TRINEXAPAC-ETHYL is the active ingredient of the plant growth regulator
MODDUS®, which was first registered in Switzerland and France in 1991 and
has since been granted registrations in many other countries. MODDUS® now
has many registrations world wide in sugarcane. Since 2001, MODDUS® has
been trialled in Australia on sugarcane with registration expected in 2007. The
trials conducted in sugarcane between 2001 and 2006 have shown that
MODDUS® is able to enhance the sugar content of the cane, making sugar
production more economically viable. Commercial cane sugar (CCS) was
increased by 0-1.8 units in the Herbert River District in 2004 and 2005. These
variable results can be attributed to crop agronomy, variety and seasonal
influences.
