Annual weeds in sugarcane fields compete with the crop for water, nutrients, and light, and severely infested fields show significant yield reductions. Herbicide selection for weed control must be based on the target annual weed species and its precise growth stage—Hexazinone·Diuron 60% WP 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.
Hexazinone·Diuron 60% Hexazinone·Diuron Wettable Powder, Registration No. PD20110574 (subject to the actual label). Used for control of annual weeds in sugarcane fields at 145–185 g/mu, directed spray. Dilute with water according to 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 on windy days or before rain. Dosage varies considerably among different formulations—conduct a small-scale trial first before large-scale application. Always follow the label instructions.
