AQUATIC WEED CONTROL

Excessive growth of aquatic weeds is something most pond owners are forced to deal with sooner or later. Because most ponds are dug
in low areas they are a natural catch basin for runoff. Over time the nutrients and fertilizers that are carried in by the runoff cause
excessive weed growth. Chemical control of aquatic weeds is currently the most effective way of dealing with these problems.

Unfortunately, no single product will control all types of weeds. Instead, proper identification of weeds is necessary so the proper
product can be used. Usually one or two weeds will be the thickest is the pond and they should by treated first. If there are other types
of weeds left after treatment they can by dealt with of left if they're not too thick. Some weed cover is good for fish structure. After
identifying your weeds proper dosages and application are important. Most products need to reach a certain concentration to be
effective and under applying will provide poor results. Also, how chemicals are applied can effect the results. Treatments should not be
made after a heavy rain or any time the pond has been stirred up. Wait until the water settles before applying. Best results are obtained
by treating on a sunny morning so as the pants draw in the sunlight they also draw in the treatment.

All of the products we sell for weed treatment are safe to use with fish. Fish kills can result however if excessive product is used or from
 an oxygen depletion as a result of the dying weeds. In most cases if the chemical is going to harm the fish it will occur soon after
treatment is applied. If the fish react after a couple of days then its usually a result of oxygen loss. Treat small amounts of the pond at a
time to prevent oxygen depletion or have an aeration system running to be safe. (Usually treat 1/4 to 1/3 of the pond at one time).

The regular use of an aeration system and/or the use of pond bacteria help to decay the heavy muck layer which usually results
from years of decaying weeds, leaves, etc.

The use of safe chemicals is still the best way to keep your pond or lake from becoming infested with aquatic weeds.

Shore-Klear is a non-selective herbicide used around ponds, lakes and streams for control of cattails, brush and weeds that grow out of the water. Shore-Klear is not effective on plants that grow under (or mostly under) the water. Shore-Klear is sprayed onto the foliage of the plants and kills the plant and its roots. Shore-Klear must be used with activator (below). Application rate is two ounces per gallon of water. Some plants, like cattails, may require a second application. Effectiveness may be reduced if rain occurs within six hours of treatment. Results will begin to show in two to four days in most plants but can take as long as two weeks. Waters treated wit Shore-Klear have no restrictions for swimming, irrigation, or human or animal consumption.  Product is sold under the Shore-Klear name in quarts and AquaPro in 2.5 gallon.  The product is the same but the names are different according to container size.

CIDE KICK II and CYGNET PLUS are liquid additives for use along with liquid herbicides and algaecides to enhance their effectiveness. The surfactant in these non-ionic, water soluble and biodegradable products eliminates beading, providing a uniform spray solution. This ensures maximum contact with the plant's foliage. The low viscosity oil in these products breaks down the waxy coating on leaf surfaces for improved penetration and coverage. Use three ounces per gallon of water.

Algae is by far the most common problem for pond owners. Often pond owners try to rake or pull the algae from their ponds only to have it come back in a few days. Chemical control is the best way to control algae. Algae controls come in both liquid and granular form. Liquid products should be used when the algae is floating on the surface or in shallow water (up to 3' - 4' deep). Granular control should be used in deeper water and for bottom growing algae and chara.

CUTRINE PLUS LIQUID is a chelated copper algaecide that stays active and is safer to use than copper sulfate. Use liquid Cutrine for surface or suspended algae. Dosage rates: 0.6 to 1.2 gallons per acre. No water restrictions. Apply by sprayer to surface using one quart with two gallons of water.  For best results use activator (above) with Cutrine. 

Stocktrine is diluted algaecide for use in garden pools, stock tanks and other small bodies of water where fish are NOT present.

CUTRINE PLUS GRANULAR is the granular form of Cutrine and is recommended for bottom growing algae and chara. Dosage is 60 pounds per acre. No water restrictions.

