Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants diuron 80df

Mark,

Diuron is indeed not to be used by recreational pond owners. It was not originally made for pond use ,but with research was found to be very good at killing phytoplankton in ponds at very low doses. At high doses it kills most any vegetation. It has been very useful in aquaculture to control intense algae blooms but fish farms have a lot of aeration equipment to handle the fallout from killng of all that algae. Most fishing ponds do not. Low dissolved oxygen from decomposing algae = dead fish. There is a special exemption that must be applied for yearly to allow fish farmers to purchase diuron. Co-ops are not supposed to sell the stuff to anyone without an applicators permit and proof of farm ownership such as Catfish Farmers of America registration here in Alabama.
