I\u00a0respond to\u00a0all sorts of pond weed\u00a0calls each week. Several of these calls have been the result of an unusual looking weed called Waterfern (Salvinia minima<\/em>).\u00a0Not to be confused with its\u00a0larger cousin, Giant Salvinia (Salvinia molesta<\/em>), who is actually on the federal noxious weed list.<\/p>\n

Waterfern is a floating fern that is native to South America. It was probably introduced into the US through the trading of ornamental plants for fish tanks. It grows well in our area and can easily cover the surface of small and medium sized ponds with a dense floating mat\u00a0if not controlled.<\/p>\n

Herbicides are the most effective control once the weed is established. Be sure not to treat\u00a0more that 30-40% of the pond area at any one time as decaying plant material will deplete dissolved oxygen and result in fish kills, especially in the warmer months. Only two herbicide active ingredients are particularly effective in controlling this weed:<\/p>\n

1) diquat (Reward, many generics)<\/p>\n

2) flumioxazin (sold for aquatic use as Clipper)<\/p>\n

Both products will require the addition of an aquatic approved spreader\/sticker to work properly. Diquat provides\u00a0descent control of many aquatic weed species. Flumioxazin provides great control of a few common pond weeds. Herbicide choice would depend on other weed species present and size of\u00a0the area to be treated since flumioxazin is very expensive. Call me for recommendations\u00a0that fit\u00a0your specific situation.<\/p>\n","protected":false},"excerpt":{"rendered":"
