    I am mowing an industrial site with a drainage pond in the front. The pond is about half the size of a football field, and is surrounded by aprox. 3 acres of lawn that is sloped toward the pond. This is my first year fertilizing, and I have never had experience with a drainage pond......and, yes, there are fish in it.( Fertilizing previously done by liqui-green). All of the pre-emergents and weed and feed have warnings about being harmful to aquatic life. Don't see any of these warnings on the regular stuff. I must use granular because I have an electric broadcast spreader that fits on the front of my ztr.........I will probably talk to my local Illinois dept of ag extension office, but was wondering if anyone has any suggestions?

    Make it a pass or 2. 4 feet isn't enough

    If I leave a buffer zone, can I use the weed and feed product with the label warnings about aquatic life????????

    If I were you I'd leave at least a 15 foot buffer zone. The steeper the slope the bigger the buffer zone. Barricade would be a good choice for pre-emergents here. Liquid weed control would be a much better choice than weed and feed. Use a fertilizer with lots of slow-release N, and little Phos.

    READ THE LABEL all pesticide labels, yes weed and feed is a pesticide, has woording pertaining to how close to a body of water you may get. Most often it states to avoid where run off will contaminate the water. So, stay far enough back to avoid normal rain or irrigation from washing the product into the pond.:)
