Eyespot of winter cereals – interview with Marg Evans

Marg evans discussing eyespot

We interviewed Marg Evans from SARDI about Eyespot, a fungal disease of cereals which occurs in medium and high rainfall zones. The disease has been known to occur in paddocks in New South Wales and South Australia for many years.  In this short video Marg discusses symptoms, management and current […]

Eyespot of winter cereals – an emerging disease

Eyespot is a fungal disease of cereals which occurs in medium and high rainfall zones and has been known to occur in paddocks in New South Wales and South Australia for many years. More recently, with changes in farming systems, eyespot has been causing increasing problems in South Australia. In […]

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 […]

Diagnosing plant diseases: What do we ask and why do we ask for it?

Diagnosing a plant disease or other injury is like going to a medical doctor who must ask several questions before making an accurate diagnosis and recommending a treatment. If you withhold information, it can lead to a misdiagnosis. The same goes for crop diseases. Plant pathologists, specifically diagnosticians, are often […]

Blackleg Management Guide

Blackleg lesions on canola leaf

Blackleg is a fungal disease of canola that can cause severe yield loss. It is more severe in areas of intensive canola production as fungal spores are released from the previous year’s canola stubble and spread by wind and rain splash. With good management yield loss can be minimised. The blackleg management guide […]

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 […]
