Is it legal to use a pesticide for an intended use not listed on its label?

Using a pesticide for an intended use not specified on its label is illegal. Pesticide labels are legally binding documents that provide specific instructions and restrictions to ensure safe and effective use. The Environmental Protection Agency (EPA) regulates pesticide usage, and any application outside of what is labeled can lead to environmental harm, risk to non-target organisms, or exposure to humans and pets.

The label is considered a part of the law. Therefore, using a pesticide contrary to its instructions can result in severe penalties, including fines and loss of licensure. This regulatory framework is intended to protect public health and the environment.

In some cases, states may have additional regulations, but generally, the federal standards set by the EPA provide a baseline that must be adhered to nationwide. Thus, the notion that it might vary by state does not apply to the legality of using pesticides beyond their labeled uses.
