Removal method:

1. Combined with agricultural measures, make great efforts to dig out the roots in the soil when ploughing and stubble changing, and then be sure to dry or burn them; Manual removal and eradication shall be carried out in the invaded areas with small population density or newly discovered. The newly invaded Alternanthera philoxeroides can be eradicated by digging 1m deep and burning it thoroughly for three consecutive years.

Alternanthera philoxeroides (2 pieces) are salvaged manually in many waters, but the salvaged plants will die and revive if they are not treated effectively in time.

2. Chemical control: In China, chemical control is one of the main measures to control Alternanthera philoxeroides. Herbicides such as chlorflupiroxicam (chlorfluazuron, water peanut net), glyphosate or dimethyl tetrachloromethane are widely used in China.
