In Kayago, Uganda, a killer weed has returned, decimating fishing grounds and clogging waterways. The weed, also known as the water hyacinth, is a beautiful lavender flowering menace, which doubles in mass every two weeks and deprives organisms living in the water of life-sustaining oxygen.
A few years ago, scientists fought the deadly weed by introducing tiny weevils called â€œsnout beetlesâ€, into the water to feed on the plant. The beetles only eat the hyacinths, so they are no danger to other aquatic plants in the area. This time, a â€œprolonged droughtâ€ will hinder this method of controlling the hyacinth.
