Corn Meal, Nature's Guide
Corn meal offers powerful natural fungus control. It may also be effective on other soil-borne diseases. Apply to soil at 10-20 pounds per 1,000 square feet. Use at 20 pounds per 1,000 square feet or 200-800 pounds per acre to add cellulose and stimulate the beneficial microorganism that controls several disease pathogens such as Rhizoctonia, Pythium, Fusarium, Phytophthora, and others. Can also be used in pools and water features to control algae at 2 cups of cornmeal per 100 square feet or 150 pounds per acre. It is also useful on pond algae. Apply to ponds and lakes at 150-200 pounds per acre to control algae.
