What happens if you apply less than the recommended rate of herbicide?
Applying less than the recommended rate usually results in poor weed control. Some herbicides, such as those for control of emergent plants, are applied on the basis of the area to be treated. Others, such as those used to control certain submerged weeds, are applied on the basis of the volume of water to be treated.
What is diquat spray?
Diquat is a contact herbicide that can be sprayed on or injected into water to control submerged weeds and filamentous algae; or, it can be sprayed on duckweed (Lemna minor and Spirodela polyrhiza) or emergent vegetation. Repeated applications on surface mats of algae (e.g., Pithophora) may be necessary. An approved non-ionic surfactant is required when diquat is used as a foliar application. Diquat binds tightly to clay particles and is not effective in muddy water or on mudcoated weeds. Diquat quickly kills plants and should be used as a partial pond treatment for dense vegetation.
How to control weeds in a fish pond?
Managers can quickly and economically control problem weeds in commercial fish ponds with aquatic herbicides. However, herbicides are just one method of managing aquatic weeds. There are also: 1) preventive methods such as proper pond site selection and construction, fertilization, and periodic draw-downs; 2) biological methods such as grass carp (Ctenopharyngodon idella); and 3) mechanical methods such as cutting, seining, and raking. Using a combination of methods, within a comprehensive plan, is the most cost effective and environmentally safe way to manage aquatic weeds. SRAC-360, Aquatic Weed Management – Control Methods, contains additional information on the various methods used to control undesirable weeds in fish ponds. Once undesirable weeds are eliminated, applying fertilizer periodically will stimulate planktonic algal blooms that suppress the growth of submerged weeds.
How to determine the amount of herbicide needed for a surface acre treatment?
The amount of herbicide needed for a surface acre treatment is determined by the following formula:#N#F = A x R#N#F = Amount of formulated herbicide product.#N#A = Area of the water surface in acres#N#R = Recommended rate of product per surface acre
What happens to the dissolved oxygen in the water after weeds are killed?
However, after aquatic weeds are killed the decomposition process consumes oxygen and can reduce the amount of dissolved oxygen in the water. If large quantities of aquatic weeds are killed, their decomposition can reduce the dissolved oxygen concentration to such a low level that fish die.
When to apply herbicide?
Application Timing. The best time to apply a herbicide is in the spring when water temperature is between 70 and 80F. At this time of the year, weeds are small and easier to control than during the summer, and levels of dissolved oxygen in the water are usually higher.
How to get rid of Pond Weeds Safely

Pond Weed Control for Emergent Weeds
Emergent weeds like cattail, bulrush, phragmites, purple loosestrife, alligator weed, some iris, and sedges are challenging to control because of their extensive root systems. Since the plants have so many roots, physical removal alone is not an effective treatment. However, they are readily controlled with basic aquatic herbicides.

How do pre-emergent herbicides work?
When using a pre-emergent herbicide in the soil around bodies of water, the chemicals can escape into the water through a process known as leaching. Furthermore, post-emergent herbicides can also run-off the weeds and easily flow into the body of water.
How does weed herbicide work?
The natural substance acts by interfering with the ability of a weed to process amino acids from photosynthesis. This is similar to how imazapyr interferes with the production of amino acids when applied to weeds. Natural herbicides do not directly cause toxicity in surrounding animal life near bodies of water.
What is the most heavily used herbicide?
Glyphosate. This chemical is by far the most heavily-utilized in synthetic herbicides. Glyphosate not only kills weeds, but it also kills a wide range of aquatic plants.
