Field pea blackspot management guide for South Australia - 17 June 2024

Page last updated: Tuesday, 18 June 2024 - 8:46am

Field Pea Blackspot Management Guide is a location and season specific weekly forecast. It accounts for risks of spore showers, disease severity, and disease related yield loss suggesting a window of sowing dates that minimise risk of blackspot disease.

This prediction is based on DPIRD's Blackspot Manager model using weather data from 1st January 2024 to 16th June 2024 from the nearest weather station.

You may notice weather station changes for some locations. This is to ensure that the weather data being used is the most accurate available for the area and uses open BOM weather stations whenever possible. In some locations, a suitable weather station may not be available and so we may use interpolated weather data, which uses data from surrounding stations to create reasonable values for missing weather data.

Sowing time can depend on a range of factors and it is recommended to consult an agronomist to determine the optimal sowing window for your situation. For more information on blackspot in South Australia contact Sara Blake at SARDI on (08) 8429 2248 or email sara.blake@sa.gov.au

Key to blackspot severity scores

The aim is to delay sowing of field pea crops, where agronomically possible, until the majority of blackspot spores (approximately 60%) have been released prior to the crop emergence. This strategy reduces yield losses from blackspot.
