How to replace fungicide at home: ingredients and how to use

The conditions necessary for breeding indoor plants often favor the emergence of a fungal infection, the appearance of colonies of insect pests. Natives of tropical forests require frequent watering, partial shade, lack of drafts. In an apartment, it is difficult to fight infection using synthetic means of protection, because of the danger to human he alth. What can replace the fungicide at home?

What can replace the fungicide at home?

Manufacturers of plant protection products offer a wide range of chemical compounds.It is often inconvenient to use them indoors due to toxicity to humans and animals and the need for prolonged ventilation. Fungicidal properties have natural organic and inorganic substances. Knowing how to properly prepare a remedy at home, you can successfully deal not only with moldy fungi, but also with insect pests.

As improvised means for fungicide can be used:

s alt;
soda;
milk;
ethyl alcohol;
citrus;
vegetable crops;
tobacco;
ornamental and wild plants.

In most recipes for home fungicides, liquid soap is a must-have ingredient to ensure that the composition sticks to the ground parts of the plant. Without this property, the effective effect of the fungicide on the surface of leaves and stems is impossible.

Milk and s alt

From powdery mildew, a fungicide based on a water-milk-s alt solution is used. Milk and water are mixed in equal proportions (200 milliliters each) and 20 grams of s alt are added. Leaves and stems are treated with a sprayer 2-3 times a day, before isolating the soil in a pot. Sodium chloride inhibits the development of any microflora. Milk has enough stickiness to keep a certain concentration of s alt on the plant.

Rapeseed oil and soap

Rapeseed oil has a bitter taste and good adhesion. To repel pests, just add 1 tablespoon of rapeseed oil and a teaspoon of liquid soap to 1 liter of warm water to get a homemade fungicide.

Natural essential oils

Lemon, orange, bergamot essential oils have a depressing effect on the development of fungi, viruses, leaf-sucking insects.In high concentrations, the oils have a burning effect. For spraying infected plants or as a preventive measure, 4-5 drops of oil and liquid soap are dissolved in 500 milliliters of water. Processing is carried out within 7-10 days, in the morning and in the evening. Essential oils of coniferous plants are not used as fungicides.

Himalayan pink s alt

Himalayan s alt comes from s alt mines in Pakistan. Unlike rock s alt, sea s alt contains a large list of trace elements, the total amount of which in the mass fraction does not exceed 2-5%. The pink color of s alt is given by polyhalites: sulfates of magnesium, potassium, calcium.

Fungicidal and pesticidal effects of s alt solution give sodium chloride and potassium s alt. Pest larvae do not tolerate the s alty taste of leaf blades. For spraying, a little liquid soap is added to a 5% solution. The soil is protected from s alting.

Hot pepper+garlic+onion

Chili and cayenne peppers have a spicy taste. In combination with onions and garlic, a fungicide is obtained that repels parasitic insects. To obtain a caustic solution, the onion and garlic (2 medium cloves) are rubbed on a fine grater, 2 teaspoons of ground pepper are added. All ingredients are mixed and poured with 1 liter of water at a temperature not exceeding 50 degrees to preserve phytoncides. Time of infusion - 24 hours. The fungicide solution is filtered and stored under a tight lid. Add a teaspoon of liquid soap before spraying.

Garlic+mint+pepper

Instead of onions, you can add mint to the natural fungicide. To prepare a caustic base, 20 milliliters of water is poured into a blender. Add peeled cloves from half a head of garlic, 1 teaspoon of ground pepper and mint (dried or fresh in a ratio of 0.5 cup or about a cup).

Turn all the ingredients into a homogeneous paste and pour 1 liter of boiling water. Insist under a tight lid during the day. Filter. Add a teaspoon of soap before use. Affected plants are irrigated once a day until the symptoms of infection disappear.

Chamomile

Chamomile infusion has antiseptic properties, it is used against moldy fungi on a houseplant and soil in a pot. Fungicide is prepared in a water bath or steamed in a thermos. For 1 liter of hot water / boiling water, you need 1 cup of dried chamomile. In a water bath, the infusion is prepared for 15 minutes from the moment the water boils in the container. Exposure time in a thermos - 12 hours.

