continues to produce blackleg spores at a diminishing rate until the stubble has completely broken down (see Diagram 2). In WA this breakdown could take up to 4 years, and so the recommendations are for long rotations.

The blackleg fungus can attack all the aerial parts of the plant. While leaf infection is the most obvious symptom, high levels of leaf infections do not necessarily indicate that major losses will occur from blackleg. It is …

Clover, Bluegreen Aphid And Red Legged Mite Screening, Medicago Murex Evaluation, D J. Gillespie

Experimental Summaries - Plant Research

Clover scorch: In spite of poor seasonal conditions, adequate levels of clover scorch developed in the test plots to readily identify susceptible clovers. Of the 333 introductions tested, 23% scored 3.0 or less indicating a high level of resistance. Bluegreen aphid screening: Two hundred and twenty four randomly selected subterranean clovers from all Western Mediterranean collections were tested for resistance to BGA in Nov/Dec of 1983. The susceptibility of annual legumes to Bluegreen aphid. Red legged earth mite screening: Results of two preliminary experiments to develop techniques for mass screening for RLEM resistance in subterranean clover were reported last year. …
