Fish Emulsion as a Fertilizer and Fungicide

Although most organic gardeners have used fish emulsion as an effective fertilizer for crops, recent research suggests that it can also be used as a fungicide to fight diseases as well. Researchers at McGill University in Canada applied fish emulsion to sandy-loam soils at 1% and 2% (by weight) rates. The soils were infected with a common verticillium fungus that attacks a broad range of garden plants. After one day the verticillium fungal spores in the soil were reduced 39% to 74%. After three days the reduction was 87% to 98% and after six days close to 99%. Fish emulsion?s mixture of organic acids had an immediate deleterious effect on the disease spores and continued to work for up to a week killing the verticillium fungus. They also found similar results when applying fish emulsion to soils and monitoring damping off (Pythium) fungal disease on cucumbers.
