Something most homesteaders will have to face sometime and maybe even have to be in constant battle with is blight. It wreaks havoc on our tomato and potato plants and causes us huge losses in harvest. In this members only live chat I will discuss a few preventive methods as well as some treatments.
Here Is What We Discuss In The Live Chat:
What is Blight?
Early Blight is caused by a fungal pathogen named alternaria solani. It can affect both tomatoes and potatoes. Early blight can be identified on foliage by the small sunken lesions that are brown to black in color. These leaf spots resemble concentric rings much like the rings you see in trees when cut down.
- Proper Pruning – https://www.wikihow.com/Prune-Tomatoes
- Whole Ground Cornmeal applied around plant will feed the beneficial microorganisms that can destroy the fungus.
- Mulch around plants to prevent soil from splashing on plant when it rains.
- Water the soil around the plant low, not the plant itself.
- Separate plants throughout the garden.
- Crop Rotation.
Remove the infected leaves to keep the fungus from spreading. Clean hands and pruners between cut to not spread the fungus with a bleach or hydrogen peroxide/water mix.
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. Strain the solids out and spray. 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 or any other natural foliage feeding spray.
Baking Soda Fungus Control – Mix 4 teaspoons of baking soda and 1 tablespoon of horticultural oil (citrus oil or molasses can be used instead) 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.
Vinegar Fungicide – Mix 3 tablespoons of natural apple cider vinegar in one gallon of water. Spray during the cool part of the day for fungal diseases. Adding molasses at 1 tablespoon per gallon will help.
Destroy any infected prunings or plants by burning or removing from property. Do not add to compost!
