• An assessment of current ‘rules of thumb’ (RoT) for predicting nitrogen (N) fertiliser requirements in the southern region cropping systems has identified the need to update current assumptions. • Deep soil N testing prior to (or just after) sowing is critical for good fertiliser N management. • Current RoTs and other decision support systems fo...
-
• Everyone has a role to play in agricultural debates in Australia. • The gap between science and the public discourse must be filled with credible evidence to ensure access to key agricultural production tools. • Every independent, science and risk-based regulatory agency has comprehensively evaluated glyphosate and found it safe, when used accor...
-
• Herbicide Mode of Action (MoA) classifications will be updated to align with the new globally aligned system. • The science hasn’t changed – just the classification codes on product labels and literature will change from a letter to a number. • Continue to follow current integrated weed management strategies and rotation plans. • More information...
-
• A new DNA soil testing service, PREDICTA® rNod has been developed to measure Group E and F rhizobia numbers in soil to assist growers to identify the need to inoculate field pea, faba bean, lentil and vetch crops. • PREDICTA rNod is available to South Australia (SA) and Victoria (Vic) growers via PREDICTA® B accredited agronomists in 2021 and wil...
-
• Glyphosate resistance in annual ryegrass continues to increase. • There are ways to optimise glyphosate efficacy. • Partner glyphosate with other herbicides to improve weed control. UCS00020...
-
• Optimising flowering time of wheat and barley cultivars is one of the most cost-effective ways for growers to maximise yield. • The National Phenology Initiative (NPI) is improving Agricultural Production Systems sIMulator (APSIM) Next Gen so that it can accurately predict cultivar phenology classification and optimal sowing dates across Australi...
-
• The canola industry has become more reliant on fungicides to control blackleg, in some regions there is reduced emphasis on cultural practices to reduce disease. • The decision to use a fungicide is not clear cut and should be based on the disease risk profile of the crop. • Severe blackleg crown canker occurs when plants are infected during ear...
-
• Grain yield losses in vetch of on average of 26% were observed in plots with no disease control. • Selecting resistant varieties and applying foliar fungicides will reduce grain yield losses....
-
• Choose the species of vetch and variety depending on your end goals, or desired end-use. • Each vetch species requires different management and agronomy to achieve optimum production. • There is no ‘one size fits all’ approach with vetch, the diversity of end-uses and environments in which vetch is grown, require different agronomic approaches an...
-
• New registrations for Group G herbicides are expanding the ways these herbicides can be used. • The choice of a spike with knockdowns should be based on activity against the most problematic weeds. • Care needs to be taken with pre-emergent applications in light soils and where crop tolerance is not high to keep the herbicide out of the crop row....
