Insecticide resistance issues continue to outpace novel control options. • Redlegged earth mite (RLEM): o Resistance in RLEM has been detected for the first time in eastern Australia. o Synthetic pyrethroids (SPs) are completely ineffective against SP-resistant RLEM populations, while some efficacy remains for organophosphates (OPs) against OP-res...

Calculating plant available water content (PAWC) can be challenging and it can vary from year to year depending on crop growth. Normalised difference vegetation index (NDVI) imagery is starting to give a good indication of evapotranspiration change across a field. New sensors, such as canopy temperature and 10m towers for inversion monitoring, are ...

Higher yields are possible in new barley varieties; RosalindA and RGT PlanetA in the high rainfall zone (HRZ) with contrasting yield structures. There is opportunity to exploit variation in variety phenology of barley to maximise yields....

Annual ryegrass with resistance to the Group D, J and K pre-emergent herbicides will make management in cereals difficult. Indian hedge mustard populations have resistance to Group B, C, F and I herbicides, greatly reducing control options in break crops. Crop competition coupled with pre-emergent herbicides can be an effective management option....

Time of sowing experiments demonstrated benefits from matching sowing date to variety phenology. Optimal start of flowering time provides a target range for flowering to start within, to minimise frost/heat/water stress and maximise yield for a particular environment. Once the development triggers/phenology for a variety are understood an optimal s...