K-TEA LIQUID is also chelated copper. This product is similar to Cutrine, but has an 8% copper base instead of 9% like Cutrine. Available only in 2.5 gallon jugs. No water restrictions. Dosage: 0.7 to 2.9 gallons per acre.

SONAR is a specialty herbicide that controls almost all aquatic weeds. Sonar should be applied early in the season, prior to or just after plant growth begins. Very effective on duckweed and milfoil.  Treatments last for several seasons in many cases.  Sonar is absorbed by the plants and inhibits the weed's ability to make food, causing it to die.  Initial results can be seen in ten days.  Complete kill can take 30 to 90 days.  Amount of treatment depends on type of plants.

WEEDTRINE-D is a broad range herbicide that controls duckweed, coontail, elodea, naiad, pondweed and milfoil.  Weedtrine-D is applied by common sprayers.  Results often begin to show in as little as three days.  Five day water restriction.  Dosage rate: Duckweed - five to seven gallons per acre, submersed weeds - five to ten gallons per acre.  Use with activator above for best results.  Weedtrine is a restricted use pesticide in Michigan.  A copy of your pesticide applicators license must be shown to us to buy Weedtrine in Michigan.

REWARD is a concentrated aquatic herbicide that's been proven on a wide variety of aquatic plants including Milfoil, Cattails, Duckweed, Pondweed and others. This liquid herbicide is applied by sprayer and should not be applied to turbid waters. There is very little risk of environmental damage since Reward's concentration rapidly decreases as it is absorbed into the aquatic vegetation. Reward is a restricted use pesticide in the state of Michigan.  A copy of your pesticide applicators license must be faxed to us before we can sell to anyone in Michigan.  All other states are not restricted and can be shipped without certification.  Application rate is one to two gallons per acre.  Should be used with activator for best results.

HYDROTHOL granular is a fast-acting, contact herbicide effective on a variety of aquatic weeds including milfoil, coontail, hydrilla, sago pondweed, leafy pondweed, curly leaf pondweed and others. Hydrothol should only be used for spot treating. Use Aquathol (below) early in the season when plants are young and easier to treat. Slight water restrictions.

AQUATHOL SUPER K
Aquathol granular herbicide utilizes Culigel® super absorbent polymer technology. Aquathol Super K is six times more concentrated than regular Aquathol. This means less product to handle, less labor to apply and reduced container disposal. Excellent for spot treatment of Hydrilla, Pondweed and Eurasian Milfoil. Dosage rate is variable according to plant species. Available in granular form in 10 lb and 25 lb containers or in 2.5 gallon liquid form.

KOMEEN is a copper herbicide for use on elodea, hydrilla and other aquatic plants (see chart below). No restrictions on water usage. Dosage rates: Eight - ten gallons per acre. Komeen must ship via motor freight as a hazardous material.

NAVIGATE is a 2, 4-D based herbicide for control of water lilies, coontail, Eurasion milfoil, parrot feather, watershield and bladder wort. Granular form makes it ideal for spot treating. Dosage rate is 100-200 lbs per acre. Slight water restrictions.  Navigate is also sold under the name Aqua-Kleen, so packaging may occasionally have the Aqua-Kleen label.

BUFFERED ALUM PHOSPHATE CONTROL

Alum is widely recognized as a great way to reduce phosphates and create crystal clear water. Alum is aluminum sulfate, when the aluminum ions bond with the phosphate molecules they become insoluble in the water, no longer available as a nutrient. The aluminum ions also attract dirt particles which, when drawn together, become heavy and settle to the bottom resulting in sparkling clear water! The pH of the water must be below 8.2 before treating with Phosclear! Application rates vary from 17-70 lbs per acre foot of water.

The following chart shows which treatments work best on each aquatic plant:
E = Excellent Control            G = Good Control

*Call for general restrictions on use of treated water
*Always refer to product label for specific requirements
