VI Aquatic Weed Management Control Methods. The canal weed control is a complex task demanding knowledge of aquatic plants. Mechanical control is expensive and requires access to waterways, while chemical control is easier, quick and usually cheaper when compared to mechanical methods [5], but herbicides are often toxic that the water cannot be used often for fish culture or human, fere with people’s activities either by their over-abun-dance or by their mere presence. When this occurs the plants are considered “weeds” and some control is desired. Different problems occur in different types of waters. The main water types and their associated aquatic plant problems are as follows:.

The introduction of bio-agents will become one of the major methods of controlling aquatic weeds, especially the floating ones. Researchers are envisaging to establish an integrated approach to aquatic weed control using a mix of mechanical and biocidal techniques to control aquatic weeds under specific situations (ICID).
