SEMEL, MAURIE. 1985. Proper pesticide use doesn’t end in the field. Am. Nurseryman 161(12): 39, 42-45, 48-50, 52, 54-55.

Properly used, pesticides permit the production of clean, healthy, vigorous, and aesthetically pleasing plants. Proper use, however, does not end with spraying in the field. Safe storage of these chemicals is as essential as safe application. Because of the great variability in pesticides, including their chemical compositions and formulations, specific storage instructions are not required on the label by federal regulation. However, all registered pesticides must include up-to-date storage and disposal statements. These statements must be set apart and clearly distinguishable from other directions for use. As a general rule, pesticides should not be stored longer than two years, although many will last indefinitely under proper storage conditions. Generally, insecticides, fungicides, nematicides, and rodenticides may be stored in the same room or cabinet. Herbicides, on the other hand, are apt to contaminate other chemicals or supplies by the emission of certain volatile components or by physical contact. Conditions most likely to affect pesticide shelf life are excessive heat or cold and high humidity. Local building and zoning regulations should be consulted before embarking on any new construction or modifying an existing structure.
