All other publications

The small lucerne weevil, Atrichonotus taeniatulus, has caused considerable damage to lucerne and subterranean clover in recent years. This study reviews the taxonomy of the insect, the damage it causes and the various stages of its life cycle


Virus, Viroid, Mycoplasma And Rickettsial Diseases Of Plants In Western Australia, L K. Price, George Mclean Jan 1984

Virus, Viroid, Mycoplasma And Rickettsial Diseases Of Plants In Western Australia, L K. Price, George Mclean

Technical Bulletins

Provides details of the virus, viroid, mycoplasma and rickettsial diseases recorded on plants in Western Australia. To establish these records, a range of tests have been used including sap transmission; leaf dip electron microscopy; aphid transmission and serology. The authenticity for each record is noted in the list of pathogens.

Clover, Bluegreen Aphid And Red Legged Mite Screening, Medicago Murex Evaluation, D J. Gillespie Jan 1984

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. …
