Bacterial blight survey to inform breeding efforts

Symptoms of bacterial blight on Kaspa field peas grown at Horsham, Victoria

Following on from samples submitted in 2017 & 2018, researchers are again this year requesting industry to submit green field pea samples infected with bacterial blight from all pea growing regions. These samples will help researchers understand the prevalence of the pathovars within the bacterial blight pathogen population. Bacterial blight […]

Sclerotinia in Victorian Pulses

This season, Sclerotinia white mould, has been found in lentil and chickpea crops in several districts throughout the Victorian Mallee. The prolonged damp conditions throughout winter have favored disease development. Other pulses, including faba beans, vetch and lupins, can also develop sclerotinia white mould. Sclerotinia white mould is a sporadic […]

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 […]
