Natural pesticides and fungicides 16 best recipes


What tests do not fall to the share of gardeners and gardeners - weather, weeds, insects, not to mention the problems of soil fertility. All this makes it difficult to get a crop, especially if you refuse to use chemicals.

We will tell you how to naturally control pests so that they do not turn your blooming garden into their own buffet.

There are two fundamentally different approaches - manual removal of insects (the method is time-tested, but incredibly complex and too labor-consuming) and the use of natural or home-made insecticides.

These tools will help get rid of pests and will not have a detrimental effect on the ecosystem of your garden.

Natural essential oils

Citrus essential oils perfectly protect against pests. Particularly effective: lemon, orange, bergamot, lemongrass. Conifers work worse.

Dissolve a few drops of oil and soap in 0.5 liters of water and irrigate the plants for prevention.

Himalayan pink salt

Himalayan salt is a natural inorganic pesticide. It contains 83 chemical elements, some of which destroy the shells of soft-bodied pests and prevent spores from growing fungi and mold. This salt works better than rock and sea salt (as they say, but I restrain such statements. Still, the main working substance in this case is banal sodium, not the homeopathic amount of molybdenum, gold, and something else in Himalayan salt). 1 tbsp per liter of water. It is possible to irrigate plants for prevention, but covering the soil can salinize the soil.

Hot peppers + garlic + onions

These natural pesticides in various combinations are most often found in recipes. Here is the basic recipe:

  • 2 teaspoons ground chili (hot pepper, cayenne)
  • Onion half
  • 3-4 cloves of garlic
  • 1 liter of water

Natural Laundry Soap

Probably, about the effectiveness of soap against, literally, everything, everyone knows. Apparently, the alkali in the composition of the soap is a good pesticide and fungicide, and the soap base helps the active substances stick to the plant.

Grate 10 grams of soap on a grater and dissolve in a liter of warm water. There are recipes with 2 tsp baking soda. But not only household soap appears in recipes for natural pesticides.

Liquid soap

Variations with liquid soap are increasingly common, and I think that due to the huge amount of organic and inorganic salts, liquid soap is effective in its own way in the fight against insects and molds.

Dissolve a teaspoon of liquid soap in a liter of warm water, treat the plant with a spray once every 2-3 days. Soda can also be added to this solution. There are recipes for a solution of liquid soap with rapeseed oil: 1 tbsp oil, 1 tsp soap and a liter of water. It was with such a mixture that Benjamin's ficus was saved, which was sick with something and dropped the leaves. after processing all overgrown.

Tobacco leaves

This is actually a good pesticide, but with one significant drawback - the tobacco mosaic virus, which I wrote about in this article, very often lives in tobacco. And it’s not at all suitable for processing nightshade (tomatoes, peppers, eggplant ...). Insist 0.5 cups of tobacco leaves in a liter of warm water during the day, strain and add a teaspoon of liquid soap (there are variations with milk - a glass of milk, 2 cups of water). Spray once every 2-3 days until the problem disappears.

Chrysanthemum flowers

Chrysanthemum has a powerful paralyzing pesticide in its composition, which copes with most garden pests. 0.5 cup dried or 1.5 cup fresh flowers, pour a liter of boiling water and simmer chrysanthemum over low heat for 20 minutes. I don’t like to cook herbs, I steam in a thermos, but in the original recipe it’s still cooking. Let the broth cool and strain. Irrigate a diseased plant.

Update as of July 11, 2017. I recently watched a lecture on chemistry, in which natural plant pesticides were mentioned. The substance in the chrysanthemum is a very powerful thing, in the production of concentrate and use in the so-called "bio-farming" it harms the health of people who work with it.


This drug has a dual effect. The secretions of its constituent bacteria (exotoxins) infect pests from the outside. But even more harmful for the enemies of plants are substances of the spore-crystalline complex, which kill from the inside.

The biological product is effective against moths, whites, sawflies, fireworms, the Colorado potato beetle, various caterpillars and many other agricultural pests. Moreover, it destroys harmful insects at different stages of development.

Their death occurs 3-5 days after processing the plants. Three times spraying allows you to completely eliminate the pest colonies.

After the last treatment, the fruits of cultivated plants can be eaten in 5-7 days.

Nemabact is the only drug of its kind, which includes predatory microscopic nematode worms. They eat the larvae of harmful insects, exhibiting this activity from spring to late autumn. Moreover, in winter, these "helpers" do not die, but fall into hibernation and, with the arrival of heat, again rush into battle with pests.

