Good things come in small packages: plant growth regulators in barley locations
Aims

To assess the effect of PGRs and fungicides on variety-specific barley yields.

Key messages

PGR applied to barley in this trial suppressed plant height, generated a yield benefit and improved crop gross margin.

No single variety responded differently to the addition of PGR or fungicide in this trial.

Fungicide extended the green leaf duration of the crop.
