I just took a look in my library for milfoil information and found a couple of things.

1. Nitrogen seems to be the limiting nutrient for watermilfoil so try to eliminate/reduce the amounts that get into your pond. This can be achieved through sound watershed management and Best Management Practices.

2. There is a biological control called a Milfoil Weevil (Euhrychiopsis lecontei). Although I have never used this product and therefore cannot actually recommend it, it is available. You can buy them as part of a management plan call MiddFoil by EnviroScience.

It seems as though the best option is to physicaly pull the plants out and dispose of them. This sounds like a lot of work.
