Blackspot Manager is a forecasting model for ascochyta blight (synonym: blackspot) of field peas. It can be used by agronomists and growers to help identify the best balance between early sowing and potential yield loss from ascochyta blight. Windborne ascochyta spores are released from infected stubble early in autumn, with […]

Don’t turn your back on ascochyta in pulses despite dry

Ascochyta in lentils

Dry conditions across the medium and low rainfall zones in South Australia and Victoria hasn’t stopped the development of ascochyta blight in some chickpea and lentil crops.
