Fungicides
Fungicides can be applied when necessary to address occurrences of early blight and late blight, downy and powdery mildew, leaf spot, black rot, Fusarium, Pythium, Rhizoctonia, and other crop-damaging fungal pathogens. Most of our fungicides are approved for use in certified-organic production by the Organic Materials Review Institute (OMRI), and some by the Washington State Department of Agriculture (WSDA). Look for our OG symbol, as well as the OMRI and WSDA symbols in our product descriptions. For specific recommendations, refer to our Fungicide Comparison Chart (at right).
