The following list of chemicals is designed for informational purposes and is not an endorsement of any product. In some cases, particularly those where the active ingredient is no longer protected by the patent, and a number of similar products are marketed by different registrants, every registered product that may be used on mushrooms may not be listed. Omission of any such product from the list is not intended to suggest that it cannot or should not be used on mushrooms; these products can be used if the label includes instructions for use on mushrooms.

The information on this website is gathered from pesticide registrants, EPA publications and trade publications. The American Mushroom Institute believes the information to be accurate, but cannot and does not warrant or guarantee the accuracy of all information.

We strongly suggest, as an added precaution, that you check with local, county and state authorities to determine whether they have imposed restrictions on pesticide use that differ from those imposed by the EPA. In addition, users of this website are advised to contact the manufacturers for the most current product information, including information on supplemental labels.

The American Mushroom Institute hereby disclaims any and all responsibility or liability, which may be asserted or claimed arising from, or claimed to have arisen from, reliance upon the information contained herein by any entity or person.
