Immersive technologies & their use in agriculture research & extension – Webinar

Immersive technologies webinar

Immersive technologies – 360 degree photography/filming, virtual reality (VR) and augmented reality (AR) use in agriculture research and extension were presented in a recent GRDC Communities Webinar. Guest speakers Matthew Cox (Agriculture Victoria) & Michael Moodie (Frontier Farming Systems) covered and discussed how these technologies can be used for project […]

Fungicide resistance – Back to basics

Fungal disease appearing on crop

The treatment of fungal plant pathogens through the use of fungicide applications is and will remain essential for maintaining healthy crops and reliable high-quality yields. Their use in modern cropping systems form a key component of integrated crop management, and their effectiveness must be sustained as long as possible. Understanding […]

Barley Loose Smut

Main points Barley loose smut infections are becoming more common in varieties such as Spartacus CL, LaTrobe, Rosalind and Hindmarsh. Growers need to ensure that seed of these varieties have good coverage of an effective seed treatment fungicide prior to sowing in 2019. Situation Loose smut continues to be observed […]

Taking stock of what we know about Crown rot

Crown rot has long been present in Australian cropping systems, but the introduction of minimum tillage systems, changing rainfall patterns and increased heat events has meant an increase in the severity and prevalence of this disease. This article looks at the key findings from the recent review Crown rot of […]

Septoria tritici blotch update

Even though 2017 wasn’t particularly conducive to wet weather diseases like Septoria tritici blotch, there were still widespread reports of this disease in crops throughout southern Australia. ‘How we can therefore manage our fungicide use to reduce resistance risk’ was Nick Poole’s key message when he presented at the Adelaide […]

Cucumber Mosaic Virus – sowing healthy seed is critical

Aphid-borne virus epidemics are favoured when a significant source of virus infection is present, and climatic conditions (warm weather, rainfall sufficient for green bridge development) favour aphid buildup. Best management for seed-borne pulse viruses, such as Cucumber Mosaic Virus (CMV) starts with maintaining a healthy seed source. Sowing healthy seed […]

Barley disease yield loss response curves

Yield loss data is often generated by comparing trial plots with high disease levels and plots with no disease. Yield loss figures are then calculated based upon potential yield loss as a percentage of maximum yield in a susceptible variety. In an on-farm situation, disease pressure is more likely to […]
