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 • Baiting efficacy requires adequate pellet densities (30-60m2). • To minimise bait degradation, avoid baiting in significant rainfall or high temperatures and consider bait storage temperatures. • Sound, evidence-based science is reinforcing the best practice management: baiting efficacy is higher earlier in the season than in s...

Low-cost, low risk seeder-based strategies produced valuable benefits to wheat/barley establishment and grain yield in a severely water repellent sand in two below-average rainfall seasons. Several products and application strategies provided consistent and large crop establishment benefits over two years at the same site, while also producing up ...

Take home messages • Subsurface acidity and stratification are emerging as serious constraints to crop production across NSW, Victoria, SA and WA. Identification and treatment is being explored through multiple GRDC and State and Federal government investments. • Traditional soil sampling strategies can lead to misdiagnosis of subsurface issues;...
-
Recent Australian wheat cultivars are heat tolerant. However, new materials developed from diverse genetic backgrounds using field-based phenotyping and genomic selection suggest that levels of heat tolerance can be substantially improved....

Take home messages • The efficacy of the herbicide mix; clethodim and butroxydim is significantly greater than either clethodim or butroxydim when applied stand-alone. • The efficacy of the herbicide mixture; trifluralin and prosulfocarb is significantly greater than either trifluralin or prosulfocarb when applied stand-alone. • There is little or ...
-
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 • Future Farm is a large multi-institutional project which seeks to improve nitrogen (N) fertiliser decision making through the automated use of crop and soil sensors and other on- and off-farm data sources. • Early results from the field-based component of the research confirms the idea that an N fertiliser decision is a multiva...
-
Take home messages: • Group B resistance in sowthistle and prickly lettuce in the southern region is common. • Resistance to the imidazolinone herbicides (IMI) in these weeds is increasing and is a major issue for management in IMI-tolerant lentils. • Resistance status of target weeds can affect control in the current and following season. • Manage...
-
Take home messages • Group B tolerance traits are now commercially available in lentil and faba bean. • There are several emerging technology and genetic traits being developed, including target site tolerance traits to different modes of action (Group C and Group I). • Integrated weed management strategies are critical to sustainable farming syste...
