Growers may be inadvertently selling plants listed on the federal noxious
weed list as water garden plants. USDA stepped up monitoring and
enforcement efforts for these weeds, said Craig Regelbrugge, ANLA sr. dir. of govt. relations. "Fines can reach the thousands and hundreds of
thousands [dollars], so it's something the industry needs to pay attention to," Regelbrugge said. He urged growers to check their list of aquatic plants against the federal noxious weed list, which includes Eichhornia azurea (anchored water hyacinth); Hydrilla verticillata; Sagittaria sagittifolia (arrowhead); and Salvinia auriculata (giant salvinia).

water garden plants on federal noxious weed list
Milfoil is a noxious weed here and taking over some of the lakes and ponds. In fact, many of the state parks now have a ranger that checks the boats going in or out of the water for milfoil. Little pieces of plants can get caught oup in prop and transported from to different waterways.
Water chestnut is a big problem here........and they(the DEC )wants anyone who see's it to destroy it on site.....