In addition, Nemabact contains a bacterium that lives in symbiosis and works “in pairs” with the nematode, releasing toxins that are toxic to harmful insects. Thanks to this, the drug is effective in combating Colorado beetles, wireworms, trills, weevils, bears, jungle beetles, bugs, gadflies, mushroom mosquitoes and other insects.

Attractive in the use of Nema-bacta is the fact that one treatment (the drug is applied to the soil) is enough to open the front against pests for 2-3 years. Predatory microorganisms multiply quite actively and literally attack the enemies.

But even if there are no insects and their larvae around, the predatory nematode does not die from exhaustion. It is able to exist without food for more than two years. The appearance of a nearby insect, which it immediately attacks, and uses its body as a breeding ground for reproduction, takes her out of a state of suspended animation.

In this case, the drug is completely harmless to humans and domestic animals, bees, fish, earthworms, beneficial insects.

It is necessary to bring the drug into the soil in the morning or evening (in the absence of direct sunlight) or during the day in cloudy or rainy weather. The ambient temperature should be in the range of 10-26 degrees, high humidity is desirable.

Rhubarb leaves

Rhubarb works thanks to organic acids. Pour a glass of finely chopped rhubarb with hot (not boiling water!) Water and let it brew for 24 hours. Strain, add a spoonful of soap. Irrigate until the disease or pest disappears. Suitable for prevention.

I myself use alcohol when in early spring the heating is weak and it becomes damp. Just at this time, the protective properties of the plant itself are weakening, since it is time to transplant and change the soil, and all sorts of scale insects and fungi on the surface of the soil are right there. I wipe the leaves of the plant with a cotton pad dipped in pharmacy alcohol, I do not breed. You can irrigate with alcohol, including window sills and window frames. This is a great tool literally from everything except viruses. Thyme sprinkled with alcohol when it brought a spider mite - it works.

Garlic + Mint + Pepper

This is a pesticide insecticide that works great for both treatment and prevention.

  • 5 peeled garlic cloves
  • 0.5 cups of dried mint leaves (or a glass of fresh, the stems are also good here)
  • 1 tsp hot pepper
  • 1 tsp dishwashing liquid or liquid soap
  • 1 liter of water.

Put everything in the processor, except for water and soap, and grind it into the paste. Mix the paste with water and bring to a boil, leave to cool for 12 hours. I would pour boiling water over the pasta, without cooking. Strain, add soap and irrigate the plants.

Chamomile works well against fungal infections of plants and soil. Pour 1 cup of dried chamomile flowers in a thermos and pour a liter of boiling water. Thermos is a good alternative to cooking in a water bath, and if you have the opportunity to steam the grass in a thermos, it is better not to boil the herbs on gas. Let it brew overnight, strain. This infusion can be irrigated and watered plants. If mold appears on the ground, we must first dry it and then add extra moisture.

About acetylsalicylic, you need to write a separate article, but for now this recipe: 2 tablets of aspirin (300 mg each) per liter of water - we irrigate and water. This is one of the best remedies against powdery mildew, gray rot, black legs. I myself have not tried and yet understood the mechanism of acetylsalicylic acid as a pesticide or fungicide, but I am already collecting the material. Reviews for aspirin are good.

Lemon juice

Cut off the skin with 5 lemons, pour 0.5 liters of boiling water and leave to infuse for a day. Squeeze the juice from the lemons and add a glass of water, irrigate the plants with aphids or other soft-bodied insects with fresh juice. Lemon juice is undesirable to get into the ground. Flush lemon peel with water around the infected plants, for prophylaxis repeat once a month.

Why peels: lemon juice acidifies the soil, and not all plants like it. The zest contains active essential oil, which aphids cannot tolerate. This applies, in principle, to most citrus essential oils.

A good natural remedy for fungi. Mix 1 tablespoon of soda with 1 tablespoon of vegetable oil, stir in a glass of well warm water. Next, pour the mixture into 1.5 liters of water. Spray every other day until the fungus leaves. There is one drawback - soda greases the soil, so you need to use the product without fanaticism, and pay attention to the recipe with milk.

General recommendations for using any means

  1. Before treating the plant, try the product on a separate leaf or branch to make sure there are no side effects. Sometimes you can not calculate the concentration, sometimes a particular plant may not be suitable for one or another ingredient.
  2. Apply the mixture on the inside of the leaves and on the stems, treat the soil if the product does not acidify or grease the soil.
  3. On processing days, remove the pots from direct sunlight.
  4. Do not forget that any sprayed substances, whether they are at least 100 times natural, have active ingredients that, when inhaled by a person, can cause serious discomfort (especially with hot peppers in the composition and essential oils) so use protection!

