Abstract Algae cause a number of problems in water. They impede flow in irrigation system and cause taint and odour problems in potable waters … etc. In Egypt, one of the main canals called Suez Canal has become eutrophic as a result of the input of excessive plant nutrients from agricultural activities. Filamentous algae is the most common aquatic weeds problem in Suez canal where it is sudden appearance as it floats off the bottom produce undesirable odours and spoils the taste of drinking water. In this research, a novel method of controlling algae by using rice straw has been investigated in Suez Canal. It offers a cheap, environmentally acceptable way of controlling algae. The decomposition of rice straw in water produces and releases many compounds. Hydrogen peroxide may be considered the main substance in controlling algae. Also the analysis of water samples indicated that the chemical compound does not eliminate existing algae cells but interferes with and prevents the growth of new algae cells. As long as rotted straw was existed, no filamentous algae were recorded due to the synergistic effects of various humic substances in the rice straw. The criteria of using rice straw such as means of fixing the straw, quantity and timing of applying in such an open canal has been pointed out in order to obtain an acceptable result.
