Sample Pesticide Labels

The following links to pesticide labels are intended solely to assist students in Arboriculture 101 in learning about pesticide labels, including what information exists on these labels and how to read them. These labels are not intended to be substitutes for the labels that belong with any specific pesticides. Pesticide product registrations and product labels are subject to being revised under FIFRA. As a result, the labels listed below may not be and should not be assumed to be the same as the label for any product you are likely to use.
The most important thing to remember is that the label instructions that you are following must be from the label that specifically belongs to the material you are using. The label is the law. Make sure you are using the right label!
