Aims

To monitor for 3 key pests in maize crops - Heliothis, Fall Armyworm & Two Spotted Mites, then apply treatments that are IPM friendly if needed (Bugs for Bugs and IPM friendly insecticides).  The demonstration block will be compared to the farmers conventional treatments on the crop.

Key messages
  • Drone application of beneficial insects and ViVUS® Max was demonstrated as an alternative to using a plane or helicopter.
  • ViVUS® Max could be considered to be a viable option for the control of heliothis.  If it was also applied via overhead irrigation 2-3 applications of ViVUS® Max could be done for the same cost as a single application of Zeal. 
  • At sites with a low Two Spotted Mite pressure (Coleambally and Tocumwal) the beneficial insects did control the mites at an equivalent level to Zeal or Abamectin.
  • At the high Two Spotted Mite pressure site (Cooma), the trial had to be terminated as the beneficial insects were not able to adequately control the mites.
  • No difference in yield was found between the conventional and IPM blocks at Tocumwal and Coleambally.
Tocumwal 2022

Heliothis & FAW numbers were monitored and recorded on a regular basis.  In the FAW trap numbers remained very low or zero.  The Heliothis trap numbers did increase during the season, which resulted in the crop requiring treatment.

The crops were inspected for mites

Coleambally NSW 2022

Heliothis & FAW numbers were monitored and recorded on a regular basis.  In the FAW trap numbers remained very low or zero.  The Heliothis trap numbers did increase during the season, which resulted in the crop requiring treatment.

The crops were inspected for mites from 3 weeks before tasselling.  The crops did receive a miticide application around this time
