Wetting agent and/or summer spraying oil may be beneficial

Cotton bush can be sprayed at any time when actively growing: September-December is the most effective time to spray before fruit forms.

• Glyphosate is effective on mature bushes, regrowth and seedlings, provided good coverage is achieved.
• Where low volume/low pressure pumps are being used the rates should doubled.
• Slash established bushes during winter, and burn, cultivate or grub seedlings and regrowth.
• Roundup Biactive® or Razor® preferred treatment in wet areas or along water courses near shallow water.
• The addition of 1g of metsulfuron/100L of water has also given improved control.

600g/L triclopyr. A 755g/L formulation also available.       

30mL

Use crop-oil such as Uptake® @ 500 mL 100 L, or DC-Trate @ 1L/100L

Spring-December

• Use in place of glyphosate when annual pastures are still growing to avoid damage to grasses.
• Other products containing triclopyr and picloram are also reasonably effective but further work is required.
• Dicamba is effective on seedlings.
