LAKE MANAGEMENT SUPPLIES

    The use of aquatic chemicals to control unwanted plant growth in ponds, lakes and ditches has increased rapidly as more demands are made on these resources. This has also caused much confusion regarding what chemicals may be safely used in water. The proper choice of chemical or nuisance vegetation control is extremely important. There are basically two groups of aquatic vegetation: Algae and Vascular plants. Within these groups there are several general types.

ALGAE: Plants without true leaves and stems, many are microscopic.

• Chara and Nitella - specialized algae which grows attached to the bottom soil, extends into the water column and very closely resembles several vascular plants.

• Filamentous Algae - probably the most common aquatic nuisance plant. Growth is highly variable ranging from very slick and slimy to coarse horsehair texture.

• Planktonic Algae - single plants are mostly microscopic in size; However, due to high numbers present, they give the water a color (brown or green) and in very nutrient rich waters often "bloom" producing excessive growth and soupy green water. The blue-green algae group produces strong odors and some species also release toxins which have resulted in illness and death to livestock.

VASCULAR PLANTS: Plants having stems and leaves.

• Emergent - plants growing in or near the water with a large portion of the plant exposed above the water level such as cattails, rushes, spatterdock and water willows.

• Submersed - plants growing attached to the bottom soil and growing within the water column, often completely to the surface, such as elodea, curly leaf pondweed, naiads, coontail and milfoil.

• Floating - plants which are either free floating, such as duckweed and watermeal or plants which are rooted in the bottom and produce leaves which float on the surface, such as water lilies.

    Within these general categories, there are many distinct kinds, or species of plants. Experience has shown that many factors affect the results of treatment programs including chemical choice, dosage rate, application method, timing, weather conditions, extent of coverage, water movement, etc. Some factors are beyond your control but must be considered in planning.

1. Use of water - check this against precaution statements for the chemical.

2. Proper identification of nuisance vegetation - (Guessing, can be costly!)  Having trouble identifying your plants, just give us a call or drop by with a sample of the plant(s) and we will help to properly identify them.

3. Proper dosage of chemical - varies with plant type and species. Rates are generally given by surface acre (43,560 sq. ft.) or acre foot (surface acres X average depth of water).

4. Time of application - most aquatic herbicides can be used effectively any time throughout the growing season with proper adjustments and precautions. Early season treatments when plants are actively growing, are generally most effective and efficient. Water temperature should be 50 F or higher.

    AQUA SPRINGS stocks only registered aquatic chemicals and the popular non-toxic vegetation control alternatives. Items are presented in several categories with a brief explanation of uses and precautions for chemicals, to help you choose the correct materials and equipment. If you need assistance, we provide identification and program recommendations for aquatic vegetation.