The finished infusion is filtered and used for washing leaves and stems or watering. If mold appears on the soil layer, allow it to dry out before moistening again.

Aspirin

Acetylsalicylic acid can be used as a fungicide when powdery mildew, gray rot, black leg appear on indoor flowers.For 1 liter of warm water, you will need 600 milligrams of a synthetic agent. After complete dissolution of the tablets, the plants are treated using a soft sponge. The procedure is repeated until the symptoms of infection disappear.

Lemon juice

To combat aphids, the use of lemons will be effective. An infusion is prepared from the lemon peel to water the soil. The peel from 5 lemons is placed in a thermos and poured with 500 milliliters of boiling water. Leave for a day. The resulting infusion is used for irrigation, as the aroma of essential oils contained in the peel repels aphids.

Leaves and stems are irrigated with diluted lemon juice from 5 fruits and a glass of water. Irrigation of the ground part is carried out by isolating the soil so as not to cause acidification of the soil. The duration of sanitary treatment with a fungicide depends on the degree of aphids infestation: from 3 to 7 days.

Soda+oil

Sodium bicarbonate, when dissolved in water, forms an alkali, the aggressive properties of which help fight fungal infection in plants.For better adhesion, mix 1 tablespoon of soda and vegetable oil. Pour this mixture into a glass of hot water. Mix well and dilute with 1 liter of warm water. Spray the resulting composition every other day.

Natural laundry soap

Laundry soap contains up to 0.2% alkali, due to which it has antibacterial properties. The soap base enhances the action of the natural pesticide against aphids. The composition of the solution: 10 grams of grated soap and 1 liter of hot water. Soap must be completely dissolved in water to form a homogeneous soapy solution.

Liquid soap

The main components of liquid soap that provide washing properties are potassium stearate and potassium hydroxide (KOH or caustic potash). The use of a 1.5% solution gives a good result when used against insects and mold. To enhance the inhibitory effect, baking soda or rapeseed oil can be added to the solution.

Tobacco leaves

Dried tobacco leaves, crushed to a powder, are an insecticide and a fungicide. Nicotine is toxic to houseplant pests and pathogens:

thrips;
phish;
spider mites;
powdery mildew;
grey rot.

Tobacco powder is used to pollinate the soil and water it abundantly. Frequency of processing - 1 time in 3 months.

Norms for applying tobacco dust to flower pots (in grams):

in small - 50;
medium - 100;
large - 150.

It is not recommended to use other fungicides during tobacco treatment.

Chrysanthemum flowers

Chrysanthemum petals contain coumarin, a substance that has a neurotoxic effect on living organisms, including indoor pests. To obtain the current composition, the flowers are poured with boiling water and insisted in a thermos. The ratio of water and flowers: for 1 liter - half a glass of dried or 1.5 cups of fresh flowers.

Rhubarb leaves

Fresh rhubarb leaves are finely chopped and hot water is added at the rate of 1 cup per 1 liter. A container with a tightly closed lid is placed in a warm, dark place for 24 hours. Then filter and add a tablespoon of liquid soap. Spray plants until pests disappear and become infected.

Alcohol

Ethyl 70% alcohol does not burn the leaves of indoor plants. Wiping the leaf plates with a cotton swab dipped in alcohol helps get rid of the spider mite. As a preventive measure, you can wipe the window sill and window frame.

General recommendations for the use of natural fungicides

Natural fungicides and insecticides should not be applied to the whole plant at once. The concentration indicated in recipes may not be suitable and cause burns on leaves and stems. Preliminarily check the result of exposure after processing on 1-2 leaves for several days. When processing, it is necessary to distribute a toxic or neutralizing substance, both on the outer and inner parts of the leaves. To avoid s alting the soil layer in the pot, cover it with polyethylene during processing.

When carrying out protective procedures, plants should be protected from direct sunlight. When spraying with compounds with a pungent odor, essential oils, it is useful to use protective equipment for the respiratory organs and skin of the hands.
