Key Points
- Generic Trinexapac-ethyl formulations resulted in similar seed yields to the industry standard (Moddus) at all three rates.
- There was no difference in seed yield response in either a turf or a forage diploid ryegrass cultivar.
- In the turf cultivar one of the TE formulations was less effective in delaying lodging as assessed by days to 50%lodging in relation to others. However this did not translate into a difference in seed yield. In the Forage cultivar no differences were observed.
- All products were of similar price per litre with the Margin Over Chemical Cost (MOCC) favouring the higher yielding treatments, regardless of input cost.
