In 2014, ICC applied plant growth regulators (PGRs) on barley, canola, faba bean and wheat trials to see if stubble load could be influenced. Plant Growth Regulator is a term that describes many agricultural and horticultural chemicals that influence plant growth and development. Most of the broadacre use of PGRs is to have a negative influence on plant growth; they are applied with the intention of producing a smaller plant that is resistant to lodging or reduce excessive growth in the crop.
NOTE: Not all products used in these trials are registered for use on all crop types, and some products are registered for use but not as PGRs which may have different rates and
timings from that on the label. The products were used for experimental purposes only. Label regulations should be adhered to when applying to commercial crops.
The stubble project – maintaining profitable farming systems in Victoria and Tasmania with retained stubble (project number BWD00024) is funded by the GRDC.
