Lake Weeds
Submersed
Emersed
Floating
Algae
1. Classify The Weed
Submersed: Growing in deeper water entirely below the
surface.
Emersed: Growing in shallow water with leaves or stems
above the water.
Floating: Growing unattached or rooted with floating
leaves.
Algae: Cellular, lower weed form. No distinguishable stem
or leaf. Moss or scum.
2. Determine Specific Weed(s)
The previous links picture common aquatic weeds found
throughout the country. Place your weed in a clear glass jar
with water and compare it to the pictures. Pay careful
attention to the leaves.
3. Select Your Product(s)
What Controls What provides a table showing what product
controls what weed(s). Read the product information to
confirm that the product will meet your needs.
4. Quantity To Order
Estimate the area or volume to be treated. This can be
done by pacing the dock or pier and shoreline, measuring
from a land survey, or by other means. For help

6. Send Us Samples
Pull a sample of each weed (be sure to include leaf and
stem), rinse with clear water and shake out. Place the
sample in a plastic bag with a brief note and your contact
information. Send to: Aquacide Company, 1627 9th St.,
White Bear Lake, MN 55110. Please do not send samples
packed in water. They rot, smell and are difficult to identify.
Do not fully dry the sample. It may turn to dust and
become difficult to identify. Please allow 10 working days
for a response. E­mail a close up photograph of your weed
to Weeds@KillLakeWeeds.com. Positive weed
identification usually cannot be made from verbal
descriptions.
