Trial location(s) Inverleigh, VIC
Water use efficiency growth regulator trial locations
Aims

To examine the effect of plant growth regulators, in the form of Moddus and Chlormequat on the plant biomass, water use and plant growth in wheat.
 

Key messages
  • A mixture of Moddus and Cycocel at GS 24 will reduce wheat plant height more reliably compared to the other treatments applied on their own.
  • Plants sown into situations of higher fertility will produce taller plants that may respond better to the use of PGRs to control plant height and biomass which may improve WUE.
  • For season long plant growth regulation a follow up PGR may well be required later in the season to stop plant 'bounce back'.
