Climate trends mirrored in sowing decisions.. On our existing two properties, we have 260 to 280 hectares in each rotation, starting with canola, then barley, linseed, wheat, then back to canola... This year we have put in wheat, barley, rye, lupins, field peas, vetch and lentils in a 70 per cent cereal/30 per cent legume ratio...

A reliable, accurate and sensitive RT-PCR test for detecting Wheat streak mosaic virus (WSMV) in bulk samples of wheat seed was successfully developed, validated in blind studies and made available to the agricultural industry through AGWEST Plant laboratories for use in testing seed stocks... The three main ways to combat WSMV are to 1) destroy the green bridge before sowing to prevent transmission of the virus by the WCM, 2) use wheat seed stocks that have either none or only low levels of the virus, and 3) to sow crops late when temperature conditions are non-conducive for WCM... In an early seed transmission experiment, WSMV was detected by RT-PCR in seedlings nine days after sowing and the number of positive seedlings increased considerably over the following six weeks until almost all batches tested positive...

Use of the test may also help to prevent wheat breeders sowing infected seed stocks... Use of the test confirmed widespread occurrence of WSMV in the WA grainbelt and identified the disease for the first time in Tasmania... The research also showed that Australian WSMV isolates represent a single incursion from overseas and the virus has been present in Australia for at least 15 years...

Mention of a trade name or company in this publication does not imply endorsement of any product or company by the Department of Agriculture... The very different scenario that emerged in NSW with widespread infection in 2005 compared with the previous smallscale detections in 2003 and 2004 has highlighted the potential of this exotic pathogen, initially considered to be relatively benign, to cause major losses when conditions favour its epidemics... Nitrogen management also needs to be right, soil needs to be tested and rates applied ...

Caption : Wheat struggling to emerge at Mullewa when sown deeper than 100mm... "One of the research findings was that wheat crop emergence from deep sowing improved when large seed was used, as seed size affects the length of the coleoptile - which covers the emerging shoot," Dr French said... "At Buntine, seed size did not affect crop emergence and yields when wheat was sown at 40mm, but small wheat seed reduced yields by an average of 12 per cent when sown deep at 75mm...
