Project Information


Foliar disease is a major problem in heirloom tomato production, so we set out to determine if aerated compost teas could be part of the solution. We planted blocks of Cherokee Purple tomatoes and applied two types of tea and water to sections within each block. The teas were applied each week and samples were taken of the tea, treated leaves, and foliar disease. We found that the compost tea did not have an effect on crop yield or timing of disease onset. This method of disease prevention may work if growing conditions are better, but doesn’t work in the humid South for susceptible varieties.
