Weed Control Option Tables 37NORTHERN TERRITORY WEED MANAGEMENT HANDBOOK 2012 Chemical and concentration Rate Weed growth stage, method and comments 2, 4-D amine 625 g/L Various trade names 320 mL / 100 L or 1.1 - 2.4 L / ha Seedling or adult (individuals or infestation): Foliar spray apply when actively growing Foliar spray use lower rate on seedlings Glyphosate 360 g/L Various trade names and formulations 15 mL / 1 L Seedling or adult (individuals or infestation): Foliar spray apply when actively growing Non-chemical applications: Improved perennial or native pastures will prevent establishment. Avoid heavy grazing as it will encourage growth. Slashing shortly before fl owering can also effectively prevent seed production but not too early as plants can re-sprout and produce new fl ower heads.

Slashing should always be done prior to seed set, preferably when plants are fl owering. Rotary hoeing or discing infested areas and immediately sowing with improved pastures can be effective, if the grasses are well managed. Avoid grazing paddocks containing sicklepod or senna, especially when mature seed is present. A constant, dense sward of grass will exclude sunlight and help to maintain soil moisture.
