Speed of crop desiccation is dependent on crop stage, growing conditions
and weather conditions during and after application.
For application to standing crops a minimum water rate of 80 L/ha is
recommended to ensure adequate coverage of target weeds below the crop
canopy.
Any subsequent weed management strategies should involve an integrated
weed management (IWM) approach to minimize development of glyphosate
resistance.
SORGHUM Sorghum, grain sorghum 1.15-2.3L/ha DO NOT apply if crop is under stress from low moisture, frost, cold or
CONTROL waterlogging.
Pre-harvest RATE SELECTION Use the lower rate for control of crop and late tillers and
suppression of ratoon regrowth. Use the higher rate for improved
suppression of ratoon regrowth, where the crop has produced significant
number of late tillers or where following crops will be established without
further treatment.
TIMING Apply when grain moisture is less than 25%. Application can be
made when moderate browning has occurred.
CAUTION Treatment may increase potential for CROP LODGING,
particularly if prior moisture stress has occurred. Under any set of
environmental conditions, individual varieties can vary in response to
preharvest treatments. In general, varieties with a more “determinant” growth
habit are more susceptible than “indeterminant” varieties. Harvest should
commence at least 7 days after application provided sufficient dry down has
occurred to avoid possible lodging. Speed of dry down is dependent on
physiological maturity, soil moisture and climatic conditions.
CAUTION Sorghum may be naturally toxic to stock.
