Fungicides are used on millions of acres of agricultural crops, to control disease and increase yield harvest. However, current products have high chronic toxicity and many are suspected human carcinogens and/or teratogens and may not be re-registered under the Food Quality Protection Act. Summerdale, Inc. has showed that selected fatty acids and other compounds have efficacy as fungicidal active ingredients (Als), against a wide range of pathogens. Earlier work on herbicidal formulations has also shown synergistic combinations between certain fatty acids and an amendment. The economics for effective application rates of Als at this stage of development appears attractive. If Phase I efficacy is demonstrated, a strategic partner may wish to participate. This proposed work would develop predominantly natural compounds and will meet grower criteria for shifting to a new product. A range of fatty acid species and other compounds will be tested individually and with other compounds, to examine possible synergistic relationships. Extensive laboratory and greenhouse trials on potatoes, soybeans and peanuts will be conducted prior to extensive field trials (Phase II), to determine effective application rates, emulsification systems and adjuvants.
