Minimise use of residual herbicide whilst maintaining adequate weed control
The project seeks to demonstrate that strategic use of knockdown herbicides can provide effective weed control in ratoon sugarcane and replace the reliance on residual herbicide.
The use of knockdown herbicides is based on assessing weed pressure in fields, weed species present, competitive risk against the crop, impact on harvesting and sprayer application equipment available.
Replacing residual PSII herbicides with knockdown products will lead to reductions in these PSII herbicides leaving farms in runoff water. PSII herbicides also have limitations in regard to their application window while knockdown herbicides are more flexible.