The authors of most of the recipes I have collected note that ladybugs and bees do not suffer from natural pesticides, since the concentration of active substances is much lower. This is very important, since involuntarily exterminating these insects, we can leave our fields without pollination and natural protection from soft-bodied pests ...

Update as of July 11, 2017. Modern crop protection products are tightly controlled for toxicity, biodegradability and effects on pollinating insects.

I want to share a lecture by chemist Sergei Belkov on organic farming.

1. Oil spray

Homemade insecticide made from vegetable oil mixed with liquid soap. It has a destructive effect on some harmful insects, such as aphids, ticks, thrips.

For cooking: mix 1 cup of vegetable oil with 1 tablespoon of liquid soap (cover and shake thoroughly).

How to use: 2 teaspoons of oil spray add to 900 ml of water, shake well and spray directly on the surface of plants that suffer from small pests.

Oil covers the bodies of insects, blocks the pores through which they breathe.

2. Soap spray

It looks like an oil spray, effective for combating ticks, aphids, whiteflies, bugs and other hungry small insects.

For cooking: mix 1.5 teaspoons of liquid soap with 900 ml of water.

How to use: Spray the mixture directly onto infected plant surfaces.

It is recommended to apply as needed, preferably in the evening or in the early morning.

3. Nim wood oil

The oil extracted from the seeds of the tree is a powerful natural insecticide that can affect both adults and insect larvae and eggs, which makes it an excellent resource for organic gardening.

It is effective against various common pests, and is also a natural fungicide, helps in the fight against powdery mildew and other fungal diseases of plants.

Oil is not toxic to domestic and wild animals, birds and fish.

It can be found in natural food stores or Indian goods.

For cooking: 2 teaspoons of neem oil and 1 teaspoon of liquid soap, mix thoroughly with 1 liter of water, and then spray on the affected plant.

How to use: Spray the plants. It can also be used prophylactically by spraying the leaves of plants before they are infected by insects.

4. Diatomaceous earth

This natural substance with a somewhat bulky name is an ancient sedimentary rock formed from diatoms.

Diatomaceous earth has many uses and its use as a natural insecticide is just one of them.

Diatomaceous earth can be bought at garden stores.

How to use: just sprinkle it around your plants or even sprinkle it on the foliage of plants - this will help control snails and slugs, as well as other crawling insects.

In order to have the effect of using diatomaceous earth, it must be reapplied after every rain.

5. Garlic Spray

Using the garlic and Chilean spray (see below), you can scare off insects, bring down or even destroy the infection of plants.

Garlic is well known for its pungent aroma, which is attractive to some and at the same time repels others. It is this strong aroma that is the basis of the use of garlic as a natural insecticide.

For cooking: take 2 whole garlics (not 2 cloves) and wipe them in a blender or food processor with 100 ml of water. Leave it overnight, then pour it into a liter jar of water, adding 1/2 cup of vegetable oil (optional), 1 teaspoon of liquid soap and enough water to fill the jar.

How to use: Mix 1 cup of the mixture with 1 liter of water and spray liberally onto infected plants.

6. Chili pepper spray

Like a spray with garlic, a spray with chili peppers is an excellent home-made natural remedy that can be used against various pests.

A chili spray can be prepared either from fresh hot pepper or from ground chili.

For the preparation of ground pepper: mix 1 tablespoon of ground chili with 1 liter of water and a few drops of liquid soap.

With this mixture, the leaves of affected plants can be treated.

To make fresh chili peppers: mix 1/2 cup of pepper with 1 cup of water with a blender, then add 1 liter of water and bring to a boil. Allow to brew until cool, then strain and add a few drops of liquid.

Hot chili peppers can be very irritating to people, so be sure to wear gloves when working with them and keep the spray made from them away from the eyes, nose, and mouth.

We hope that the above recipes for natural insecticides will serve as a good starting point for moving away from chemicals.

By carefully monitoring the effects, you can change the ratio of ingredients so that the tool is better suited for your battles with pests.

Just remember that killing all the insects in your garden is not the desired result.

Any healthy ecosystem requires an abundance of beneficial insects, germs and fungi, both in the soil and on the plants themselves. There are insects, such as ladybugs, praying mantises, which can also be an effective approach to pest control.
