Combining Cycocel with Moddus to reduce lodging risk in winter wheat locations
Aims

To evaluate the individual and combined effects of two growth regulators, Cycocel (Chlormequat) and Moddus (Trinexapac-ethyl) on lodging, yield and yield parameters. Nitrogen and gibberellic acid treatments were also included to investigate their impacts on lodging. 

Key messages
  • The greatest height reduction was achieved by the Cycocel and Moddus in combination which included an application at the start of stem elongation (GS 30).
  • Reduced height was correlated wtih an increase in lodging resistance and was achived without penalty; there was a minor trend for yield increases with PGR treatments.
  • Cycocel was associated with a minor reduction in screening >3.2mm.
