June–October (best results when flowering)

• agitate well to ensure good mixing when using small quantities of chlorsulfuron — dissolve before adding to the tank: the spot spraying dilution is based on 20g/ha
• to avoid the need to measure very small quantities of chemical add 1g chlorsulfuron to 1L of water: use 200mL of this mix to 10L of water in a knapsack sprayer
• glyphosate can be used at 1:100 but results are only fair.
