Annual weeds in sugarcane fields compete with the crop for water, nutrients, and light, and severe weed infestations can lead to significant yield losses. Herbicide selection for weed control should be based on the target annual weed species and their precise growth stage. Diuron 60% + Hexazinone 60% Water Dispersible Granules (Diuron·Hexazinone 60% WDG) is registered for the control of annual weeds in sugarcane fields.
For annual weeds in sugarcane fields, different herbicides are required for grasses versus broadleaf weeds, and the application methods also differ between pre-emergence and post-emergence treatments. For soil residual (pre-emergence) control, herbicides should be applied after sowing but before crop emergence, forming a herbicide film over the soil surface. For post-emergence foliar treatments, spray directionally when weeds are at the 3–5 leaf stage and when the crop is relatively safe.
Diuron-Hexazinone 60% Diuron-Hexazinone Water Dispersible Granules, Registration No. PD20132091 (subject to the actual label). Used for the control of annual weeds in sugarcane fields at a rate of 140–180 g/mu, applied as directed foliar spray. Dilute with water according to the weed spectrum and crop growth stage, and spray evenly. Take care to avoid spray drift onto the crop.
For stem and leaf herbicide application, lower the nozzle and spray only the weeds to prevent spray drift from reaching the crop and causing injury; do not spray during windy conditions or before rainfall. Dosage varies considerably among different formulations—conduct small-scale trials first before large-scale application. Always follow the label instructions.
