Problems Caused by Fungi

As a study by WSU County Extension states, fungi are spore-forming, non-chlorophyte, eukaryotic (cells having true nuclei) organisms, and fungal infections cause general necrosis of host tissue, which often results in stunting, distortions, and abnormal changes in plant tissue and organs.

The most common sight of a fungal infection in plants is leaf spots. The typical fungal leaf spot will have a “bulls-eye-like” appearance, consisting of roughly concentric rings that may display zones of different colors.

Root-based fungi can kill the roots or cease the water-managing cells that result in plant wilting and death.

A study claims that sodium bicarbonate can inhibit the growth of 80% of all fungal isolates.

A report by the Cornell University, Ithaca, states that powdery mildew, caused by Sphaerotheca pannosa var. rosae, and black spot, caused by Diplocarpon rosae, can be significantly controlled by weekly sprays made with a solution of sodium bicarbonate.

Another study states that the application of baking soda reduces the development of powdery mildew fungus on leaves. It also helps to reduce the severity of fruit infections in plants.

Use it on plants like tomatoes, potatoes, cabbage, eggplants, and chayote.

The best way to do it is by making a foliar spray. You’ll need:

  • One gallon of water
  • 2 tablespoons baking soda
  • 2-4 wee bit drops of mild liquid dish soap
  • Clean spray bottle

Dissolve one tablespoon of baking soda in one gallon of water. Add liquid soap and stir the mixture thoroughly. Pour the solution into a clean empty spray bottle, shake well, and spray on the affected area. Repeat the application after 7-10 days if you notice the issues again.

If you find poor-quality flowers or leaf damage after using this spray, then reduce or remove the dish soap from this solution.

Note: Use the solution quickly and do not store it.
