What herbicide is good for weed control in chive fields
1. Pre-emergence
48% dinitramine, 3 to 3.75 liters per hectare applied after sowing and before emergence in seedling beds.
50% prometryn WP at 1.5 grams per hectare, applied after sowing and before emergence in chive seedling beds; 50% prometryn WP at 1.5 to 2.25 grams per hectare, applied to old chive fields after cutting once the wounds have healed and new leaves have grown.

2. Post-emergence
