MODDUS® (active ingredient Trinexapac ethyl) is registered for use as a crop
growth regulator or crop ripener in numerous South American sugarcane
growing regions. Between 2003 and 2005, field trials were undertaken to assess
the chemical's potential as a crop ripener for the Australian sugar industry. The
results indicated that the chemical has significant potential as a crop ripener to
increase commercial cane sugar (CCS) at particular times during the normal
harvesting period available for the Australian sugar industry. The product is
currently not registered in Australia. However, a permit was granted by the
APVMA in early 2006 to undertake the pilot program and to conduct further
research. It is hoped that the product will be fully registered for use in the
Australian sugar industry soon. It was decided to establish a pilot program in
2006 to assess the commercial opportunities that such a product could deliver to
an Australian sugarcane growing region. With support from Syngenta Crop
Protection Pty. Ltd., CANEGROWERS-Herbert River, BSES Limited, Herbert
Cane Productivity Services Limited (HCPSL), CSR Sugar, Queensland
Mechanical Cane Harvesters Association (QMCHA) and SRDC, the 2006
Herbert MODDUS® Pilot Program was established.
