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...

ALL-yeAr-rOund ATTACK On SnAiLS required.. While snails cause problems at crop emergence and harvest, integrated management needs to occur across the seasons... For some growers, the first time they discover that snails are a problem in their crops is when a buyer rejects their grain...

Early research on recently released bread and durum wheat varieties suggests some new varieties may have a more stable yield across wider row spacing... The best results are achieved with row spacings of 30cm or more and using +/-2cm accuracy guidance and autosteer... To establish soil nutrient status in systems using wider row spacing a modified approach to soil sampling is suggested...

avoid surprises when selling stored grain by monitoring for insect pests monthly... Pitfall traps installed in the top of the grain store will show insects are active long before they are seen on the surface of the grain... Protecting any grain stored from insect attack makes economic sense, because even feed grain can lose value though loss of protein or palatability, affecting livestock growth rates...

void surprises when selling stored grain by monitoring for insect pests monthly... Holding the tray in the sunlight warms the insects and encourages movement making it easier to identify them and monitor population numbers... Sieve a sample: Shaking a grain sample on a mesh sieve (2mm) will separate any insects making them easier to identify...

The benefits from separating the real estate (farm land) from the operating business relate to alternative options for farm scale expansion, succession and retirement... , land owners should apply rent to the land to get an ROC. Rent paid by an operating business to the real estate business can account for any opportunity capital cost... While land values have tended to increase steadily at an average of four to five per cent over the long term, operating profits from cropping farms have become more volatile underlying the need for the operating business to leverage the land as security...

KEY poiNtS A range of soil test values used to determine if a nutrient is deficient or adequate is termed a critical range... recent research has highlighted that nitrogen applications can be wasted, even on cropping soils that have low n availability, if the levels of other nutrients such as potassium (K), phosphorus (P) and sulfur (S) are not adequate... The critical wheat soil S test value measured in the 0 to 30cm soil layer is 4.6 (4 to 5.3) mgS/kg for all soils to achieve 90 per_cent of maximum yield...

new strains of powdery mildew have been detected on commercial barley varieties previously considered resistant... if powdery mildew is detected, apply an appropriate fungicide immediately, based on varietal resistance level, growth stage, severity of infection and likely future weather conditions... The second application may only be tebuconazole); or Costs of buying and applying fungicide vary necessary if susceptible varieties have a mix of group 3 dmis and group 11 depending on choice of fungicide and rate been sown...
