New fungicides offer improved ascochyta blight control and yield benefit in field pea locations
Aims

To evaluate the efficacy of new actives in disease control and yield benefits in low (Minnipa, upper Eyre Peninsula) and medium (Hart, Mid-North) rainfall zones in South Australia

Key messages
  • Early disease control is important for reducing initial AB infection levels in field pea crops with a yield potential above 1.5 t/ha.
  • A late fungicide spray is important to control AB in spring when rainfall is conducive to disease spread and pod and seed infection.
  • Early sowing into a high disease risk window with new fungicide actives evaluated in this project, were demonstrated to have improved yield benefits over later sowing in the 2017 season.

Acknowledgments

Funding for this work was provided through GRDC project DAV00150 (Southern Pulse Agronomy) and their support is greatly appreciated. We also acknowledge the support of research colleagues from the SARDI teams at Clare and Minnipa. Much gratitude also goes to the land owners/managers of the different farms where the trial sites were located, and to chemical companies for providing us with experimental fungicides to run our trials.
