General Weed Control: Apply 4-6L per hectare diluted in 100-200L of water
Spot Treatment: For smaller areas, mix 40ml per litre of water and apply directly to weed foliage using a knapsack sprayer
Boom Sprayer Application: Use 4-6L per hectare for larger areas, adjusting the dilution based on weed density and target area size
