Algae & Aquatic Weed Management

AC&T personnel can assess aquatic systems in terms of aquatic vegetation and water quality conditions to identify appropriate vegetation control measures. These measures may include an integrated plan composed of physical removal or exclusion, introduction of biological predators, and use of EPA-registered aquatic herbicides or other water treatment chemicals. AC&T and their personnel are licensed by Arizona Structural Pest Control Commission to provide recommendations and to make aquatic chemical applications

Physical Methods: AC&T personnel can evaluate lake conditions to determine if physical removal of plant material is possible. Removal can include filtration or sedimentation of algae, or cutting and harvesting of submerged or emergent weeds.

Biological Methods: For some aquatic plants, herbivorous fish are an economically sound method of density management. Herbivorous fish can often provide years of submerged weed control. AC&T works with the client to identify the current level of weed infestation and determines the proper stocking density based on level of control required. AC&T can also arrange for all stocking permits and delivery of fish at competitive prices through their supplier.

Chemical: When use of physical or biological management options are not conducive to the situation, chemical alternatives exist for management of all types algae and aquatic weeds. After identifying the species of concern, AC&T personnel will identify the chemicals or aquatic herbicides that can manage the growth. The chemicals may include flocculants such as alum or polymers, light-reducing water-soluble dyes, algaecides containing copper, endothall, or peroxide, and any of a variety of aquatic (weed) herbicides. Product options, dosages, frequency of application, potential hazards to non-target organisms, and total material costs and labor charges are always provided to the client for their review and input into selection.
