A good place to start is a mix of mild liquid soap and water, sprayed onto houseplants. One teaspoon of soap per litre of water will do the job. It sounds simple, but this formula will treat a lot of common houseplant pests. Add just a teaspoon of bicarbonate of soda and it becomes a great fungicide as well.
Make a typical baking soda spray by dissolving one teaspoon of baking soda into one quart of water. You can add a few drops of insecticidal soap or liquid soap to help the solution spread and stick to the leaves. Only use liquid soap, like Ivory, and not laundry detergent.
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.
Homemade Fungicide
baking soda, 4 tsp. liquid dish soap and 1 gallon water. Spray the mixture on plants weekly to prevent and control fungal diseases in the vegetable garden. This treatment is also effective on roses and other ornamental plants.
Triclosan is a pesticide that is found in Dawn dish soap.
It is there in controlled amounts, but it exists to kill the bacteria and germs on your dishes and surfaces. It is an organic antibacterial and anti-fungi agent that is toxic to the environment.
There is a general misconception that any soap can be used as an insecticide. Dishwashing liquids are primarily designed to dissolve grease from dishes and clean clothes, not to kill insects. Dish detergents may dissolve the protective waxes on the plant leaves.
Vinegar is a proven method for destroying mold and eliminating pesky white spots from your plants. Mix two tablespoons of apple cider vinegar with a quart of water, and spray onto your infected leaves and stems.
Apple cider vinegar as fungicide on plants- To make a fungicide out of this, take one tablespoon of vinegar and mix it with a gallon of water. Shake this well and add to a spray bottle. Vinegar mixture can treat most fungal infections on any plant, without causing any harm.
Sodium bicarbonate as a fungicide works by disrupting the ion balance in the fungal cells, which causes them to collapse. The biggest danger in using sodium bicarbonate on plants is the potential for foliar burn.
Hydrogen peroxide, well known as an ingredient in disinfectant products, is now also approved for controlling microbial pests on crops growing indoors and outdoors, and on certain crops after harvest. This active ingredient prevents and controls bacteria and fungi that cause serious plant diseases.
Bicarbonates (Baking Soda)
Bicarbonates, like baking soda, have also been used as a natural option for fungicides for a long time. Ammonium bicarbonate and potassium bicarbonate are recommended over baking soda. This is because they are effective without the additional use of oils.
There is no scientific evidence indicating that Epsom salt can control or manage fungal or bacterial pathogens in plants. Epsom salt can help if a recent soil test indicates that there is not enough magnesium for the type of plants being grown.
Change the conditions around the plant to be less humid and warm, and water less often (but be careful not to harm your plant). Pull the mushrooms out by the base of their stems and throw them away. Be careful not to shake more spores out of their caps if they've matured to that point.
Use ACV for fertilising your plants
Simply mix water with your apple cider vinegar and pour it into a sprayer or watering can. Spray this solution at the base of the plant, avoiding watering the leaves as this can often lead to wilting.
The results of the study show that apple cider vinegar is the most economical product to treat Candidiasis and other fungal infections.
Vinegar is non-selective, meaning it will damage any plants and turf grass it touches, not just the weeds you are trying to kill. When you spray the vinegar onto weeds, make sure it isn't hitting other plants. If that isn't possible, paint the vinegar onto the weeds with a brush.
As vinegar temporarily changes soil pH, it may be harmful to garden plants and roots so avoid applying too close to those areas (though such an application used just once or twice should be okay).
Vinegar can als be used as a fungicide on your plants. Mix up diluted mixture of 50ml to every 1L of water and spray on your plants.
It's not recommended to use dish detergent (like Dawn), laundry detergent, or hand soap (even the “natural” versions), since these soaps contain abrasive ingredients that could harm your plants. For DIY insecticide, organic pure castile liquid soap is the best solution since it's all natural and highly effective.
