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.
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.
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.
As an added bonus, hydrogen peroxide can help discourage unwanted bacteria/fungi that may be lurking in the garden. To give plants an added boost of oxygen or for pest control using the 3% solution, add 1 teaspoon (5 ml.) per cup (240 ml.) of water in a spray bottle and mist the plant.
Prevent Fungal Disease
Give this natural remedy a try. MAKE IT: Mix 1 teaspoon of baking soda and 2-3 drops of liquid soap in 1 liter of water. Spray the solution on the infected plants. Baking soda helps the plants become less acidic and prevents fungal growth.
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.
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.
If you do encounter fungus on your plants, just remember it can be treated and your plants will more than likely recover beautifully. Learn how to recognize powdery mildew and black spot, and how you can prevent and treat them in your own garden.
It is perfectly safe for plants when properly diluted and used in moderation. Adding hydrogen peroxide to water promotes better growth in plants and boosts roots ability to absorb nutrients from the soil. Diluted 3% peroxide adds needed aeration to the soil of plants and helps control fungus in the soil.
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.
Vinegar spray
You can also add half a teaspoon of dishwashing soap to help the solution adhere. Shake thoroughly and apply to the affected areas. The acetic acid in the vinegar will treat a wide range of garden pests but it requires contact. If you have whitefly eggs be sure to spray under the leaves.
Use on stone and pip fruit trees, citrus, vines, plants, vegetables and roses. Spray in June or July and again from when buds are only just beginning to show as small bumps, then fortnightly through until leaf fall. Mix 1 tablespoon DYC Apple Cider Vinegar with 1 litre of warm water in spray bottle.
Boosting growth
Just like using coffee grounds as a fertilizer, the best part of using cinnamon to boost plant health is that it's completely safe and non-toxic. 'Unlike chemical pesticides, fungicides, and fertilizers, cinnamon won't harm beneficial insects or contaminate your soil and water supply,' Richa notes.
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.
To eliminate Fungal Infections
When the plant needs watering, flush water with a 1/4 cup of H2O2 3% with 4 cups of water.
Will baking soda safe kill plants? In the same way that baking soda will kill and prevent weeds when used full strength, it will also kill plants. So be careful not to get the baking soda on desirable plants nearby or your lawn.
