Baking soda (sodium bicarbonate) is an effective and inexpensive antifungal agent that is readily available at a supermarket. It is an organic and eco-friendly remedy for black spots and fungal diseases such as powdery mildew. Fungus can quickly damage plants and cause plants to wilt and die.
Making Fungicide with Baking Soda
1 Ltr. Water
1TSP Baking Soda
1TSP Natural Castile Soap
2 TSPs of Vegetable Oil
All of the above can be sourced from a supermarket or purchased online. Mix them together and spray on your plant’s leaves twice a month as a preventative measure; or spray on the leaves every three days to treat an existing fungal problem.
You can also spray near the base of plants to kill and prevent slugs, cutworms and fungal outbreaks such as powdery mildew. In addition, this mix protects against aphids, whiteflies, thrips, caterpillars, spider mites, roaches and ants.
When the mix is consumed by insects it releases carbon dioxide into their system which kills them. The vegetable oil suffocates them and also repels fungal spores.
Before using the mix, please carry out a patch test to avoid any kind of sensitivity issues.
Apart from being an effective fungicide and insecticide, the Baking Sodar Spray has other advantages like:
