DeWort (Biocontrol solution for aquatic weeds)

Cleanup of Peerjadi Guda Lake in Hyderabad filled with Water Hyacinth:

The lake is spread in an area of 36.5 Acres. The lake was covered with water hyacinth and weeds. The growth of weeds was due to the sewage emerging in the lake from the surrounding colonies. The application of enzymes was done using a boat and high-power spraying equipment. The enzymes were spread across the lake by complete drenching the weeds. Within first day the weed started to wilt and killing effect started on day one itself. By the end of first week, the whole application was completed. Buy 10th day most of the weed was dead and another spray of organic matter digesting enzyme was applied to digest the dead weeds biomass. This application was to prevent the formation of sludge at the bottom and decaying of the water hyacinth plant material to avoid foul odors from the lake. The complete digestion of the weed was completed by the end of second week. Within a month the lake was clear of the weeds and clean. The effect lasts for a year and fresh weed growth occurs only if there is an incoming sewage from other lakes.
