Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Avoiding Algaecides while establishing plants

FA utilized nutrients that other plants can utilize. If FA grows dense enough, it will float up from the bottom and create a dense mat on the surface, blocking off sunlight to the pond bottom. No sunlight = no plants.

The chemicals that are used to control algae don't affect vascular plants, but I've observed burned spots on arrowhead leaves from concentrated Cutrine plus droplets. Just manage your spray droplets and try to avoid contacting the emergent plants when spraying in shallow water.

Reward isn't used for algae control....... So, it will harm the vascular plants.

I only use Cutrine Plus liquid and granules or Cutrine Ultra for an algaecide.
