Pesticides containing copper sulfate monohydrate and/or copper sulfate anhydrous have been cancelled by the United States Environmental Protection Agency (U.S. EPA). Copper sulfate has been used in the United States since the 1700s, and it was first registered for use in the United States in 1956.
Eating large amounts of copper sulfate can lead to nausea, vomiting, and damage to body tissues, blood cells, the liver, and kidneys. With extreme exposures, shock and death can occur. Copper sulfate affects animals in a similar way.
Copper sulfate easily dissolves in water and when combined with lime, which stabilizes the copper, it is safe to use on plants with little fear of tissue injury. New formulas that use copper as a fungicide use a form that is less soluble and fixed, causing even less chance of damage to your crops.
You can't swim in it. Those are two big ringing bells. with its use. While it can control algae and other unwanted plant growth, it can also negatively impact the health of fish and different aquatic life and the environment.
Copper sulphate is a powerful oxidizing agent and depending upon the dose ingested, it can lead to widespread cellular damage. The systemic effects of poisoning are seen primarily on red blood cells, gastrointestinal system, kidneys and cardiovascular system. The ingestion of poison can be lethal in severe cases.
Copper is possibly unsafe when taken in larger amounts. Kidney failure and death can occur with as little as 1 gram of copper sulfate.
Hemolysis. Copper sulfate can lead to hemolysis by accumulating in red blood cells.
Copper sulfate is a way to treat the water and kill the algae but can lead to high copper levels in the water, which can be harmful to cattle.
Used in the recommended dosage, copper sulfate will not interfere with septic tank operation. It should be remembered that neither mechanical removal nor copper sulfate treatment will prevent further root growth problems unless the trees or shrubs are removed.
If the treated water is to be used as potable (drinking) water, the concentration of copper sulfate must not exceed 4 ppm. This concentration is also expressed as 1 ppm Cu. It is recommended that swimming is not allowed for 24 hours. Sheep are extremely sensitive to copper; do not allow sheep to drink treated water.

a suspension of copper(II) sulfate (CuSO4) and calcium hydroxide (Ca(OH)2), is used to control fungus on grapes, melons, and other berries.
In a plastic container dissolve one teaspoon of copper sulfate dissolved in a gallon or so of water. This will treat a 300 square foot area with an average depth of 1 foot. For example, a 600 square foot area that is 2 feet deep on average will require 4 teaspoon of copper sulfate.
Pesticides containing copper sulfate monohydrate and/or copper sulfate anhydrous have been cancelled by the United States Environmental Protection Agency (U.S. EPA). Copper sulfate has been used in the United States since the 1700s, and it was first registered for use in the United States in 1956.
Generally, copper sulfate crystals should be used at 5 pounds per acre of pond. So, for instance, if you have a 1-acre pond, you should dissolve 5 pounds of crystals in three gallons of hot water first. For best results, treat your pond using the spraying method to kill the actively growing algae at the top and bottom.
DO NOT wash into sewer. Cupric Sulfate is harmful to aquatic life in very low concentrations.
Copper sulfate crystals can be found at your local hardware store or garden supply center. These crystals can be used to kill roots inside the sewer lines – by pouring one-half cup of crystals into your toilet, they can travel along the pipes until they come to the obstruction.
I found copper sulfate at Home Depot as Zep Root Killer, which is labeled as copper sulfate pentahydrate and is sold with septic tank and drain cleaning chemicals (not with other garden root killers or with other plumbing chemicals). This product contains solid granules of copper sulfate. It's very easy to work with.
Higher concentrations (175 ppm) of copper sulfate reduced plant productivity and health. Plants exposed to control and optimal concentrations (75 and 125 ppm) of copper sulpate exhibited the best health and growth compared to those subjected to higher concentrations.
A buildup of copper sulfate can lead to a sterile water bottom, which can decrease and kill beneficial bacteria. It is not natural and cannot be removed without the assistance of other chemicals or treatments. It is detrimental to plant and aquatic life.
An important consideration if your horses share their water trough with other animals: Copper is very toxic to sheep, although safe for horses, cattle, and dogs.
Among those, copper sulphate (CuSO4) is frequently used in organic farming practices as a fungicide (Katsoulas et al., 2020), especially when validated alternatives are not available or less cost-effective (Tamm et al., 2022).
The is corrosive to the eyes. The substance is irritating to the respiratory tract. The substance is severely irritating to the gastrointestinal tract. Exposure could cause haemolysis, kidneys and liver impairment.
Bordeaux mixture has been found to be harmful to fish, livestock and—due to potential buildup of copper in the soil—earthworms. The chemical was in use as a blight preventive in the potato country of northern Maine by 1921.
Why is anhydrous copper sulphate white and the pentahydrate blue? In hydrated CuSO4, the water molecules surrounding the Central Metal (Cu) act as ligands resulting in d-d transition and therefore emitting blue colour in the visible region due to which hydrated CuSO4 appears blue.
