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.

Trial 90BA12, 90WH17, 90A6, 90MT13

Location: Badgingarra, Wongan Hills, Avondale and Mt Barker.

Cucumber Mosaic Virus - Effect of different levels of infection in seed sown.

Trials were done at Badgingarra and Wongan Hills in which plots were sown with seed of cv. Gungurru which transmitted CMV at rates of 5,, l' and O,. The plots were separated by 30 m wide cereal buffers. The intended plant density of 45 plants/sq m (seeding rate 80 kg/ha) was not achieved at either site because of non-wetting soil problems (Table 1). Establishment of CMV infected seedlings as opposed to healthy ones was …
