Bedstraw Eradication Program 2021/22: Annual Report To Grain Growers, Department Of Primary Industries And Regional Development, Western Australia

Agriculture reports

Three-horned bedstraw is a competitive weed that can cause considerable yield loss in crops, and its seeds contaminate fodder and grain. To stop the weed becoming established in Western Australia and impacting production, WA grain/seed/hay growers (via the Grains, Seeds and Hay Industry Funding Scheme) fund the Bedstraw Eradication Program.

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.

Studies On Bean Yellow Mosaic Virus In Pasture Species And Lupins., Simon Mckirdy, R. Jones

Experimental Summaries - Plant Research

Trial 90PE11

Location: South Perth.

A survey was conducted to determine the extent of Bean Yellow Mosaic Virus (BYMV) infection in subterranean clover pastures. The pastures were sampled in October by officers from each of the country districts and from south Perth. 100 samples were collected from each pasture, 1 sample every 5 paces , and sent to south Perth. The ELISA test and the Gibbs and Gower formula were used to determine a percentage BYMV infection for each infected pasture.
