Physical method means digging out roots and pieces of plant out of the soil and best time of doing this is before the purple loosestrife starts barring seeds. Once they are removed they should be burned so that they cannot reproduce as well as spread more. It can also be done by hand pulling.

If it is in dry place then by using an approved herbicides it can be killed. But it is recommended to hand spray it individually as  broadcast spraying can cause lot of damage to other plants.

Biological method is the most effective as well as time consuming method. It is basically leaving predators of purple loosestrife on it. In North America two species of beetle and one specie of weevil is used to stop the spread of purple loosestrife. Even the beetles and weevil are non native to Canada but they are environmentally safe to North America. 

Basically what this species do is that they feed on purple loosestrife controlling their population.
