Colonises disturbed wetland sites. 316, 167, 242
Hand remove scattered plants. Spray dense infestations metsulfuron-methyl 0.1 g/15 L (2-3 g/ha) + wetting agent or
Lontrel® ® 6 mL/10 L (300 mL/ha) + wetting agent to late flowering (will prevent seed set).

Hand remove scattered plants. Spray dense infestations metsulfuron-methyl 0.1g/15 L (2-3 g/ha) + wetting agent. 258, 101, 222, 167, 242
Hand remove isolated plants. Chemical control only effective at early growth stages. M. australiana 197, 222, 167, 242,
25 mL of wetting agent + 10 mL of Lontrel® ® in 10 L of water provides effective control in early winteror
metsulfuron methyl 0.1 g/10 L + wetting agent.

Weed of highly disturbed bushland. If slashing cut below lowest branch axil to prevent resprouting. 300, 335, 167, 242
Hand remove isolated plants through spring and early summer. Spot spray with 0.5 % glyphosate or Lontrel® ® 10 mL/ 10 L
(500 mL/ha).
334, 316, 167, 242, 222
Spot spray with glyphosate 0.5 % before flowering. 222, 167, 242, 222
Spot spray with glyphosate 0.5 % before flowering. 167, 242, 222
Hand remove before flowering. Will shoot from stem fragments under moist conditions. Spot spray 0.5 % glyphosate. 217, 167, 242, 222
Weed of highly disturbed edges. Hand remove isolated plants several times over the year. Spot spray 1% glyphosate before
flowering.
Only persists in disturbed sites. Lontrel® ® at 10 mL in 10 L of water + 25 mL wetting agent applied before stem elongation in
late spring.

Weed of disturbed sites. Shade reduces seed production. Hand weed small infestations. 300, 167, 242

Slashing often ineffective as flowers continue to be produced. Rosette stage preferred time for effective chemical control.
Lontrel® ® at 10 mL in 10 L of water + 25 mL wetting agent.

S.hydrophilus
Native
Sowthistle
Colonises disturbed wetlands. Hand remove isolated plants before seed set. 167, 242
Glyphosate 1 % effective on seedlings. Exclude people and close tracks to stop spread. On bare tracks diesel can be used to kill
plants and penetrate and destroy seed in surface soil.
Hand remove isolated plants before flowering. Spot spraying Lontrel® ® 10 mL/10 L + wetting agent in early winter before
flowering provides effective control.
Colonises bare disturbed sites. Can smother native plants. Lontrel® ® 10 mL/10 L + wetting agent provides effective control in
early growth stages or metsulfuron methyl 0.1 g/ 10 L + wetting agent.
