Field pea blackspot sowing guide for Western Australia - 27 May 2019

Page last updated: Tuesday, 28 May 2019 - 5:54pm

Please note: This content may be out of date and is currently under review.

Field Pea Blackspot Management Guide is a location and season specific weekly forecast. It accounts for varietal resistance and chemical options, agronomic yield potentials, agronomic constraints (frost and terminal drought), risks of spores showers, disease severity, and disease related yield loss. It then weighs agronomic yield loss and disease yield loss and suggests a window of sowing dates. Field pea crops should be sown so that the majority of blackspot spores (approximately 60%) have been released prior to the crop emergence.

This prediction is based on DPIRD’s Blackspot Manager model using weather data from 1st January 2019 to 26th  May 2019 from the nearest weather station.
