Although a high-risk crop, oaten hay has the potential to outperform all other cereals with respect to gross margins... The widespread use of genetic analysis in agriculture is limited by economic factors... In the short term, fungicides used at seeding (seed dressings or applied in-furrow with fertiliser) and foliar fungicide sprays will mitigate risk and minimise losses...

Mention of a trade name or company in this publication does not imply endorsement of any product or company by the Department of Agriculture and Food, Western Australia... Overall, 60-70 per cent of flour is used in traditional flat breads, 20-25 per cent of flour is used in western style breads and 5-10 per cent is used in cakes and biscuits... In summary, canola varieties sown 2-3 weeks earlier than normal (early to mid April) can be grazed in winter prior to bud elongation (usually providing 600-800 dse grazing days/ha) and recover with no impact on yield or oil...

KEYMESSAGES Incorrect use of phosphine since the 1950s, has led to escalating resistance in stored grain insects which threatens the continued use of phosphine at the farm level... In summary, canola varieties sown 2-3 weeks earlier than normal (early to mid April) can be grazed in winter prior to bud elongation (usually providing 600-800 dse grazing days/ha) and recover with no impact on yield or oil... When running a trial it is important to: 1...

The arrival of the previously undetected Russian Wheat Aphid (RWA) in the southern cropping region has heightened the need for correct identification of aphid species present in this year's crops... The publication now includes information on RWA which was detected in Australia for the first time in May this year and is now established in a number of cropping regions in South Australia and Victoria... Identification of crop aphids is very important when making control decisions and the Back Pocket Guide is designed to assist growers and agronomists in their efforts to correctly identify species observed in crops, this year and beyond...

The aim of the project was to clone the scald resistance gene Rrs1 from barley and identify more resistant barley germplasm that is not used by barley breeders... Results show that Rrs1 resides at a genome region hosting a suite of 10-14 similar genes that are candidates for resistance genes against different scald pathotypes... The aim of the research is to generate molecular tools that allow the identification of scald infection objectively (no subjective scoring) and significantly earlier than the appearance of leaf symptoms...

The continuous cropper, who has properties 50 kilometres east of Pingelly and 30km east of Corrigin, says towing a chaff cart has helped reduce the ryegrass seedbank... At east Pingelly in 2010, several barley paddocks sown close to 22 April went on to average 2.5 tonnes a hectare, whereas those planted around 24 May averaged 1.5t/ha. ".. Lance waits for clear weather and a light breeze before setting fire to the wheat dumps at about 4.30pm. He says this is important to help to prevent willy-willies from picking up sparks and moving them to surrounding paddocks...
