• New hand-held infrared instruments have shown promising results for use in predicting crop nitrogen (N) content of wheat and barley in the field. • New spectroscopic tools offer improved non-destructive predictions of N compared to normalised difference vegetation index (NDVI) and other available tools. • Accurate and robust predictive NIR calibr...

• The Australian agvet regulatory system is a scientific, evidence-based risk assessment process which is highly recognised internationally. • Agvet chemicals are nominated for review based on key criteria of concern including human health (toxicology and occupational health and safety), environment, residues and trade, target crop safety and effic...

• Burial of weed seeds under chaff can reduce seedling emergence, but the amount of suppression depends on weed type, chaff type, and amount of chaff cover. • There is no evidence as yet that weed seeds rot more quickly in chaff tramlines, but it is likely environmental conditions and weed seed type could make a difference. • Stripper fronts and co...

• Drought in 2018 and low summer rainfall are likely to increase the risk of rhizoctonia root rot and crown rot in 2019. Identify paddocks at risk prior to sowing using PREDICTA® B to implement strategies to minimise yield loss. • Cereal cyst nematode (CCN) levels have increased in SA with detections in 24% of paddocks tested in 2018, compared to 1...

• Effective snail baiting requires applying baits at the right time and at sufficient pellet density to ensure good encounter rates. • Bait in autumn as soon as snails become active and before they lay eggs, check spreader calibration, apply an adequate rate and select an appropriate product for the field conditions....

• Select a grain storage option that provides flexibility to meet market requirements. • The only silos suitable for fumigation are gas-tight (meeting AS2628-2010), pressure tested. • Hygiene and monitoring are keys to maintaining grain quality in storage. • Aeration is an effective tool worthy of consideration – best paired with an automated cont...
