Source? likely to be reintroduced: 

P. dilatatum has a medium to high risk of introduction into tropical, subtropical and temperate zones, usually to be used as forage/fodder. However, its low sexual reproduction, low germination and slow establishment, together with its susceptibility of being infected by ergot (Claviceps paspali), are a deterrent to its spread. Nevertheless, the use of this species is favoured due to the high productivity of livestock that feeds on it

Info Blurb: 

Its dense growth habit tends to smother and prevent other native species from flourishing. Rapid growth and profuse seed production enable it to quickly invade agricultural land, especially rice fields, waterway margins, and managed urban sites. Creates an unsightly clump in turfgrass that can be a problem in golf courses, sports playing fields, and home landscapes. Introduced as a forage crop.
