Ornamental & Tree Diseases
At the end of each season I have leftover fungicides and other pesticides. Will it be okay to use the fungicides and other products the next season for control of pests in my landscape?
Many leftover fungicides may be used the second year (or additional seasons) provided they have been stored properly. What are "proper storage" conditions? Refer to an issue of Plant Pathology Infobytes Leftover Fungicides - Are They Safe For Use This Season? for more information on this topic.
