Baking Soda\/ Potassium Bicarbonate Fungus Control<\/strong><\/p>\n Mix 4 teaspoons (about 1 rounded tablespoon) of baking soda and 1 tablespoon of horticultural oil into one gallon of water. Spray lightly on foliage of plants afflicted with black spot, powdery mildew, brown patch and other fungal diseases. Avoid over-using or pouring on the soil. Potassium bicarbonate is a good substitute for baking soda. Citrus oil and molasses can be used instead of horticultural oil.<\/p>\n Compost Tea<\/strong><\/p>\n Manure compost tea is effective on many pests because of certain microorganisms that exist in it naturally. Here’s how to make compost tea at home. Use any container but a plastic bucket is easy for the homeowner. Fill the 5-15 gallon bucket half full of compost and finish filling with water. Let the mix sit for 10-14 days and then dilute and spray on the foliage of any and all plants including fruit trees, perennials, annuals, vegetables and roses, and other plants, especially those that are regularly attacked by insects or fungal pests. It’s very effective for example on black spot on roses and early blight on tomatoes. How to dilute the dark compost tea before using depends on the compost used. A rule of thumb is to dilute the leachate down to one part compost liquid to four to ten parts water. It should look like iced tea. Be sure to strain the solids out with old pantyhose, cheese cloth, or row cover material. Add two tablespoons of molasses to each gallon of spray for more power. Add citrus oil for even greater pest killing power. Cornmeal Juice<\/strong><\/p>\n Cornmeal Juice is a natural fungal control for use in any kind of sprayer. Make by soaking whole ground cornmeal in water at one cup per 5 gallons of water.\u00ac\u2020\u00ac\u2020 Strain the solids out and spray.\u00ac\u2020 The milky juice of the cornmeal will permeate the water and this mix should be sprayed without further diluting. Cornmeal Juice can be mixed with compost tea, Garrett Juice or any other natural foliar feeding spray.<\/p>\n
