Cornmeal Juice is a natural fungal control for use in any kind of sprayer. Make by soaking horticultural or whole ground cornmeal in water at one cup per gallon of water. Put the cornmeal a nylon stocking bag to hold in the larger particles. The milky juice of the cornmeal will permeate the water and this mix should be sprayed without further dilution. Cornmeal Juice can be mixed with compost tea, Garrett Juice or any other natural foliar feeding spray. It can also be used as a soil drench for the control of soil borne diseases.
We have several reports that mange has been controlled with cornmeal juice dips. In this case the solids don't even have to be strained away. Use about one cup of whole ground cornmeal or horticultural cornmeal per 5 gallons of water.
