Growers in high rainfall zones should be proactive and develop a Barley Yellow Dwarf Virus (BYDV) management plan which includes crop monitoring, green bridge management, foliar pesticide sprays and pre-sowing seed treatment... Trial results have found that the oat and rose grain aphid are found on wheat and barley and the corn aphid favours barley and is rarely found on wheat... Even where there have been large yield losses due to BYDV, trial results have not shown any difference in protein content between sprayed and untreated plots...

The black Portuguese millipede is emerging as a sporadic but damaging pest of broadacre agriculture, particularly canola, while high populations of slaters have damaged some crops in recent years... in the southern region, damage has been reported in the medium and high rainfall zones including near Wagga Wagga and Henty in new South Wales; the mid north, yorke Peninsula and Kangaroo island in South Australia; and the Western districts and Wimmera areas of Victoria... in south-eastern Australia, slaters have caused damage to wheat, oats, canola, lentils and pastures...

EARLY PLANNING KEY TO DIRECT HEADING Many grain growers fear that direct heading canola is risky and that high shattering losses are inevitable... Yield losses due to shattering while direct heading are likely to be lower than yield losses associated with windrowing a crop too early, such as a week or more before 40 to 60 per cent of seeds on the main stem have changed colour... Direct heading is not suited to paddocks with significant variations in soil type and/or topography - factors that affect plant-available water and plant maturity...

direct heading allows for maximum yields if canola is harvested on time and the header is set-up correctly to avoid shattering... yield losses due to shattering while direct heading are likely to be lower than yield losses associated with windrowing a crop too early, such as a week or more before 40 to 60 per cent of seeds on the main stem have changed colour... Direct heading is not suited to paddocks with significant variations in soil type and/or topography - factors that affect plant-available water and plant maturity...

European earwigs have emerged as a pest of increasing significance in the past five to ten years as a result of changes in farming practices... Grain harvested at night is more likely to contain earwigs and require cleaning... If the windrows are harvested using crop lifters, there will be significantly more invertebrates, such as earwigs, present in the harvested grain compared with grain harvested using a belt pick-up front...

Eyespot is a fungal disease that occurs in areas with prolonged cool and damp conditions and yield losses can range from minor to extreme, depending on the amount of lodging in the crop... Spores can survive in plant stubbles for two years or longer if the stubbles have not broken down... Growth regulants can be used to shorten and strengthen plant stems and reduce the risk of infected plants lodging...

To produce the highest quality durum, growers need to develop a management plan which considers agronomic and variety selection as well as understanding the requirements of pasta manufacturers and end users... germination or 'sprouting' starts a complex series of chemical reactions in the grain including an increase in grain alpha-amylase, an enzyme that breaks down starch... durum is assessed for quality on receival with grain segregated according to the quality parameters of dr1, dr2 and dr3...

The black Portuguese millipede is emerging as a sporadic but damaging pest of broadacre agriculture, particularly canola, while high populations of slaters have damaged some crops in recent years... Black Portuguese millipedes (left) and slaters (right) generally feed on organic matter their populations and the incidence of crop attack has increased in recent years... In south-eastern Australia, slaters have caused damage to wheat, oats, canola, lentils and pastures...

Brown manuring of pulse crops is becoming an increasingly popular tool for weed management, particularly where there is herbicide resistance, and for boosting reserves of soil nitrogen for use by the following crop... Pulses should be brown manured by either spraying out in early spring, to coincide with the critical growth stage of the weed, or waiting until plants reach peak biomass to maximise nitrogen fixation... To maximise nitrogen fixation, and maximise biomass, additional costs in fertiliser and herbicides may be required...
