Pesticide Management

The final report on its performance is not due until the end of June but the rainfall simulation results have been very encouraging, not just for imidacloprid, but also for nutrients - so much so that Bayer and Incitec are undertaking further trials across districts (which you may already be aware of):  
  • Imidacloprid run-off loads over the three rainfall simulation events were about 18.1 g/ha for the closed wheel, compared to 52.4 g/ha for non-closing wheel application.
  • The open application drill would also have resulted in some Imidacloprid loss through solar radiation breakdown so the reduction in Imidacloprid run-off associated with the closed wheel is a significant development.
  • Nitrogen run-off loads over the three rainfall simulation events were about 18.3 kg/ha for the closed wheel, compared to 32.15 kg/ha for non-closing wheel application.
  • Phosphorous run-off loads over the three rainfall simulation events were about 1.2 kg/ha for the closed wheel, compared to 2.0 kg/ha for non-closing wheel application.
