PONDWEED DEFENSE
Pondweed Defense is safe, rapid-acting contact herbicide designed for many species of aquatic vegetation. Best with
mature aquatic weeds. Treated weeds generally drop below surface in little as 4-7 days. In heavily infested areas 2nd
application may be necessary in 10-12 weeks. Use in combination w/ Algae Defense for faster results and algae control.
DO NOT USE IN PONDS
WITH KOI & TROUT
DUCKWEED
Leaves size of pencil eraser. Individually
or in clusters. Small root hairs may
be seen hanging from underside. No
distinguishable stem. Heavy growth
will blanket surface. Duckweed isn’t
interconnected as is filamentous algae.
Do not confuse with algae.
Description
ALGAE DEFENSE
ALGAE
Filamentous algae has thread like appearance. Often referred to as pond scum or moss. Forms
surface mats. Growth begins at bottom, rises to surface as bubble filled mass. May also form fur-like
growths on logs and rocks at the bottom. Planktonic algae is visible as greenish tinge, suspended in
the upper few feet of water. Commonly referred to as “pea soup”, may actually thicken water during
severe blooms.
CHARA
Leaf-like structures whorled around a hollow stem. Dense growth attached, but not rooted to the bottom.
May “carpet” large areas of the pond’s bottom. Strong musky odor when crushed. May have a
gritty texture due to mineral deposits. Do not confuse with other pond weeds.
Algae Defense works on a broad spectrum of algae. Apply in spring when water temps reach 60ºF +.
Early applications will reduce amount of Algae Defense needed and reduce amount of excess nutri-
ents caused by dead algae. Multiple applications may be needed for full season of control.

DO NOT USE IN PONDS WITH KOI & TROUT
When chemicals are used correctly, they can be effective in controlling algae and weed growth - but it is a temporary fix.
If nutrients remain in pond, problems will likely reoccur. For the best long-term results, add AERATION & BACTERIA.

CURLY LEAF
Leaves thin and wavy and finely serrated
at the edges. Stems branched.
Upper leaves are often crispy and
appear waxy. Leaves alternately on
stem. Flowers born on spikes rise
above the water surface.
EURASIAN WATERMILFOIL
Leaves in whorls of 4 w/ as many as 20
pairs of leaf divisions. Reddish flower
may be on water’s surface. Plants
reach lengths of 10’ or more. Exotic
plant, rapidly becoming an aquatic
nuisance in N. America. Spreads
quickly/grows by fragmentation.
HYDRILLA/ELODEA
These two weeds are very similar.
Both leaves are whorled in groups.
Whorls of leaves are compact near
growing tips. Spacing between whorls
increases further down the stem.
Hydrilla leaves have a serrated edge.
AMERICAN PONDWEED
The floating leaves are oval. Submerged
leaves are not abundant and
are blade-like. Fruits are on spikes
that often stand above the water’s
surface and are brownish to reddish
3 to 21 inches long and 1/8 to 1/4
inches wide.

NAIAD
Leaves are wider at the base and
arranged oppositely or in whorls of
three on the plant stem. Often grows
in thick clumps or beds. Good coverage
and dispersion of chemical is
required to achieve control.
COONTAIL
Leaves whorled around the stem
and have a serrated appearance.
Spacing between leaf whorls is variable.
Consequently, the end of the
stem leaves and whorls are crowded.
Branches are forked repeatedly. Do
not confuse with Chara.
