Keep density of crop high in order to shade out the weed (it grows poorly in low light):

Plant crop before weed germinates in late summer

As seeds can travel on animals and machinery, do not allow animals into an affected area, limit machinery use in the area and keep machinery clean to prevent spread

Annual or perennial creeping herb; produces seed above and below ground.

Leaves: oval to lanceolate; short hairs when young; 3-7 cm long, 1-2.5 cm wide (length up to twice width only)

Flowers: three lilac blue petals; 3-4 mm long - lower is smaller than other two and sometimes white

Fruit: pear-shaped capsule; five seeds (sometimes appear sugar-coated; grey-brown)

Stems: short hairs when young

Distinguished from other species in its genus by: all three petals blue; leaves broadly elliptical (length up to twice width only); rough, ribbed seeds; presence of stolons; leaf sheaths with reddish-brown tipped hairs

Keep a close eye on row cropping systems such as peanuts, soybeans and corn - these types of crops are favoured by the weed

Prefers wet soils but can survive for long periods without moisture. Particularly likes disturbed land.

Take action as soon as weed is seen

Uproot by hoeing or hand-pulling. When removed, shake off soil, spread out and dry for more than a week

Cut stems can resprout. Stem fragements must dessicate to a moisture content of 50% for a period of 30 days to prevent resprouting

Moldboard plough more than 1 inch below surface

Use conventional tillage as supposed to strip tillage (do not use minimum tillage systems)

Note: emphasis should be given on preventive and mechanical measures as extreme tolerance to glyphosate has been documented.
