Take home messages • It is a legal requirement to follow all label directions when applying any chemical. • There are different perceptions and legal/contractual requirements of key domestic and export markets for chemical residues. • There are market access implications when using chemicals; applying a chemical according to label directions does n...

Take home messages • Frost damage can be detected through sensing but cultivar, plant component, canopy structure and time after frost affects the spectra. Consequently, there are some approaches that look promising but there is currently no unique index that can consistently detect frost damage. • Temperature variation within canopies due to canop...

Take home messages • Applying a single frost to wheat at flowering reduced yield by 7% for every degree below zero (up to -4°C), however, this increased to a reduction by 12% for every degree below zero when applied over two consecutive nights (up to -3°C). • Remote sensing spectral indices including normalised difference vegetation index (NDVI), n...
-
Take home messages • Resistance to pre-emergent herbicides is increasing across southern Australia. • New pre-emergent herbicides are becoming available; however, it is vital that these are used appropriately to get the best results. • Rotating pre-emergent herbicide modes of action and using other weed management practices will be essential to man...

Take home messages • iMapPESTS is a proof of concept research project enabled by a multifaceted industry, research and government network; including GRDC. • Through state-of-the-art surveillance and diagnostics tools and techniques, iMapPESTS aims to demonstrate how on-farm plant pest management can benefit from rapid and accurate monitoring and re...

Take home messages • The response of weed density to delayed sowing is influenced not just by the weather conditions, but also by the seed dormancy attributes of the weed populations. Less dormant weed populations tend to emerge quickly after the opening rains, and they can be managed well by moderate delays in sowing. However, much longer delays i...

Take home messages • Blackleg crown canker results from infection during early seedling growth. Prior to sowing, use the BlacklegCM decision support tool to identify high risk paddocks and explore management strategies to reduce yield loss. • New succinate dehydrogenase inhibitor (SDHI) seed treatment fungicides have higher efficacy, increased lon...

Take home messages • Adult European earwigs are present all year, but eggs and juvenile earwigs are only present from April to November. • European earwigs can cause significant damage to canola, lucerne, lupins and in some cases, lentils. • The potential for damage to emerging crop seedlings by adult European earwigs exists, although it is depende...
-
Take home messages • Canola has a deep root system that can penetrate soil faster (~2cm/day) and for longer than wheat. • Earlier sown, slower developing canola crops can access deep stored water to out-yield later sown varieties if subsoil water is available, AND the spring is dry. • Managing crop sequence and summer fallows to improve deep-stored...
