(i) Physical removal of weeds: It involves cutting, pulling, or raking weeds by hand. It is time-consuming and labor-intensive and is most suitable for small areas or for locations that cannot be reached by machinery.

(ii) Mechanical removal: It is accomplished by specialized harvesting machinery equipped with toothed blades and cutting bars to cut the vegetation, collect it, and haul it away. It is suitable for off-shore weed removal or to supplement chemical control.

(iii) Biological control: These methods generally involve the introduction of weed-eating fish, insects, competing plant species or weed pathogens into an area of high weed growth. While there are individual success stories (for example, stocking lakes with grass carp).
