John A Roncoroni Title: Weed Science Farm Advisor Specialty: Weed Control and Vegetation Management in Perennial Crops, Covercrops and Aquatic Weed Control Address: UC Cooperative Extension Soscol Avenue Suite 4 Napa, CA Phone: () Email: [email protected] Proper identification of aquatic plants is essential if chemical control options are utilized. Chemical control options will vary for many of these aquatic plant species (Table 1). This publication does not attempt to identify all aquatic plants that may be present, but only to identify those most common. Aquatic plants can be broadly.

Chara is best identified by its musky odor and gritty textures as a result of surface calcium deposits. Dense growths attach, but do not root, and may cover the entire lake bottom. Treatment Options: Cutrine-Plus® G.

  The nonclassical biocontrol method incorporates mass rearing and the periodic release of naturalized nonnative aquatic weed biocontrol agents to increase the effectiveness of control. An example of this method is the enhanced rearing and release of Chinese grass carp (Ctenopharyngodon idella Valenciennes) for reduction of nuisance aquatic Cited by: 2. The operations and maintenance project for the removal of water hyacinth and alligator weed in Louisiana has been in existence for many years, and the application of 2,4-dichlorophenoxy-acetic acid (2,4-D) has evolved as the most effective means of : Edward O.

The systems will become choked with weeds and become useless unless weed control is practiced. influencing the aquatic environment and the resultant vegetation.

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.
