Read the label of each product under consideration to be sure that it can be used in the place and the manner you intend. For example, if the label indicates that the material is toxic to fish, do not use it on plants along the border of a pond. If the label requires that you wait two weeks from the time that you spray until you harvest, it should not be used on vegetables or fruits that are almost ripe. Consider all uses of the site to which the pesticide will be applied and protect children, pets, and wildlife by careful pesticide selection and use. You should purchase only the amount of pesticide you anticipate using in one season.
Most pesticides have a limited shelf life.
If pesticides are stored, they must be protected from extreme heat and cold, and must be kept in a secure, locked place. Read the storage section of the product label prior to purchase, and do not buy a product that you can't store as directed. Also, remember that pesticides must be kept in their original container with the label intact. Choose the least toxic product. Compare pesticides based on how hazardous they are.
